Long Distance Cellular Booster Lte Band 28 Amplificador 700mhz 4G Lte Signal Booster Repeater B28 Cell Amplifier is designed to solve problems of wak mobile signal, which is much cheaper than adding a new base station (BTS).Main operation of the repeaters are to receive lower-power signal from BTS via RF 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:
1,Output Power +30dBm – +43dBm for large coverage application;
2,High working gain as Min. 95dB;
3,Adopting filter with highly selectivity and low insertion loss eliminates interference between uplink and downlink;
4,RS232 ports provide links to laptop for local setting and monitoring by built-in web interface;
5,Built-in wireless modem (Option) for remote monitoring by SMS or GPRS;
6,Details repeater parameters and status can be monitoring by Control Panel, such as temperature, output power level, gain, ATT, return loss, VSWR etc;
7,Support upgrading firmware remotely by GPRS;
8,High gain linear power amplifier technique with reliable performance;
9,Compact size and light weight, easy to install on wall or pole;
