Radio channel application in the network for nuclear-physics researches

The development problems of the computer network ''Discret'', the commutation system of which is based on stack broadcasted radio communication, are reported. The network is created to investigate regional computer network design parameters and provide communication of data acquisition and processing system for nuclear physics researches with a computer centre located at 15 km away. The user 3W transmitters are based on the frequency synthesizer circuit with power amplification receivers according to the superheterodyne with circuit single frequency conversion. Frequency modulation is applied in the network. Reverse time (reception-transmission change-ovea about tens μs is provided by using the pin-diode circuits. The data transmission rate is up to 105 bits/s. Coverage area is 8x103 sq.m. with the transmission validity not worse than 10-6. The experimental network operation confirmed the correctness of accepted architectural and technological solutions
