High-Power Indoor Product Technical Solution

Solution Overview

This solution is based on a three-tier network architecture (receiver unit → processing unit → high-power transmitter unit), using optical-electrical composite cables (≤500 meters) and optical fiber (≤10km) to cascade the transmission signal, supporting multi-band 2G/3G/4G/5G and NB-IoT IoT extension. The system can be expanded to seven transmitter units, with each unit independently powered, suitable for high-difficulty coverage scenarios like old residential areas.

Architecture Description

• Receiver and data units use optical-electrical composite cables, length ≤ 500m
• High-power transmitter units are independently powered, with the system linked by optical fiber, length ≤ 10km
• Up to seven high-power transmitter units can be connected

Application Case

Old Residential Area Signal Coverage Case Introduction: A project in a residential area in Deyang, Sichuan Province, for a 12-building, 4-story walk-up complex (including 25 double-unit buildings, 22-24/27-31 triple-unit buildings, and 21/32 four-unit buildings). We used a wireless digital shared high-power equipment solution, deploying 1 DOS receiver unit, 1 DTS processing unit, 5 transmitter units (1.8G+2.1G frequency bands), and 15 custom antennas. After implementation, the signal in the corridors and stairwells of the residential area remained stable at -88dBm, SINR reached 8dB, voice calls and internet speed were normal, and user experience was positive.
