Executive summary

Introduction

This report has been prepared for the Radiocommunications Agency (RA) by The Smith Group and National Economic Research Associates (NERA). It details the results of a study to examine the issues surrounding the application of economic value-based pricing to a number of sectors and licence classes under the provisions of the Wireless Telegraphy Act 1998. The sectors and licence classes considered are:

* Amateur and Citizens’ Band (CB);
* Aeronautical;
* Maritime;
* Fixed Satellite Services;
* Fixed point-to-multipoint services;
* Fixed Wireless Access (FWA);
* Test and Development licences (T&D);
* Programme Making and Special Events (PMSE).

The report presents the results of the study regarding the feasibility of introducing economic value-based pricing in each of the areas, and where appropriate calculates marginal values on which economic value-based prices should be based.

Economic value-based pricing

The objective of the Wireless Telegraphy Act 1998 is to base charges for wireless telegraphy licences on spectrum management considerations. That is to say, fees to install or use radio equipment should reflect more closely the value of spectrum instead of being tied to the fully allocated costs of spectrum management, as was previously the case. In previous reports, the new fees have been described as administrative prices. This is perhaps a little confusing, since in practice cost recovery based prices are also administratively set. To distinguish the two approaches more clearly, this report uses the term economic value-based pricing to describe fees set on spectrum management considerations.

Economic value-based prices are set at a level so as to influence the choices made by spectrum users, such that their use of, and requests for spectrum reflects the value they place on it. Under such a regime, users (and potential users) have incentives to release unused or under-used spectrum, to consider alternative services or less congested frequency bands, and to implement more spectrally-efficient technologies.

The primary objective of economic value-based pricing is to improve the efficiency with which a scarce resource (the radio spectrum) is managed, not to raise money. The general principle we adopt is that such a move is only likely to result in benefits if it induces users to change their spectrum use. Although such changes are likely to be slow to occur, because of the significant investment in existing technologies and services, this is not an argument against the application of economic value-based pricing. The application of the existing administrative rules to clear spectrum or to introduce new more efficient technologies also takes many years to implement for exactly the same reasons.

Suitability of candidate sectors for economic value-based pricing

Under the Wireless Telegraphy Act 1998, spectrum licence fees are to be based on spectrum management considerations for all sectors. The extent to which it is appropriate to apply economic value-based pricing may, however, vary due to a range of constraints which limit users’ ability to change their spectrum use in response to the new charges. The principal constraint is found to be where assignments are co-ordinated for international use, such that alternative uses of spectrum are limited or where changes to equipment used needs to be agreed internationally.

Table 1 summarises the suitability of the candidate sectors considered in this report for economic value-based pricing.

Recommended pricing policy

The prices recommended in this report have been calculated with reference to mobile and fixed link Spectrum Tariff Units (STUs). Following consultation on the first round of spectrum pricing, the RA has adopted the STU as a reference measure against which spectrum charges for different services are established. The use of the STU allows easier comparison of spectrum prices across different services and provides for greater transparency in licensing procedure and process.

Two widely accepted STU values have been established for mobile services and for fixed links, and have been applied to fees for services covered under the first two rounds of spectrum pricing. Since these services include the major and highest value spectrum uses, it is likely that they will represent the most likely alternative use and users for the services considered in this report. We therefore consider it valid to use these STUs as the basis for calculating target prices for these services.

The mobile and fixed link STUs are based on the estimated value of 1 MHz of spectrum over 1km2 across the UK. They were originally set at 50% of the calculated marginal value of the spectrum concerned. There are strong grounds for this cautious approach. In particular, while the marginal values on which they are based give a reasonable estimate of the prices that should be applied to ration spectrum in a static world, in reality the world is far from static and may give rise to reasons for both higher or lower values over time. As demand grows, marginal values might be expected to increase, although technological developments could help to reduce the costs of alternatives. Also, as users respond to prices, more spectrum should become available, putting downwards pressure on prices. The RA will therefore need to monitor subsequent market developments and modify prices accordingly.

Terrestrial Flight Telephone System (TFTS)

A price of £15,975 per 2x30 kHz TFTS channel has been calculated, based on the STU for fixed links, which are deemed to be the next best use (the service uses a band previously occupied by fixed links). This is considerably more than the current licence fee of £1,350. Following the precedent set in previous pricing exercises, we suggest that the increase be phased in over three years, at which point the situation will need to be reviewed again. This implies spectrum fees of £5,325 in year 1, £10,650 in year 2, and £15,975 in year 3.

CSR (UK)

CSR (UK) is currently priced at a flat fee of £180 pounds per channel per site. The main alternative use for the CSR (UK) band is PBR. We therefore recommend that spectrum fees for CSR (UK) should be based on PBR fees, which are already set subject to economic value-based pricing.

Based on 1999 PBR fees, this implies the following pricing regime for CSR (UK):

Minimum configuration CSR (UK); for each 12.5 kHz channel per site:

* £200 in a heavily congested area;
* £100 in a congested area; and
* £75 in a non-congested area.

Maximum configuration CSR (UK); for each 2x12.5kHz channel per site:

Table 2: Suggested fees for CSR(UK) based on wide area PBR licence fees

This approach could be simplified by making the licence fee independent of the number of users. If values were determined based on the average number of users, this could result in the following values:

* £400 in a heavily congested area;
* £200 in a congested area; and
* £150 in a non-congested area.

In order to provide an incentive for users to keep the transmitter power to the minimum required, a sliding scale of charges could be adopted between the maximum and minimum configurations.

