br / Helios GSM900MHz / GSM1800MHz RF Repeater system is designed to solve problems of weak mobile signal, which is much cheaper than adding a new Base Station (BTS). Main operation of GSM RF Repeater system is to receive low-power signal from BTS via radio frequency (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.
br / According to your requirement for working frequency, you can choose either type of Helios GSM900MHz / GSM1800MHz RF Repeater:
br / 1. GSM Band Selective RF Repeater System: to amplify all signals in the whole band (Bandwidth is customized)
br / 2. GSM Wireless Channelized RF Repeater System: to amplify only the signals transmitted by the customized nbsp;2 or 4 or 6 channel (A narrow band with customized central frequency)
br / Features:
br / 1. Comply with relevant regulation spectrum usage
br / 2. Aluminum-alloy casing with IP65 protection and compact design, cool system without fan
br / 3. ALC and AGC to ensure stable operation
br / 4. Easy to install on wall or pole
br / 5. Highly selective channel selector can process 1 or 2 or 4 or 6 or 8 channels simultaneously
br / 6. Adopting filter with highly selectivity and low insertion loss eliminates interference between uplink and downlink
br / 7. 2 RS-232 ports provide links to laptop for local test or to built-in wireless modem for communication with the NMS
br / 8. High gain linear power amplifier technique with reliable performance
