2023 – Israel Projects. We successfully carried out 3 larger projects for an Israeli customer. These included technology delivery for indoor and underground areas coverage with a radio signal in 160MHz and 700MHz frequency bands. Due to the greater number of transmitted services and their mutual frequency proximity, the development of associated circuits that would ensure sufficient mutual isolation of individual systems was a big challenge. Two of the mentioned projects will continue in the following years when additional technology should be delivered to expand the current coverage area.

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.



The information about our implemented and on-going projects of tunnel systems you can find on the page References – radio connections in tunnels.
