Helios® GSM900MHz RF 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 (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.

According to your requirement for working frequency, you can choose either type of Helios® UGSM900MHz RF Repeaters:

1. Band Selective RF Repeaters System: to amplify all signals in the whole band (Bandwidth is customized)
2. Wireless Channelized RF Repeaters System: to amplify only the signals transmitted by the customized  1 or 2 or 4 or 6 or 8 channel (A narrow band with customized central frequency)


Features:

1. Comply with relevant regulation spectrum usage;
2. Aluminum-alloy casing with IP65 protection and compact design, cool system without fan;
3. In-built ALC firmware for maximal linear output power;
4. Unique max AGC60dB firmware to ensure stable operating on moving platforms such as ship or trains;
5. Easy to install on wall or pole;
6. Highly selective channel selector can process 1 or 2 or 4 or 6 or 8 channels simultaneously;
7. Adopting filter with highly selectivity and low insertion loss eliminates interference between uplink and downlink;
8. Exact traffic statistics & analysis through baseband analysis;
9. 2 RS-232 ports provide links to laptop for local test or to built-in wireless modem for remote control & monitoring through SMS or GPRS/Datalink + TCP/IP;
10. High gain linear power amplifier technique with reliable performance.
11. Built-in NMS firmware & Software support interfaces / protocols of SNMP, CORBA, ASCII etc and easy to be integrated into operator's current 3rd party

telecom NMS system, or integrated 3rd party telecom equipment into Helios NMS system which support SNMP interface.
