Product Description
Helios® Digital Tri Bands Indoor Pico Repeater is an innovation technology, which is adopting SDR (Software Define Radio) technology basis on FPGA & DSP (Digital Signal Processing) platform. It enables on-the-fly filter be changed/upgraded by software without expensive hardware upgrading. It can support multi sub-band selective (bandwidth tunable).
It is connected via coaxial cable to Donor Antenna and Service Antenna, Donor Antenna is placed outside the building where it has easy access to a BTS signal, and the Service Antenna is placed in the building where it can extend radio coverage to the blind area.

  1. Support Tri-band systems .
  2. Support upgrading in case of frequency re-farming by software.
  3. Flexible Bandwidth Adjustable/Upgrade by Software.
  4. Better out of band rejection than analog SAW IF filter.
  5. Support isolation testing between donor antenna and service antenna
  6. Built-in USB interface for local control.
  7. Built-in GPRS modem for remote control.
  8. Compatible with baseband hoping and synthesized hopping.
  9. Built-in AGC & ALC function, "Plug & Play"
  10. High working gain as min. 70dB.
