Method for radio transmission in a hazard detection system

摘要

In the case of bidirectional radio connections between secondary stations (S1, S2, S3, S4) and main stations (M) of a radio hazard detection system, so-called fading holes, which occur as a result of interference, can lead to impairments in radio traffic. DOLLAR A According to the invention it is provided that the transmitting and / or receiving antennas of the main station (M) and / or the unreachable secondary station (S1) are influenced, since this changes the propagation relationships between the main station (M) and unreachable secondary station (S1) and thus a fading hole is overcome.
