Product Description

1900MHz GSM Cell Phone Signal Booster 70dB Gain Repeater Extender

Product Overview

The 1900MHz GSM Cell Phone Signal Booster with 70dB Gain is a professional-grade repeater extender designed to solve indoor signal coverage problems caused by architectural obstacles and signal attenuation. This cellular signal repeater amplifier provides an affordable, high-performance solution for weak signal zones.

How It Works

The repeater functions as a relay between the base station (BTS) and mobile devices. It captures the strongest available signal via the donor antenna, linearly amplifies it, and retransmits the enhanced signal through the indoor distribution system to areas with weak or no coverage. The system operates bidirectionally, also amplifying mobile signals back to the base station.
