2g/3g/4g signal booster/repeater 900MHz 1800MHz 2100MHz repeater Tri-band 900 1800 2100 indoor mobile signal booster

Working Principle The principle of GSM900MHz/DCS1800M Wide Band Repeater is the downlink signal received by the Donor Antenna of the base station shall be sent to a band selective filter via duplexer to be filtered and to be amplified by the downlink band selective amplifier to a proper level. The Coverage Antenna via a duplexer shall emit the downlink signal. Similarly, the signal received by the Re-transmission Antenna shall have its level adjusted to a regulated level by a uplink band selective amplifier after it is filtered. The Donor Antenna will emit it after it is filtered and sent to the duplexer Function: Kingtone 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. Main Features 1. High linearity PA; High system gain; 2. Intelligent ALC technology; 3. Full duplex and high isolation from uplink to downlink; 4. Automatic Operation convenient operation; 5. Integrated technique with reliable performance; 6. Bandwidth can be configured from 0.2~25MHz in work band; 7. Local and remote monitoring (optional) with automatic fault alarm &remote control; 8. Weatherproof design for all weather installation;
