Fixed terrestrial links

Fixed Terrestrial Links or Fixed Wireless Systems (FWS) refer to terrestrial based wireless systems, operating between two or more fixed points. Using mainly digital technologies, directional antennas and typically operating at very high levels of propagation availability fixed terrestrial links are used to provide network infrastructure and customer access applications across a wide range of frequency bands, currently ranging from 450MHz to 86GHz.

Mobile Data Strategy and future use of 3.6GHz to 3.8 GHz

Please note our ongoing work on our mobile data strategy. Our strategy considers the challenges that rapidly growing demand for mobile data services could raise and what this may imply for Ofcom's work over the coming years. In particular, we identify and prioritise a number of spectrum bands where we are undertaking further work regarding their potential future availability for mobile data use, whilst recognising the many other competing demands for spectrum. Our statement was published in May 2014.

We updated our strategy in June 2016 (PDF, 363.4 KB) to take into account new developments such as developments in 5G technology.

Update: 2 February 2018

In October 2017 we commenced the statutory process to propose revocation of fixed links licences in the 3.6 to 3.8 GHz band. Our update on the timing of spectrum availability (PDF, 367.6 KB) provides an update on the decisions we have taken as part of that process.

Update: 6 October 2016

We have published a consultation document Improving consumer access to mobile services at 3.6 to 3.8 GHz. If you are considering applying to use the 3.6 GHz to 3.8 GHz band, please read Section 10 of this consultation document (PDF, 598.5 KB) for an explanation of how the availability of assignments in this band may change in the future and some interim measures applicable from the date of this consultation.

Update: 5 April 2017

Following the publication of our Update on 5G spectrum in the UK (PDF, 2.9 MB), applicants for fixed link licences in the 26 GHz band are advised to take note that the 26 GHz band has been identified by the European Radio Spectrum Policy Group (RSPG) as a pioneer band in Europe (and wider) for 5G (RSPG Opinion on spectrum related aspects for next-generation wireless systems (5G)). The UK supports this action and is currently working in CEPT to respond to the recent European Mandate on the technical harmonisation measures for this band. As indicated in our 5G update Ofcom is planning to consult in the coming period on options to make some or all of this spectrum available for mobile. Applicants of fixed links are therefore advised to take this into account in any future applications for this band and where possible may wish to consider alternative fixed link bands to meet their requirements.

Ofcom has today made new narrow channel options available within 2 X 14MHz of spectrum in the existing upper 6GHz frequency band. These new channels provide options where lower capacity connectivity is required and are available for assignment as part of Ofcom’s standard fixed link application and assignment approach. Further details of the channels available and technical conditions can be found in OFW446 (PDF, 1.4 MB).

Update 9 December 2019: New 8 GHz band available for fixed link assignment

Ofcom has opened additional spectrum in the 8 GHz band for assignment to fixed links as part of Ofcom’s standard application and assignment approach. This new spectrum, which forms part of the Public Sector Spectrum Release Programme, represents up to 2 x 84 MHz of duplex spectrum within the 7.9 to 8.4 GHz band on a shared/coordinated basis with the Ministry of Defence.

Further details of the channels available and technical conditions can be found in OfW 446: Technical Frequency Assignment Criteria for Fixed Point-to-Point Radio Services with Digital Modulation (PDF, 1.4 MB).

See our guidance for 8 GHz applicants (PDF, 300.1 KB).

Update 2 September 2019: 70/80 GHz band

Ofcom has recently updated (increased) the number of channels available for assignment in the Ofcom co-ordinated part of the 70 / 80 GHz band. The update, which makes the full 2 x 2 GHz of spectrum available for assignment, allows for the additional channels to be automatically considered for all licence applications in line with our current assignment policy. Further details of the channels available can be found in OfW 446 (PDF, 1.4 MB).

Update 16 May 2019: 1492 – 1517 MHz band

Licensees of fixed links in the 1.4 GHz band are advised to note the adoption and publication of EU Decision 2018/661 harmonising the 1492 – 1517 MHz band for downlink-only wireless broadband use across the European Union. To start the process of implementing this EU Decision, Ofcom has:

closed the 1498.5 – 1517 MHz and the 1356.5 – 1375 MHz band to new fixed wireless link applications and technical variations on 5 January 2019 as indicated in our fixed wireless services review statement;
today written to all licensees who hold 1.4 GHz fixed link licences to notify them of Ofcom’s proposal to revoke all 1.4 GHz fixed link licence(s) on 31 December 2022 for the purpose of securing compliance with EU Decision 2018/661. Licensees holding 1.4 GHz fixed link licences have 1 month (until 17 June 2019) in which to respond to Ofcom’s notice with any representations should they wish to do so.