Satellite Earth stations

We have calculated economic value-based prices for satellite Earth station uplinks by reference to the STU for fixed links, with which much of the spectrum is shared. Current licence fees and calculated prices are given in the table below.

Licence Current licence fee Reference price
Earth station(Class I)
bandwidth<100 kHz
£1,000 operating to one satellite.

£1,000 operating to each additional satellite.

£552 (for 100 kHz)

£55,286 (for 10 MHz)
£276,430 (for 50 MHz)
£1,105,720 (for 200 MHz)
Transportable Earth Station £8,500 Dependent on bandwidth requirements

Table 3: Reference economic value-based prices for Satellite Earth Stations

There are grounds for price increases for classes II and III and price reductions for class I earth stations. In addition, there is a case for introducing different prices for congested and non-congested areas in a manner similar to that adopted for fixed links (since fixed links are the main alternative use). We suggest that the RA consult with industry about how best to introduce differential fees for different area types.

Scanning telemetry

We have calculated an economic value-based price for scanning telemetry by reference to the STU for mobile spectrum, since there is already a high degree of sharing with PBR and public networks. The calculated price is £433 per base station per 2x12.5 kHz channel, compared with £40 per station (base station and outstations) at present.

Since the main alternative use of the spectrum is PBR, an obvious approach is to align prices with wide area PBR, with congestion defined in the same manner. This implies the following structure of fees:

Category

Table 4: Suggested prices for scanning telemetry licences

However a possible problem with this approach is that it may reduce the fees paid for what is already a congested part of the spectrum, with a risk that the congestion is exacerbated. The current fee of £40 per station is not directly comparable with the above, but based on a mobile STU of £1.65/MHz/km2, the 2 MHz of national spectrum allocated to scanning telemetry is worth £800,000. The 11,000 scanning telemetry stations currently in operation therefore generate fees of about £440,000 which indicates that the fees are already close (~55%) to the reference value of the spectrum.

Nevertheless, there may be some merit in adopting a pricing structure more closely matched to PBR, in particular a structure based more closely on bandwidth and area sterilised. An alternative simpler approach to the above might also be considered, in which a flat fee of £433 per base station is charged, irrespective of the number of outstations.

It may be noted that, as the operators already pay a significant fraction of the reference value of the spectrum and still suffer congestion, there might be a case for allocating more spectrum to them to reduce the amount of congestion.

As the operators form a well-coordinated community who co-operate extensively already, any change in the pricing structure should be made in consultation with the operators. Since the band is going to be re-planned in 2004 this might provide an opportunity to implement any changes to the current regime, giving the RA enough time to consult with the industry and to establish a pricing structure based more closely on the area sterilised and bandwidth used.

Fixed Wireless Access

We have calculated prices for FWA by reference to the fixed link STU. Current licence fees and calculated prices are shown in the table below.

2 GHz

£690 (assuming a 2MHz channel bandwidth)

£10,365 (assuming a 30 MHz channel bandwidth)

Table 5: Current and reference prices for FWA licences

FWA licences are generally issued on a national basis although in some cases, regional assignments are made. It is therefore more appropriate to relate the reference price to the area over which the licence applies, since this is the amount of spectrum for which access for other users is denied. In order to calculate the equivalent value of a national FWA assignment a re-use factor of 40, based on the value agreed for fixed links, is applied to the reference fee per base station.

Table 6: Calculation of reference economic value-based prices for national FWA assignments

Note that the re-use factor of 40 does not necessarily limit an operator to 40 base stations. In practice, a higher frequency re-use may be achieved.

In order to derive a price for regional licences the area covered needs to be considered as a proportion of the national value. It would also be appropriate to apply a weighting factor to take into account the population within the area covered by the licence.

A move towards economic value-based prices would imply a significant increase over current fee levels. If economic value-based pricing is to be introduced, then as before we suggest that increases are phased in over a three year period.

Prices for the 2 GHz band should be reviewed following the outcome of the UMTS auction, which will establish a market price for UMTS spectrum. The RA may also wish to consider the use of modifiers to adjust fees where the spectrum is shared with other users.

Programme Making and Special Events

There appears to be scope to modify the fee structure for PMSE to encourage more efficient spectrum use. Prices have been calculated by reference to fixed and mobile STUs, but definition of economic value-based prices is complicated by:

* the large range of current licence classes;
* the infrequent and highly variable use of spectrum by users; and
* the heavily shared nature of the spectrum.

This introduces a number of administrative complications to implementing a revised pricing regime. We suggest the RA consults further on this issue following publication of its study on the demand for PMSE spectrum. Consideration should be given to reducing the number of licence classes issued, and the impact of revised fees on different user types.

1. Introduction

1.1 General

This report has been prepared for the Radiocommunications Agency (RA) by The Smith Group and National Economic Research Associates (NERA). It details the results of a study to examine the issues surrounding the application of economic value-based pricing to a number of sectors and licence classes, under the provisions of the Wireless Telegraphy Act 1998. The sectors and licence classes considered are:

* Amateur and Citizens’ Band (CB);
* Aeronautical;
* Maritime;
* Fixed Satellite Services;
* Fixed point-to-multipoint services;
* Fixed Wireless Access (FWA);
* Test and Development licences (T&D);
* Programme Making and Special Events (PMSE)

This report presents the results of the study regarding the feasibility of introducing economic value-based pricing in each of the areas, and where appropriate calculates marginal values on which economic vale based prices should be based.

The information in this report is drawn from available literature, interviews with relevant RA staff and, where appropriate, interviews with personnel from other external organisations.

