Digital Dual Band Home Repeater

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 optimize their network and offer best service to users to improve their competitive ability. However, 3G or 4G signals attenuate severely when traveling through walls, floors, and windows, leaving more than 40% of all indoor spaces with inadequate coverage and poor data throughput. Then the operators need a cost-effective solution to resolve such coverage problems easily and rapidly.

Helios® SignalTouch Series Digital Dual Band ICS Home 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 really 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 to be changed/upgraded by software without expensive hardware upgrading.

Fully wireless design, built-in Donor Antenna and Service Antenna achieve true “Plug & Play” – basically no need for configuration and free of maintenance. 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.
