Description:

Helios® 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® RF Repeaters:

Band Selective RF Repeaters System: to amplify all signals in the whole band ( Various bandwidth is available upon request)
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:

Aluminum-alloy casing with IP65 protection and compact design, cool system without fan
In-built AGC & ALC function be able to ensure easy installation without setting
Unique max AGC60dB firmware to ensure stable operating on moving platforms such as ship or trains
Compact size and light weight, easy to install on wall or pole
High working gain as Min. 90dB
Output power + 30dBm - + 43dBm for large coverage application
Adopting filter with highly selectivity and low insertion loss eliminates interference between uplink and downlink
2 RS232 or RJ45 ports provide links to laptop for local setting and monitoring by built-in web interface.
Built-in wireless modem ( Option) for remote monitoring by SMS, GPRS or TCP/ IP.
Details repeater parameters and status can be monitoring by built-in web interface, such as RSSI, temperature, output power level, gain, ATT, return loss, VSWR etc.
Support upgrading firmware remotely by GPRS.
High gain linear power amplifier technique with reliable performance

Applications:

To expand signal coverage of fill signal blind area where signal is weak or unavailable.

Outdoor: Airports, Tourism Regions, Golf Courses, Tunnels, Factories, Mining Districts, Villages etc.
Indoor: Hotels, Exhibition Centers, Basements, Shopping Malls, Offices, Packing Lots etc

The RFR is mainly applicable to such case:

The repeater can find an installation place which can receive pure BTS signal at strong enough level as the Rx Level in repeater site should be more than -70dBm;
And can meet the requirement of antenna isolation to avoid self-oscillation.