 

1.2 Economic value-based pricing

The objective of the Wireless Telegraphy Act 1998 is to base charges for wireless telegraphy licences on spectrum management considerations. That is to say, fees to install or use radio equipment should reflect more closely the value of spectrum instead of being tied to the fully allocated costs of spectrum management, as was previously the case. In previous reports, the new fees have been described as administrative prices. This is perhaps a little confusing, since in practice cost recovery based prices are also administratively set. To distinguish the two approaches more clearly, this report uses the term economic value-based pricing to describe fees set on spectrum management considerations.

Economic value-based prices are set at a level so as to influence the choices made by spectrum users, such that their use of and requests for spectrum reflects the value they place on it. Under such a regime, users (and potential users) have incentives to release unused or under-used spectrum, to consider alternative services or less congested frequency bands, and to implement more spectrally-efficient technologies.

The primary objective of economic value-based pricing is to improve the efficiency with which a scarce resource (the radio spectrum) is managed, not to raise money. The general principle we adopt is that such a move is only likely to result in benefits if it induces users to change their spectrum use. Although such changes are likely to be slow to occur, because of the significant investment in existing technologies and services, this is not an argument against the application of economic value-based pricing. The application of the existing administrative rules to clear spectrum or to introduce new more efficient technologies also takes many years to implement for exactly the same reasons.

It should be pointed out that a move to economic value-based prices is not limited to price increases, with the intention of encouraging more efficient use of bands or even the migration of users elsewhere. Prices of certain under-used bands may also be reduced, in order to encourage their increased use. This could be taken, for example, as a complementary measure to higher pricing in congested bands, in order to make migration more attractive to users. Care should be taken, nonetheless, that such low pricing of spectrum does not result in over-subscription to, or inefficient use of, the bands in question. There will also be a range of costs arising from the introduction of economic value-based pricing, which will need to be set against the benefits of more efficient use of the spectrum. These costs include the administrative costs of establishing and operating a suitable licensing and pricing framework and the enforcement costs of, for example, reducing illegal use and of policing interference. Such costs will arise, although perhaps to different degrees, in any system of spectrum management.

2. Suitability of candidate sectors for economic value-based pricing

2.1 Introduction and summary of suitable candidates

The following sub-sections present an assessment of the feasibility of introducing economic value-based pricing for each of the candidate sectors or licence classes. A summary of the findings is provided below.

Under the Wireless Telegraphy Act 1998, spectrum licence fees are to be based on spectrum management considerations for all sectors. The extent to which it is appropriate to apply economic value-based pricing may, however, vary due to a range of constraints which limit users’ ability to change their spectrum use in response to the new charges. The principal constraint is found to be where assignments are co-ordinated for international use, such that alternative uses of spectrum are limited or where changes to equipment used needs to be agreed internationally.

Table 2-1 summarises the suitability of the candidate sectors or licence classes for economic value-based pricing.

2.2 Approach

In order to assess the net benefit of a move from cost recovery to economic value-based pricing, we have qualitatively applied the checklist of criteria set out in Figure 2-1 to each of the sectors and licence classes under consideration.

    image001.gif (20444 bytes)

    Figure -1: Approach to assessing merits of economic value-based pricing

    The logic behind these criteria is as follows:

* Is there excess demand for spectrum either from existing users/uses or from alternative uses/users either now or in the foreseeable future? If the answer to all of these questions is no, then there is unlikely to be any merit in applying economic value-based pricing to ration demand, as demand can be satisfied on a first-come, first-served basis. Note that the relevant definition of excess demand in this case includes potential users not necessarily belonging to the user groups to which the spectrum is currently allocated, who might nonetheless be interested in using the bands in question. Thus, "congestion", in the context of this study, has a broader scope encompassing potential or latent congestion.

* Could spectrum use change in response to spectrum pricing? If economic value-based pricing were introduced, could or would existing or potential users take actions to change their spectrum use over time by, for example:

* using more spectrally-efficient equipment;
* adopting different, possibly non-radio based, alternatives;
* moving to different (non-congested) bands;
* sharing capacity with other users/applications?

In answering this question it is necessary to take account of the technical and commercial feasibility of possible alternatives.

* Are there other uses? Even if users have no alternative but to stop using the spectrum altogether, it is necessary to consider whether this would release spectrum for another application which could realistically use it, taking account of technical considerations and international co-ordination and allocation requirements. It is also possible that economic value-based pricing might lead users to take actions to press internationally for more efficient use of spectrum.

* Are there major policy/political impediments to changing prices? We would suggest that, ideally, economic value-based prices should apply to all users. Exceptions should be reserved for special situations, for example where there are reasons for change (eg the proposed UHF band reversal), and cases where the user genuinely provides social benefits which exceed their private benefits from spectrum use. Discounts might be argued on pioneer's preference grounds, for example, but again the grounds should be tightly specified to fit the economic or social justification for the discount.

* Is it feasible to administer spectrum pricing? A final test is the likely practicality of collecting licence fees and enforcing spectrum disciplines. If the introduction of higher spectrum licence fees is likely, for example, to result in an increased number of users attempting to evade payment and/or operating on an unlicensed basis and if the costs of enforcement are likely to be prohibitive, then there may be little merit in applying revised charges.

By testing each licence class against these criteria, it is possible to arrive at a conclusion about its suitability for economic value-based pricing.

2.3 Amateur and CB

2.3.1 Introduction

This section provides a summary of the current situation in the area of amateur and CB radio. This area is taken to include:

* Amateur Service;
* Amateur Satellite Service;
* Citizens’ Band (CB) Radio.

