SELECOM equips Cave of Niaux with a Private DMR network
The French cave of Niaux, one of the most beautiful ornamented caves open to the public, trusted SELECOM for the installation and the putting into services of a DMR private system of radio communication.
To insure underground tourism protection, but also to guarantying personal security during interventions, Ariege country council entrusted Selecom for the supply, the installation and the commissioning of a new system of communication, relaying the indoor telephone network of Niaux Cave, and especially in all the galleries utilized by public, around 1000 meters.
With thermal and environmental constraints, SELECOM choose its OPTIREP 400 MHz. The deployed solution is composed of:
- A cabinet 19”;
- A DRM/phoning interface relay;
- An optic rack for monitoring;
- 3 FO-RF OPTIREP® 400 MHz remote repeaters (24 dBm for repeaters located at the gallery tips and 37 dBm for the central repeater);
- Omnidirectional and directional antennas ;
- DMR mobile radios 4RP indoor and outdoor of the cave.
