Development - Tunnel systems

tunnel systems

RCD Radiokomunikace produces its own construction system called DS which is designed for radio coverage of roads and railway tunnels. The system enables the distribution of simplex and duplex radio signals in frequency band from 30MHz to 3GHz according to customer requirements. Depending on the length and the route of a tunnel, the radio signals are emitted with the help of radiating cables or antennas. Repeaters and amplifiers systems at the longer distances are usually connected with the help of optic fibres. If the distance is short it is carried out with coaxial cables. The entire system is monitored from the central office.