The amount of spectrum allocated to these services is summarised in the table below.

Service Frequency range Allocated spectrum
CB 26.965 – 27.99125 MHz 800 kHz
Amateur Services < 1 GHz 20 MHz
  < 100 GHz 1.5 GHz
  > 100 GHz 5 GHz
Amateur Satellite < 1 GHz 3 MHz
  < 100 GHz 1 GHz
  > 100 GHz 4 GHz

Table -2: Summary of spectrum allocated to Amateur and CB Services (Source: RA)

The spectrum is allocated to these services mainly on a primary basis below 1 GHz, whereas most of the higher Amateur and Amateur Satellite frequencies (beyond 1 GHz) are allocated on a secondary basis. All licences are issued by an outside contractor, Subscription Services Limited (SSL), who processes the users’ applications and issues the licences. Each licence is valid for a year. The majority of the secondary frequencies are shared with other users.

2.3.2 Use and Licensing of Spectrum

There are several types of licences as follows:

* Amateur radio licence: this covers both Amateur Services and Amateur Satellite Services. It authorises individuals to use the amateur spectrum provided they are qualified. The licence fee is £15 for each person aged 21 years or over and is free of charge for those under 21 years of age. This licence comes in 5 different classes:

* Class B Novice Licence: requires completion of a practical training course and a multiple-choice exam. Allows the user to access a restricted number of frequencies above 30 MHz in the VHF, UHF and SHF bands.

* Class A Novice Licence: requires completion of a practical training course, a multiple-choice exam and a Morse code test (5 words per minute). It allows the user to access a restricted number of frequencies in the HF, VHF, UHF and SHF band, including some below 30 MHz.

* Class B Full Licence: requires a more detailed multiple-choice exam. This allows users access to all amateur frequencies above 30 MHz in the HF, VHF, UHF and SHF bands.

* Class A Full Licence: requires a more detailed multiple-choice exam and Morse code test of 12 words per minute. This give the user access to all the frequencies allocated to the amateur services, including those below 30 MHz.

* Class A/B Full Licence: technical requirements as Class A, but only requires a 5 words per minute Morse code test.

* CB radio licence: this licence authorises any individual to use CB equipment and frequencies. Each licence costs £15. During the Autumn of 1999, the RA is going to introduce a free CB licence for the under 21’s. CB licences are issued on application, with no tests involved.

Table 2-3 summarises the types of licence together with the frequencies allocated to them, their price, and the estimated number of licences in January 1999.

Licence Frequency range Licence fee Number of licences
Amateur Various bands
(72 kHz – 250 GHz)
£15 47,156
Amateur (under 21) Same as Amateur Free 1,848
CB 26.965 MHz – 27.99125 MHz £15 41,722

 

Table -3: Amateur and CB Licences (Source: RA)

There are currently around 50,000 licensed radio amateurs, although this number is falling, probably due to the wider availability of mobile phones, PCs and the internet and perhaps because of a lack of new younger users to replace the ageing population of licensees. When CB was first legalised in 1981, there were approximately 300,000 licensed users. This number is still falling rapidly (there are now around 42,000 licences), not least it is thought because many continuing users feel it unnecessary to re-apply for their annual licences. This could be due to the lack of any real licence enforcement, as it is not necessary to possess a licence when buying CB equipment. There are plans to make CB licences free for under-21s, partly in response to these enforcement problems.

Both CB and Amateur services incur a loss for the RA. The main problem with CB is enforcement. Unlicensed users are believed to form a major part of the user base. Thus the costs incurred in enforcing licence regulations, combined with the everyday costs of administering the service, are higher than the revenue generated by the licences. The situation with radio amateurs is different. Here, the number of unlicensed users is negligible due to the station identification procedure operated by radio amateurs, the call sign for which is only issued with a licence.

2.3.3 Planned Changes

At the moment radio amateurs have to pass a Morse code test to obtain access to the HF band. This is an international requirement. However, negotiations are underway internationally to do away with the compulsory need to demonstrate a knowledge of Morse code as a prerequisite to using the HF bands. The RA and RSGB are working towards the introduction of an incentive based licensing structure and will implement new exams once the updated requirements have been agreed. The general structure of the licences will nonetheless remain.

2.3.4 Congestion

This section considers whether there is excess demand for the spectrum from actual or potential users of the spectrum (the scope for possible alternative uses of the spectrum is considered in the next section). In this sense, the concept of congestion used is intended to include potential or latent as well as current congestion.

CB
In CB radio there are many users sharing a few channels on a non-controlled basis. The amount of spectrum allocated to CB users is small, with users tolerating long delays and heavy localised interference. Illegal use is high, resulting not only in lost revenues for the RA, but also in localised interference for licensed users. Illegal users, often using too high a transmitter power can cause interference to other services including television reception in the local area. In fact, most of the costs of administering this service are incurred through policing activities. Such problems do, however, tend to be localised, and there is no real deterioration of the situation envisaged. Although it is claimed by the CB community that there is excess demand for spectrum amongst existing users, the RA have been unable to technically verify such congestion. Moreover, it is felt that an increase in the licence fee (the natural response to congestion) would result in nothing more than an increase in unlicensed use.

Amateur
The situation for Amateur radio is different, in that users have to pass various examinations to be allowed access to more frequencies. Also, as most of the frequencies are allocated on an international basis, with the harmonisation undertaken by the International Amateur Radio Union, congestion is quite high, especially in the frequency bands below 30 MHz. The amount of spectrum allocated to the amateur services in this frequency range is rather low, and is already shared with other users, like the MoD and maritime services. Due to its long propagation range, it is of little commercial value, indeed many alternative applications now make use of satellite communications.

