Description

HELIOS® Digital Single 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 adopts SDR (Software Define Radio) technology based upon our FPGA & DSP (Digital Signal Processing) Platform. It enables on-the-fly filter change upgrade by software without expensive hardware upgrading.
Intelligent Interference Cancellation
HELIOS® Digital Off-Air Repeaters include a Panted ICS (Interference Cancellation System) Feature. It measures the Isolation between Donor and Service Antennas and intelligent cancel the interference in real time. With ICS function, it prevents self-oscillation, enhance gain and coverage range and reduce isolation requirement between Donor Antenna and Services Antenna.
Intelligent Solution for UL Interference
HELIOS® Digital Repeaters detect Uplink activity and support muting. This means that when there is no activity in the Uplink, the Uplink is automatically closed in FPGA to prevent Uplink transmission from the Repeater to the BTS. When a call (voice or data) is made, the UL Squelch Algorithm activates the Repeater Uplink Channel. Automatic UL Gain adjustment according to the Downlink gain will also minimum the UL interference to the BTS.
The Repeater 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.
