HELIOS® CardMux™ Multi-Band Multi-Operator Digital Off-Air Repeater

Universal Multi-Band, Multi-Service, Software-Based Repeater Platform

With the development of mobile communication technology, more and more new communication technologies (like 4G) will be adopted nowadays. Hence, telecom operators have to handle multi system simultaneity and have to face the problem of re-farming spectrum resource for future. For Traditional Multi Band RF Repeaters, most of the manufacturers adopt all-in-one architecture with huge size. Furthermore, it’s impossible to be very easily upgraded in case of frequency re-farming or add new technique in the near future, which will waste operator’s old investments.

For the reasons mentioned above, Helios develops and brings out Helios® CardMux™ Series Digital Multi Band Repeaters to resolve such problem. It provides software-based platform and enables on-the-fly filter to be changed/upgraded by software without expensive hardware upgrading. It supports both multi sub-bands selective and/or channel selective function. It supports upgrading from Single Band to Dual Band/Tri Band/Quad Band and even eight Bands with adding separate RF Cards easily.

Helios® CardMux™ Digital Multi-Band 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 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.

Key Features
