The TETRA Fiber Optic Cellular Repeater is designed to solve problems of weak mobile signal in such place:far away from the BTS (Base Transceiver Station) and has fiber optic cable network underground.
Main Functions:
1,No more self-oscillation and easy to choose installation location;
2,For Cable-Access type,pure BTS signal picked up by the Donor Unit will greatly reduce the signal noise;
3,Omni-directional coverage antenna can be adopted to expand more coverage;
4,Adopting WDM (Wavelength Division Multiplexing) module to realize long-distance transmission;
5,Stable and improval signal transmission quality;
6,Max transmission distance between Donor Unit and Remote Unit is 20KM;
7,Easy to install on wall or pole;
Typical Application:
To expand signal coverage or fill signal blind area where signal is weak or unavailable.
Outdoor:Airports,tourism regions,golf course,tunnels,factories,mining districts,villages,highways...
Indoor:Hotels,exhibition centers,basements,shopping malls,offices,parking lots ...
