Dual Band Signal Repeater 900 1800mhz Multi Band Signal Booster
dual band signal repeater 900 1800mhz multi band signal booster
Telecommunication Equipment Wireless Networking Equipment
Description:
Kingtone GSM Repeaters system is designed to solve problems of weak mobile signal, which is much cheaper than adding a new Base Station (BTS). Main operation of RF Repeaters system is to receive low-power signal from BTS via radio frequency transmission and then transmit the amplified signal to the areas where network coverage is inadequate. And the mobile signal is also amplified and transmitted to the BTS via the opposite direction.
Features:
High linearity PA; High system gain;
Intelligent ALC technology;
Full duplex and high isolation from uplink to downlink;
Automatic Operation convenient operation;
Integrated technique with reliable performance;
Local and remote monitoring (optional) with automatic fault alarm &remote control;
Weatherproof design for all-weather installation;
Application:
Outdoor: Airports, Tourism Regions, Golf Courses, Tunnels, Factories, Mining Districts, Villages etc.
Indoor: Hotels, Exhibition Centers, Basements, Shopping Malls, Offices, Packing Lots etc.