The spectrum between 30 MHz and 10 GHz allocated to Amateur Radio is already shared, again mainly with the MoD. The frequencies in this range could be of interest to fixed and mobile services, in particular 430 MHz to 440 MHz. Beyond 10 GHz the frequencies are mainly used for amateur satellites. Spectrum used by those satellites could only be freed for other uses once the satellite service has ceased to operate.

2.3.5 Change Possibilities

This section considers the possible methods open to users for relieving congestion of the spectrum, and the scope for alternative uses or users of the spectrum taking into account technical factors and any international co-ordination issues that may apply.

What alternatives do users have?

There appears little scope for CB users to modify their spectrum use. Existing equipment is normally designed to operate only on the recognised UK and CEPT CB channels. Therefore, users could only migrate to other bands, assuming spectrum became available, by purchasing new equipment.

There might be some scope for amateurs to move to different bands if suitable, less congested, frequencies could be found. In contrast to CB, enforcement issues are unlikely to be a problem.

Possible alternative uses/users of the spectrum

For spectrum used by Radio Amateurs, there are possibilities that part of the allocation could be used by other groups. As was mentioned above, there are segments of the spectrum currently allocated to this service which could be used by fixed and mobile services. Furthermore, it would seem that there is some precedent for changing the bands available to amateur users, and this has not presented a serious problem in the past.

2.3.6 Policy Context

As well as international allocation agreements, which could affect the possibility of re-assignment of some bands currently used by Radio Amateurs, there are other policy constraints operating in this area. The RA’s priority in allocating spectrum to amateur radio is to encourage its wider use for educational, leisure and amateur research purposes. It is felt that the service represents a valuable source of ‘engineers of the future’ and should not be undervalued as such.

For CB, the cost of policing this service outweighs its revenue. This also means that, were the bands currently used by this service to be re-allocated to another service, the large number of users would make the task of freeing the CB bands very difficult. There is, moreover, little scope for persuading current users to buy more spectrally-efficient equipment, especially whilst such equipment is still relatively expensive and many CB users are unwilling even to buy a licence. Thus, in the case of CB, there is little scope for using spectrum pricing to encourage the use of less spectrum in this area.

2.3.7 Scope for economic value-based pricing

There are major practical and policy obstacles to the introduction of economic value-based pricing for either CB or amateur use. While congestion has not been technically verified by the RA, there is significant demand for the small amount of spectrum available from existing users and there is at least a theoretical possibility of alternative uses of the spectrum. In practice, however, unless a practical solution is found to enforce licence conditions and protect legitimate users from those that abuse the service, the introduction of such charging would appear self-defeating.

Spectrum pricing could play a role in relieving congestion in the amateur bands, and parts of the spectrum could be used by fixed and mobile services. There are, however, perceived to be wider social benefits from the encouragement of amateur use suggesting that there is a case for preferential treatment relative to other users. It is the RA’s policy to encourage the use of amateur radio in the UK, including the use of voluntary band plans.

2.4.2 Use and Licensing of Spectrum

Licence products

Aeronautical licences are available for a range of applications. All channels are assigned and approved by the Civil Aviation Authority (CAA). However, many mobile frequencies are determined by international agreements. A brief description of each licence is given below.

Aeronautical mobile communication: This covers:

* Aeronautical Ground Station (AGS): Licences differentiate between

* AGS (General): This licence covers air traffic control at airports. Users apply for a number of channels. These channels are protected, and only shared when no interference is possible.

* AGS (Glider, Hang Glider and Balloon): This licence allows the use of one of 9 channels to be used by ground stations responsible for the launch of gliders, etc to communicate with the aircraft.

* AGS (Special): This licence is for business use at airports; for example, airlines communicating with their aircraft, etc. There are 28 shared channels in the 117.975 MHz - 137 MHz frequency band.

* AGS (Special Mobile): This licence covers radio equipment used by the emergency and rescue services at airports. One channel in the 117.975 MHz - 137 MHz frequency band is set aside for this purpose.

* Aircraft: Licences available are Aircraft (Tier A, B, or C depending on an aircraft’s approved maximum take-off weight) and Aircraft (Glider, Hang Glider, and Balloon). These pre-packaged licences authorise the use of radio equipment and frequencies appropriate to UK registered aircraft. They are issued by the RA.

Aeronautical navigational aids (Navaids): This licence class covers radio navigation, radio location, radio altimeters, GPS, etc. It authorises the use of radio equipment on CAA agreed assignments.

Table 2-5 contains estimates for the user population of each of the various licences listed above. Each licence is valid for a year.

Table -5: Aeronautical Licences (Source: RA)


Licence awards
Except for aircraft licences, the RA only issue licences after the prospective user has submitted an application to the Safety Regulation Group (SRG) of the CAA. The CAA has control over the assignment of frequencies for each licence, under the Wireless Telegraphy Act 1949. The SRG ensures that the frequencies are interference-free and that all safety requirements have been satisfied. The application is then passed to the RA for approval. This is mainly a rubber stamp exercise for the RA.

The aircraft licences are issued directly by the RA, they do not require any frequency assignment since they consist of a pre-bundled set of frequencies. In future, to save administrative costs, the RA is considering transferring the process of distributing licences to the CAA. The current system of basing prices on the take-off weight of the aircraft, for what is effectively the same radio licence, appears to have no economic justification, since all of the aircraft involved have access to the same frequencies. A similar situation involving licences for ships of different sizes, was abolished in favour of a single licence, and there seems to be little reason why the same change should not be made in the case of aircraft.

