Coverage Enhancement
Standard radio systems may begin with only a few handheld radios and this type of system can be very effective when only an on-site, e.g. 1km radius, service area is required and where there are few obstructions to radio signals within the site. These handheld systems typically operate on a single-frequency channel with the option of adding channels if multi channel or private communications is required.
However, adding radio channels may increase the licence fee (if required) but we can advise whether the existing handhelds may be updated to enable user groups to operate on the original channel without each group overhearing the other group(s) and also assist with the application to Ofcom for new radio licences or changes to existing licences, e.g. additional channel(s). The administration for this service is offered free of charge to clients.
If obstructions to handheld signals cause unacceptable dead spots within the service area it is recommended that the radio system is updated to include a repeater station. A basic repeater system operates with 2 frequency channels where one frequency is used by the handhelds to transmit to the repeater and the second frequency is used by the repeater to automatically retransmit to the remaining handhelds. The repeater’s antenna is typically mounted at a high point near the centre of the service area where the type of antenna will depend on where the users are located within the service area.
A poor or incorrect antenna or a change in the concentration of users may result in poor system coverage. Wall to Wall Radio Communications offers comprehensive site surveys to establish the best type of antenna to be used. Typically, a high-gain antenna may be recommended where good coverage is also required at the periphery of the service area. Alternatively, a down-fire antenna may be recommended where the main users are within a tall building below the antenna site. 
When a repeater system has the optimum antenna but there are still coverage problems then a second antenna, connected in parallel with the original, may be required. The site survey would identify the cause of the poor coverage and recommend the type and location of a second antenna.
Systems that have good coverage of the service area but are experiencing traffic congestion may require an additional radio channel. Wall to Wall Radio Communications can advise on this option and assist with the application to Ofcom for an additional channel, if required for this specific purpose.
Repeater systems that require their service areas to be widened, perhaps to enable vehicular mobile radios to be used many km from the existing area, may require a change to the original antenna setup and are likely to require an increase in the licensed transmitter power and the site survey would identify the necessary changes to the system to enable wide-area coverage.
Additionally, repeater systems, both on-site and wide-area, can be linked so that a user transmitting at one site can be received at other sites. Wall to Wall Radio Communications bespoke systems advisors can advise on the various methods of achieving this.
