Product Description

Helios® SignalTouch Series Single Band Digital 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 real cost-effective and intelligent solution to solve the last mile coverage problem, 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 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. In fact, SignalTouch will be able to intelligently and automatically senses and adapts to its dynamic RF environment. By continuously monitoring the gain and making real-time adjustments, the system will never overdrive the base station or raise the noise floor. SOC & Embedded architecture enables to delivery significantly improving network coverage with very low power consumption.

  • Support Tri-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.
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