Terrestrial Flight Telecommunications Systems (TFTS) is a special area within the aeronautical spectrum. 10 MHz in the frequency band between 1,670 MHz and 1,805 MHz is set aside for this service for administrations wishing to provide it. In the UK, BT has been licensed by the RA to offer TFTS for a five-year period. The licence fee is £1,350 per frequency and increases each year. BT currently uses 10 frequencies.


2.4.3 Planned Changes

Recently, the European Aviation Authorities have agreed to change, above Flight Level 245, the bandwidth of channels used in the frequency band between 118 MHz-137 MHz from 25 kHz to 8.33 kHz, thus effectively tripling the number of available channels. This change is due to be implemented in most European countries, excluding Britain amongst others, on 7 October 1999. The required change in radio equipment in all AGS and aircraft together with necessary training of staff is underway and should be completed on time. The CAA is keen to see these changes introduced in the UK as soon as possible. Furthermore, they would like to introduce 8.33 kHz channels at all flight levels due to the increasing demand.

2.4.4 Congestion

This section considers whether there is excess demand for the spectrum from actual or potential users of the spectrum (the scope for possible alternative uses of the spectrum is considered in the next section). In this sense, the concept of congestion used is intended to include potential or latent as well as current congestion.

Frequencies allocated to aeronautical mobile (HF and VHF communication) and used for air-to-ground communication and vice versa are heavily used and hence can become congested at times. This is exacerbated by the fact that these frequencies are used world-wide and demand is growing constantly. The spectrum is limited mainly because it cannot be shared easily. This is due to safety issues requiring that channels be protected and can only be shared if the operators are geographically separated and therefore do not interfere with each other's operation.

Due to the fact that two organisations are involved, a lack of information sharing can sometimes lead to inefficiency in the licensing process. One example would be an airfield operator going out of business, which would free the channels allocated to them for use by other users. However, the CAA will not be aware of this change unless the RA inform them because the CAA are not involved in the process of renewing licences. Therefore, they are not automatically aware that they are able to utilise these channels. Notwithstanding this, there have been no significant assignment problems to date. There are no refusals of applications for ground station or navaid licences on these grounds. Furthermore, there is no increase in applications foreseen which would change this situation.

The situation for navaids is less clear than for mobile communications. There is some congestion for particular systems such as the Instrument Landing System (ILS), where there is only a single frequency band (40 channels) available for all systems world-wide, and it is likely that the pressure on other systems such as Mode S radar will increase as the demand for data communications grows. Some primary radar frequencies are shared with other users, particularly the MoD and broadcasting assignments.

2.4.5 Change Possibilities

This section considers the possible methods open to users for relieving congestion of the spectrum, and the scope for alternative uses or users of the spectrum taking into account technical factors and any international co-ordination issues that may apply.

What alternatives do users have?

There is some scope for users to adopt more spectrally efficient equipment. The scope for change in the short term is, however, limited due to the need to agree changes internationally (see section 2.4.6).

Possible alternative uses/users of the spectrum

Much of the demand for spectrum in this area comes from other aeronautical users. Alternative uses of the spectrum are limited due to the international nature of the allocations.

2.4.6 Policy Context

At present, the RA makes a profit from aeronautical licence fees since all of the technical work associated with the issuing of licences is done on their behalf, free of charge, by the CAA. Perhaps not unsurprisingly, therefore, the CAA have expressed an interest in economic value-based pricing although this is probably on cost recovery rather than efficiency grounds.

The scope for meeting users' demands for spectrum through the use of more spectrally efficient equipment is limited by the need to agree changes to on-board equipment internationally. This is invariably a slow process, with due notice of 7 years required before any changes can be imposed.

Changing any of the internationally allocated frequencies cannot be considered as a feasible option in the spectrum pricing calculation. The emphasis should thus lie on making more efficient use of the allocated spectrum.

2.4.7 Scope for Economic Value-based Pricing

There is growing demand for aeronautical spectrum, however, the scope for administrative pricing to modify users' behaviour is limited by the international nature of the allocations and particularly the need to change on-board equipment. Any move towards the use of more spectrally efficient equipment will require international agreement, and is probably best sought through lobbying rather than any unilateral pricing initiative by the UK authorities. It does appear, however, that some efficiency gains might be achieved through better co-ordination between the RA and the CAA.

TFTS is a special case which is more akin to public telephony systems than aeronautical use. There are national operators in each country, so it would be possible to charge them for their use of spectrum possibly applying the same level of pricing as in neighbouring bands (ie fixed links at 1.5 GHz).

2.5 Maritime

2.5.1 Introduction

This section provides a summary of the current situation in the area of maritime radio. This area is taken to include:

* Maritime mobile radio;
* Radiodetermination.

The amount of spectrum allocated to these services is summarised in the table below.

Table -6: Summary of spectrum allocated to maritime services (Source: RA)

2.5.2 Use and Licensing of Spectrum

Licence products

Maritime radio use covers a range of applications. A brief description of the typical usage in each area is provided below.

Maritime mobile radio: This covers:

* Ship radio: This pre-packaged licence allows the user to install maritime radio equipment on a ship station and use the maritime spectrum. It was rationalised to one single fee in April 1998.

* Transportable radio: This pre-packaged licence allows the licensee to use a portable maritime radio on more than one vessel.

