Short Range Business Paging: Notes for Radio Suppliers and Manufacturers |
This information sheet provides information to radio suppliers and manufacturers on Short Range Business Paging (SRBP) (Short Range Business Paging Service: Notes for Users). This information sheet is also available to users who require more detail on SRBP.
SRBP is a short range paging service for business use providing one-way paging. It provides the user with flexibility to use his or her paging systems throughout England, Scotland and Wales without needing to give notice to the Agency or await an individual channel assignment. However there is no planning of the use of the SRBP channels and no Agency involvement in co-channel sharing or co-channel interference problems. SRBP channels may be busy and unusable at particular locations and times. SRBP is intended for the user who is prepared to accept its disadvantages along with its advantages. It is not suitable for users who need to be certain that access to a channel is and will remain available.
An SRBP licence allows the licensee to use 461.3000 MHz subject to complying with licence conditions. Maximum transmitter power allowed is 500 mW erp. The channels may be used anywhere in England, Scotland and Wales. The channels are shared by other users and in some areas especially where population and business activity is high the channels may become busy and at times congested. Customers may notice channels in urban areas becoming increasingly crowded after they have started using SRBP. This is a natural development due to increased use with an unplanned service. Customers may also experience interference from France on a few days each year.
An SRBP licence allows the licensee to use 461.3000 MHz subject to complying with licence conditions. The channel is of 121/2 kHz width. Maximum transmitter power allowed is 500 mW erp near 461 MHz. The channel may be used anywhere in England, Scotland and Wales. Paging transmissions are usually short and it is not expected that users will experience sharing difficulties. In areas where several users share one channel, address coding or channel sensing or an alternative may give better performance by increasing reliability. The Radiocommunications Agency will pursue extending the SRBP service to Northern Ireland, although this will need different frequencies.
Some manufacturers and radio suppliers have formed a forum to promote SRBP. The On-Site Communications Association is interested in the SRBP service. It is not necessary to be a member of these bodies to make or sell SRBP radios.
Equipment for the SRBP service should be type approved to MPT 1305 (near 461 MHz).
The equipment used on the paging service will need to meet EMC regulations. The pagers may not be connected to a telephone system.
In all cases users are required to meet licence conditions which include a limit on transmitted power and use of type approved equipment.
There is no guarantee the channel will be or will remain useable at any given location. Users who require protected paging use with Agency assistance in resolution of interference or channel-sharing disputes should consider whether their needs would be better served by paging alternatives i.e. Radiopaging (Standard), Local Communications, and Private and Public Wide Area Paging.
The Agency will change all existing PMR parking and demonstration licences, and will issue future licences, so that they allow a customer of a supplier with such a licence to use SRBP immediately after purchase for a short time while his or her own licence application is being processed. Demonstrations will also be permitted.
SRBP is an unprotected service with unplanned sharing of the paging channels and the Agency is not able to become involved in channel-sharing disputes between SRBP users. Enquiries should be referred to:
