Description
With the development of mobile communication technology, more and more new communication technologies (like 3G&4G) will be adopted nowadays. Hence, telecom operators have to face the problem of re-farming spectrum resource for future. Helios® Digital Tri Bands 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.
