Product Description
Product Overview
The 850MHz/1800MHz Dual Band Signal Booster provides an affordable solution to solve indoor signal coverage problems caused by signal fading and architectural obstacles. This 2G/3G/4G network repeater features easy installation and maintenance for fast deployment and return on investment.
How the Signal Booster Works
The repeater functions as a relay between the base station and mobile devices, amplifying weak signals to provide reliable communication in areas with poor coverage.
Operation Process
- The outdoor antenna receives signals from the nearest mobile base station
- Signals are transmitted via coaxial cable to the repeater unit
- The repeater amplifies the weak signals with ≥70dB gain
- Enhanced signals are distributed through indoor antennas
- Mobile devices receive improved signal quality for reliable communication