Update 27 November 2018: 64-66 GHz

As indicated in our fixed wireless services review statement, we have decided to change the authorisation in this band to licence exempt under new technical decisions (which are set out in updated Interface Requirements, IR 2030 and IR 2078). To implement this decision, we have made new regulations which came into force on 27 November 2018. Equipment complying with the new technical conditions will no longer require a licence to operate in the 64 - 66 GHz band.

Technical information

The construction of tall structures, including wind turbines, may impact on wireless services including wireless links or domestic broadcast reception. More information on these effects is available in an Ofcom guidance document, Tall structures and their impact on broadcast and other wireless services (PDF, 149.3 KB)

Wind farm co-ordination policy

When we are notified of a proposed windfarm, we will check to determine whether any part of that windfarm falls within 500 metres of the path between the terminals, or the terminals themselves, of any fixed link system operating above 1 GHz.

For scanning telemetry links, notifications will be forwarded on to CSS and JRC who will check whether any part of the windfarm falls within 1 kilometre of the path between the terminals, or the terminals themselves, of a fixed link system operating between 450 to 470 MHz.

If either check is positive, then we will inform the notifier that the windfarm proposer must liaise with the appropriate fixed link system operator(s).

Fixed Wireless Links and Scanning Telemetry Coordination

In relation to fixed wireless links (above 1GHz) and scanning telemetry links, Ofcom currently offers a coordination service for windfarm developers and planning authorities:

When we are notified of a proposed windfarm, we will check to determine whether any part of that windfarm falls within 500 metres of the path between the terminals, or the terminals themselves, of any fixed link system operating above 1 GHz.
For scanning telemetry links, notifications will be forwarded on to CSS and JRC who will check whether any part of the windfarm falls within 1 kilometre of the path between the terminals, or the terminals themselves, of a fixed link system operating between 450 to 470 MHz.
If either check is positive, then we will inform the notifier that the windfarm proposer must liaise with the appropriate fixed link system operator(s).

Developers and planning authorities wishing to submit coordination requests should e-mail details of proposed wind turbine locations to:Spectrum.Licensing@ofcom.org.uk

Enquiries will be forwarded to Ofcom’s Spectrum Assignment & Coordination team for civil microwave fixed links clearance; we also forward the enquiry to Atkins Telecommunications and Joint Radio Company Ltd. (JRC) for scanning telemetry clearance.

Domestic Television Reception

Ofcom cannot offer assessments of the potential impact of proposed windfarms or other tall structures on domestic television reception.

Viewers who are concerned about the impact of an existing or proposed windfarm on their television reception should contact their local planning authority or the developer of the windfarm. More information about the options open to developers and planning authorities to mitigate the effects on windfarms on television reception are available in the Guidance document below.

Industry groups

Ofcom’s Fixed Wireless Services (FWS) team runs a number of industry groups, promoting the use of the spectrum and facilitating spectrum trading. They aid direct communication with industry, designing a forum to exchange knowledge, ideas and analyse new concepts. They help FWS achieve its main goal which is to balance many competing objectives such as maximising spectral efficiency, flexibility of use for users, market demands and more.

Ofcom and industry members are given the opportunity to discuss market issues together, exchange ideas and share feedback on current projects concerning the management of the fixed wireless spectrum.

Attendees benefit from gaining increased knowledge and understanding of industry issues. More specifically, they are used for improving services and products, building relationships and improving problem-solving.

The groups are valuable opportunities for Ofcom and industry members to interact with each other directly, develop a more thorough understanding of each others’ working methods and priorities. Ofcom find it increases customer confidence which helps to identify and discuss key issues and subsequently lead to developing mutually beneficial solutions.

The industry groups for FWS are:

Fixed Wireless Industry Liaison Forum (FWILF)
Fixed Wireless Technical Review Task Group (FWTRTG)
Working Parties (WP)
Fixed Service Task Group (FSTG)

Fixed Wireless Industry Liaison Forum (FWILF)

The FWILF is the main forum. Usually meeting twice a year, it updates members on the latest developments in current technical and market issues and coordinates the events of the other groups. If you wish to gather an overview of recent developments to improve the spectrum efficiency for fixed wireless services, trading policies and general issues that will potentially affect the whole of the industry, than it is best to attend this forum.

FWILF Members Area

Fixed Wireless Technical Review Task Group (FWTRTG)

FWTRTG is a sub-group of the FWILF. A smaller group, this discusses technical issues in detail. The group is used as a facilitator to report on the progress of technical projects being run by Ofcom and members of the FWILF.

Working Parties (WP)

These are small project teams that investigate specific issues raised in the FWILF whether technical or otherwise. They aim to derive possible solutions. The WP reports to the FWILF.

Fixed Service Task Group (FSTG)

This is another sub-group of the FWILF which assembles the scientific community to explore and solve propagation and planning issues raised by industry members at the FWILF. The group offers a chance to discuss ideas and issues with members possessing in-depth technical knowledge and a high level of scientific radio expertise.