* Coastal Station Radio (CSR): These licences authorise coastal stations or systems to use internationally agreed maritime spectrum and UK maritime business channels. The applicant requests a specific licence and, if necessary, a number of channels. The RA then issues the licence and assigns channels on a regional basis in order to minimise interference with other regional users.  This class of licence comes in three versions:

* CSR (Marina): This licence is designed for sailing clubs and marinas using the radio for berthing and race control.

* CSR (International): This customised licence is designed for port operations and is charged on a per channel per base station basis. The channels allocated are internationally agreed maritime VHF channels in the 156 MHz – 163 MHz band.

* CSR (UK): This customised licence allows businesses to communicate with ship stations from coastal stations. The licence is charged on a per channel per station basis. There are 40 channels for pre-set uses in the 156 MHz – 163 MHz band.

Radiodetermination: This licence covers navigational aids or radar stations. It authorises the frequencies for specific navigational stations.
Frequency usage

The frequency range allocated to each of these uses at present and estimates of current user population are detailed in Table 2-7. Each licence is valid for a year.

Table -7: Maritime licences (Source: RA)

All maritime frequencies are allocated through international agreements, except for CSR (UK), which is allocated by the RA.

2.5.3 Planned Changes

Channels dedicated solely to safety and distress, emergency, safety and routine calling suffer frequent and widespread misuse. The recently introduced GMDSS uses dedicated distress alerting channels utilising digital signalling. This can be viewed as an example of a move to better spectrum efficiency. However, whilst GMDSS compatible radio equipment is compulsory onboard large commercial/passenger vessels, its use onboard pleasure vessels is voluntary. The RA is actively encouraging its adoption by leisure craft users. It is intended that eventually all vessels fitted with radios will be compatible with GMDSS.

Coast stations operated by BT for public correspondence are to be closed down in the near future freeing some spectrum in the MF/HF frequency range. The RA is in the process of deciding what use to make of this spectrum when the closure is announced. However, this spectrum will continue to be used for maritime purposes.

2.5.4 Congestion

This section considers whether there is excess demand for the spectrum from actual or potential users (the scope for possible alternative uses is considered in the next section). In this sense, the concept of congestion used is intended to include potential or latent as well as current congestion.

The use of maritime radio frequencies assigned to CSR (International) is very high especially in the Thames Estuary area and along the Solent, as many licensees share the same channel and hence encounter interference. The situation is similar for the licence CSR (Marina) channels. The channels assigned to the licensee are not exclusive and are subject to heavy traffic. Furthermore, interference from port operators on the continent is also experienced. CSR (UK) spectrum also experiences significant congestion.

In general, navigational aids have not suffered from any interference or congestion. The only exception is for DGPS VHF and DGPS MF/Low HF where users have been refused licences due to congestion and possible interference.

2.5.5 Change Possibilities

This section considers whether there is excess demand for the spectrum from actual or potential users of the spectrum (the scope for possible alternative uses of the spectrum is considered in the next section). In this sense, the concept of congestion used is intended to include potential as well as current congestion.

What alternatives do users face?

Over the longer term, it is likely that the introduction of newer, more spectrum efficient equipment including narrowband systems, will provide a means for relieving congestion and possibly freeing spectrum for other uses. The scope for achieving this through the unilateral introduction of higher licence fees in the UK is, however, limited by the need to agree technologies and to co-ordinate allocations internationally. A possible exception arises in the case of CSR (UK) since the RA has direct control over the assignment of these frequencies, and they are used exclusively through UK coastal stations. The feasibility of introducing 12.5 kHz or 8.33kHz channel spacing should be considered.

Possible alternative uses/users of the spectrum

The major alternative use for the maritime spectrum is for land mobile purposes (the maritime band sits alongside the land mobile allocation).

 

2.5.6 Policy Context

All maritime frequencies are allocated on an international basis (except for CSR (UK)). Changing this allocation for any of the internationally agreed frequencies cannot, therefore, be an option in any UK-specific spectrum pricing exercise. Furthermore, any attempts to influence the take-up of newer, more spectrum-efficient equipment would have little effect on other, world-wide users of Maritime frequencies. In addition, changing the amount of spectrum used by UK licensees would not make any of the internationally-allocated Maritime spectrum usable by other services. Finally, any attempt on the part of the UK authorities to influence the behaviour of UK-registered Maritime licensees through the changing of licence prices or conditions could simply result in users registering their vessels elsewhere, which would have no effect on the use of frequencies and would place control out of the hands of the UK authorities. Thus, unless there is an international agreement to introduce new technologies or spectrum pricing, a unilateral approach by the UK will not bring about any changes.

A further problem is the lack of enforcement. There are about 120,000 registered vessels in the UK, but only 60,000 issued licences. However, it must be remembered that the use of radio on pleasure vessels is voluntary and users of pleasure vessels who have a radio are not always aware of the need for a licence to operate it.

Furthermore, even though the administration of the ship radio licences is contracted out (£6 of the £22 licence fee is retained by the contractor who deals with vessel call signs and notification of international authorities), the RA still deals with a large number of queries and other non-routine administrative tasks.

2.5.7 Scope for Economic Value-based Pricing

Ostensibly, maritime appears to be a prime candidate for economic pricing since there is considerable congestion and high demand. Whether in the long-run the more efficient solution is to move to more spectrally efficient equipment or to allocate more spectrum to the service is a question which would be easier to answer and achieve if the spectrum were properly valued. In practice, these are issues which lie outside the control of the UK since technologies and allocations need to be agreed internationally. Higher licence fees in the UK, might simply lead to users registering their vessels elsewhere and could further add to the current enforcement problems. It therefore appears that there is little benefit to be derived from the UK unilaterally introducing administrative pricing for most of the maritime band.

