Model Number: BT-4AXXA Brand Name: BOOSTEL Key Specifications/Special Features: Dual-band RF repeater (RFR) is designed to provide a more cost-effective solution than adding a new Base Transceiver Station (BTS) to improve signal coverage and communication quality in dual band system. And its easy installation and maintenance can help carrier get fast returnThe repeater is working as a relay between the BTS and mobiles. It receives the low-power signal from BTS via the Donor Antenna, linearly amplifies the signal and then retransmits it via the Coverage Antenna to the weak/blind coverage area. And the mobile signal is also amplified and retransmitted to the BTS via the opposite directionAs per operator’s requirement for working frequency, two types of RFR are available:Band-selective RF repeater: to amplify all signals in the whole band (bandwidth is customized)Channel-selective RF repeater: to amplify only the signals transmitted by the customized channels
