Abstract
1. A radio network for the transmission of information between a respective pair of several pairs of radio stations by way of a radio channel of n radio channels operated in frequency multiplex, wherein the transmitting sections of each pair of radio stations include means which transmit an individual security code before a transmission, and the receiving sections of the radio stations include means which only respond to this security code, characterised in that the radio stations (10, 11) of each pair of radio stations are designed in such a way that they stipulate and store n1 < n free radio channels (K1 ...) at least before the first time they are put into operation, that at least one station of each pair of radio stations is designed in such a way that the receiving section (15) is only switched on for predetermined testing times (tPR ) interrupted by interval times (tPA ) of equal length for the purpose of testing the n1 radio stations for their occupied state, and that the interval times are a multiple of the testing times.
