Retevis tunnel radio communication solutions
Humans have never stopped on the road to transforming nature. Many super projects are under construction. Cross-mountain tunnels, subway tunnels, and undersea tunnels play a very important role. The depth of the most submerged subway tunnel is also around 20m. Wireless communication between underground workers and ground staff is especially important. It is a necessary equipment for project management. Retevis tunnel radio communication solutions came into being.
In Tunnel construction, Subway line, Road tunnel, Railway tunnel, Tunnel excavation, because radio communication needs to complete underground and above-ground communication work, due to the limitations of the underground area space and the particularity of the underground communication environment, the desired Special tunnel radio communication solutions to meet the needs of communication, it is different from normal pure ground communication.
Retevis tunnel radio communication solutions scheme：
Retevis tunnel radio communication solutions consists of radio repeater and handheld sets, the rrepeater station signal is processed by the power divider. Divided into 2 signal sources. A signal connects the internal antenna of the tunnel. Another signal is connected to the ground antenna. Two antennas work at the same time. It can receive signals inside the tunnel and also receive terrestrial radio signals. It is forwarded simultaneously inside the tunnel and on the ground. Let the tunnel and ground personnel communicate freely.
The repeater we recommen Retevis RT92 IP Networking Repeater, which can connect 3 repeaters via the network. Form the network. Radio communication is possible without geographical restrictions.
Retevis tunnel radio communication solutions topology:
Retevis tunnel radio communication solutions advantages:
*Support P2P network transmission, communication is not geographically restricted.
*DMR Digital Repeater, low system cost.
*Support digital voice encryption, communication is more secure.
