RF Repeaters system is designed to solve problems of weak mobile signal,which is much cheaper than adding a new Base Station (BTS).
Outdoor TETRA RF Channel Selective Repeaters to amplify only the signals transmitted by the customized 1 or 2 or 4 or 6 or 8 channel. It depends on customized frequency.
Application:
To expand signal coverage of signal blind areas where signal is weak or unavailable.
Outdoor: Airports, Tourism Regions, Golf Courses, Tunnels, Factories, Mining Districts, Villages etc.
Indoor: Hotels, Exhibition Centers, Basements, Shopping Malls, Offices, Packing Lots etc.
