FIELD: information technology. ^ SUBSTANCE: first transmitting device and second transmitting device recognise an operating channel and a group of standby channels from communication cannels between two devices. The first transmitting device selects a measuring channel from the group of standby channels and sends a test signal over the measuring channel to the second transmitting device. The second transmitting device uses the test signal to measure communication quality, records measurement data and sends the test signal bearing the measurement data over the measuring channel to the first transmitting device. The first transmitting device records the measurement data contained in the test signal from the second transmitting device, uses the test signal to measure communication quality and records these measurement data. The first transmitting device selects a new measuring channel from the group of standby channels and sends a test signal bearing these measurement data over a new measuring channel to the second transmitting device. ^ EFFECT: shorter time for switching channels between transmitting devices. ^ 10 cl, 8 dwg |
