Radio Communication In Tunnels

To conform to the latest safety legislation, radio users working on large construction projects must be able to communicate in an emergency from anywhere on-site. Full radio coverage is obligatory, whether employees are working at ground level, or within deep tunnel space.

Brentwood supplies advanced two way digital radios, and repeater units. This means your radio communication system has the ability to overcome the most awkward terrain, both above and below ground. For example, we often use Motorola DR3000 repeaters, which have the ability to improve and expand radio coverage at all times in the harshest conditions. Once they receive the incoming radio signals, they’re able to broadcast them at a higher wattage without delaying the transmission.

We strategically position the repeater units throughout the site and interlink them using cables. This arrangement boosts the radio transmissions uniformly across all levels, including underground. Here we enhance coverage by skilfully placing repeater antennas along the length of the tunnels.
Perfect reception across all working areas means any radio user can send an alarm in an emergency using their two way radio.
