Multi-bands Digital Pico Repeaters

HELIOS® Digital Tri-Band Lower Power Pico Repeater is a carrier-grade, consumer-friendly digital smart signal booster that maximizes a subscriber's indoor wireless experience by eliminating in-building dead zones. It is a real cost-effective and intelligent solution to solve the last mile coverage problem, which adopts SDR (Software Define Radio) technology based upon our FPGA & DSP (Digital Signal Processing) Platform. It enables on-the-fly filter change / upgrade by software without expensive hardware upgrading.

The Repeater is connected via coaxial cable to a Donor Antenna and Service Antennas, The Donor Antenna is placed outside the building where it has access to a Macro BTS signal, and the Service Antenna is placed in the building where it can extend radio coverage to the blind areas.

  • Supports Triple band Cellular system 900, 1800 and 2100MHz
