Overview

Statistics show 70% of 4G mobile services takes place indoors. Considering the diversified 5G mobile services and expanded mobile industry boundary, this figure will increase to 85%. Therefore, the quality indoor network will be the core competitive edge of mobile operators in 5G era. When the network evolves from 4G to 5G, it will face multiple challenges in indoor mobile network, such as user experience, capacity expansion, network coverage and so on. 5G mobile network use C-band and mmWave that are on much higher frequency bands than 2G, 3G, and 4G counterparts. Higher frequency bands lead to greater link losses. The signals on the higher mmWave band even will experience difficulty in penetrating through a wall as the link loss exceeds 60dB.

HELIOS® Next-Generation Multi-Band 4G LTE & 5G-NR Digital Off-Air 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. With ultra-low-noise RF frontend, innovative digital filter, high SFDR (Spurious Free Dynamic Range) ADC, 5G NR based-band synchronization algorithms in SDR, Helios® Next-Generation Multi-Band 4G LTE & 5G NR Digital Off-Air Pico Repeater enables adaptive, accurate, speedy and reliable frame synchronization with 5G NR gNB and working in harmony with macro network. HELIOS® Next-Generation Multi-Band 4G LTE & 5G NR Digital Repeater is designed for FDD & TDD Telecom Operators who are looking to enhance 4G & 5G coverage where cellular signal is weak or unavailable or poor data throughput in small-size coverage scenario. It is a fast, simple and intelligent solution to solve the last mile coverage problem. It will be connected via coaxial cable to an outside 2T2R Donor Antenna and several 2T2R Indoor Services Antennas, Donor Antenna is placed outside the building where it has easy access to 4G LTE and 5G NR gNB signal, and the Service Antennas are placed in the building where they can extend 4G & 5G NR radio coverage to the blind area.
