The study estimated the risk of interference into breathing apparatus telemetry systems operating at 862.9625 MHz used by the Fire and Rescue Services (FRS) in the UK. The work undertaken fell into two parts; in the first part laboratory testing of breathing apparatus telemetry systems was undertaken to establish relevant interference limits while the second[…]
