Product Description

Helios® Digital Single Band 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.

  • Available customized single band for 2G or 3G or 4G network.
  • Plug-and-play and DSP architecture.
  • Support upgrading in case of frequency re-farming by software.
  • Significantly improve data rates in both weak signal areas and most area with good signal areas.
  • Lower cost of indoor coverage and rapidly increases capacity of wireless networks.
  • Automatic Gain Control (AGC) continuously monitors path loss and transmit power to deliver max gain.
  • SOC & embedded architecture enables to delivery significantly improving network coverage with very low power consumption.
  • Built-in wireless modem for remote monitoring by SMS, GPRS or TCP/IP.
  • Support upgrading firmware remotely by GPRS.


To expand signal coverage of fill signal blind area where celluar signal is weak or unavailable.
Indoor: Hotels, Exhibition Centers, Basements, Shopping Malls, Offices, Parking lots, etc.
