Product Description

 Helios® Digital Dual 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.


Support Dual-band system (GSM/DCS/UMTS/LTE FDD/LTE TDD) is available.
Support upgrading filter parameters in case of frequency re-farming by software.
Flexible Bandwidth Adjustable/Upgrade by Software.
Better out of band rejection than analog SAW filter.
Built-in WEB interface for local control.
Compatible with baseband hoping and synthesized hopping Compatible with baseband hoping and synthesized hopping.
Support maximum 3 sub-bands bandwidth tunable (600kHz-10MHz) both for UL&DL by software.
Built-in AGC & ALC function, "Plug & Play".
High working gain as min. 70dB.


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.
