Product Description
The Helios® Digital Band & Channel Selective Repeater is a new kind of RF Repeater that is adopting DSP (Digital Signal Processing) technology basis on FPGA platform, highly linear components and unparalleled innovative DSP filtering provide top level performance. The Helios Digital Band & Channel Selective Repeater can be selected as Band Selective or Channel Selective operation mode, which supports up to 12 channels both on uplink and downlink. Using an advanced ALC mechanism, each one of the channels has an individual gain and ALC setting.

The Band Selective Booster Series provides band selective functions to satisfy the demanding customers (Various bandwidths are also available). The band selective function, together with the strong out-of-band gain, totally avoids improving the competitors' signal coverage. And also is with Automatic Gain Control (AGC) to avoid the Booster from over saturation, therefore maintaining a high voice quality and avoid adding interference to network. With good looking & super compact design also make it attractive. Besides, its easy installation feature is also for individual customers to install the booster by themselves, and it does not need much professional knowledge and instrument.

Features
 
  • Support Multi-band systems .
  • Support upgrading in case of frequency re-farming by software.
  • Flexible Bandwidth Adjustable/Upgrade by Software.
  • Better out of band rejection than analog SAW IF filter.
  • Support isolation testing between donor antenna and service antenna
  • Built-in USB interface for local control.
  • Built-in GPRS modem for remote control.
  • Compatible with baseband hoping and synthesized hopping.
  • Built-in AGC & ALC function, "Plug & Play"
  • High working gain as min. 70dB.
  •  
Applications
 
To expand signal coverage of fill signal blind area where cellular signal is weak or unavailable.
  • Indoor: Hotels, Exhibition Centers, Basements, Shopping Malls, Offices, Parking lots, etc.