A possible exception is the case of CSR (UK), which is under direct UK control and for which spectrum pricing might play a role in relieving congestion if a practical solution to the problem of enforcement could be found. Since most of the spectrum sits alongside the land mobile allocation, there appears a strong case for aligning CSR (UK) prices with that of PBR.

2.6 Fixed satellite

2.6.1 Introduction

This section provides a summary of the current situation in the area of fixed satellite links. The area is taken to include:

* Permanent Earth Stations;
* Transportable Earth Stations;
* Very Small Aperture Terminals (VSATs);
* Miscellaneous Earth Stations.

The amount of spectrum allocated to these services is summarised in the table below.

Table -8: Summary of spectrum allocated to fixed satellite services

2.6.2 Use and Licensing of Spectrum

Licence awards

For fixed satellite services (FSS), the frequency spectrum requirements are identified by the satellite operators and then co-ordinated within the ITU framework using Appendix S8 (formerly Appendix 29) to determine the satellite payload before launch. However, only satellite uplinks (Earth-to-Space) are licensed in the UK

Satellite uplinks have to be licensed and a total of about 22 GHz of spectrum has been allocated to them in the frequency range from 5 GHz to 105 GHz. Since international co-ordination can take a long time, which might be unacceptable to the satellite operator, the RA can issue a licence on a non-interference basis before all the necessary regulatory requirements have been fulfilled, with the understanding that the licence will be revoked if interference occurs.

Licence products

The following licences can be obtained:

Permanent Earth Station: This licence is intended for permanently installed earth stations operating to satellites in the geostationary orbit. Full site clearance and national and international co-ordination procedures apply to provide maximum protection to the earth station. The licence comes in three different classes:

* Class I: stations with a required RF transmission bandwidth not exceeding 100 kHz;
* Class II: stations with a required RF transmission bandwidth not exceeding 2 MHz;
* Class III: stations requiring RF transmission bandwidths above 2 MHz.

Transportable Earth Station: This licence category covers all transportable earth station applications; for example, satellite news gathering, televising sports events, etc. This application is characterised by a short-term requirement to provide uplinking from a location that is often determined by external factors, ie a news item. Due to time constraints, only a minimal national clearance procedure must be carried out prior to operation.

Very Small Aperture Terminal (VSAT): This licence enables the licensee to operate a number of VSATs in a network. The only condition is that the uplinks are confined to the exclusive frequency bands between 14.0-14.25 GHz and 29.5-30 GHz to facilitate minimal co-ordination of the VSATs.

Miscellaneous Earth Stations: This licence is intended to apply to special or unique applications that do not fall within the scope of the other three licences. Examples would include earth stations involved in tracking, telecommand and control operations, transfer orbit missions, short term single event operation, etc. The authorisation to operate is relinquished once the specific operation has been completed.

Table 2-9 summarises the types of licence, together with the frequencies allocated to them, their prices, and the estimated number of licences. All licences, except for the miscellaneous earth station licence, are awarded for the duration of 1 year and are awarded on a first-come-first-served basis.

2.6.3 Planned Changes

One of the main areas of growth within FSS over the next 10 to 15 years is expected to be small terminal traffic. The start of this trend has been demonstrated by the recent growth in the number of VSAT licences. The effect of this growth is that the UK now has one of the largest two-way (transmit and receive) VSAT networks in Europe (mainly due to the lottery operator Camelot).

Another area of growth is services operating in the 20/30 GHz band. The ITU has received notifications for satellite networks using both geostationary and non-geostationary orbits for services to small aperture interactive terminals. ETSI is currently formulating standards for these terminals with the possibility of interactive services being operational at the beginning of 2000. The successful implementation of these systems could lead to the use of hundreds of thousands of terminals throughout Europe and the rest of the world. This would be likely to result in sharing difficulties in the shared bands if such high density FSS terminals were to operate using the same frequencies as high-density fixed services. These sharing issues are the subject of ongoing work in CEPT and the ITU.

2.6.4 Congestion

This section considers whether there is excess demand for the spectrum from actual or potential users of the spectrum (the scope for possible alternative uses of the spectrum is considered in the next section). In this sense, the concept of congestion used is intended to include potential or latent as well as current congestion.

At an international level the ITU provides co-ordination procedures to identify suitable spectrum for particular satellites in particular countries. The aim of the co-ordination procedure is to ensure that once the frequencies have been identified, an operator does not suffer any interference from other satellite operators. Due to the ever increasing development of FSS notifications there is a high demand for orbital locations and spectrum, particularly in the lower FSS bands. This has resulted in an over filing of applications for orbital resources within the ITU, so-called ‘paper satellites’, and co-ordination difficulties can sometimes mean that operators have to operate at frequencies that are different to those for which they originally applied.

The UK has led the de-regulation of satellite user terminals. Consequently, there is quite a high number of satellite earth stations in this country. There is so far no congestion in the sense that operators have been refused a licence because not enough spectrum was available.

There is, however, a high degree of sharing between FSS and terrestrial fixed links. Co-ordination areas for each Earth station can be quite large (up to a radius of 350km). This area is not sterilised, but requires careful co-ordination with other users, eg terrestrial fixed links, to minimise interference and provide suitable assignments. Interference patterns depend on the location of the satellite and the characteristics and location of the Earth station; for example, larger dishes create less interference due to higher gain, but they can also be more sensitive to interference. Satellite operators can reduce the interference from terrestrial fixed links by providing sufficient shielding for their equipment. This, however, adds to the overall cost of the earth station. Some operators using receive-only equipment (which does not require
