With the development of mobile communication technology, more and more new communication technologies will be adopted nowadays(like 4G). Hence, telecom operators have to face the problem of re-farming spectrum resource for future. 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.
Support Single band system FDD LTE 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.
Built-in AGC & ALC function, "Plug & Play" .
High working gain as min. 70dB.
