How It Works
The repeater acts as a relay between the base station and mobile devices:
- Outdoor antenna receives signal from nearest mobile base station
- Signal travels through coaxial cable to the repeater
- Amplified signal transmits through indoor antenna system
- Mobile devices receive improved signal quality for calls and data
Key Features
- Dual-band operation at 850MHz and 2100MHz frequencies
- 70dB high gain amplification for significant signal improvement
- ALC/AGC function prevents base station interference
- Supports CDMA 2G/3G and WCDMA 3G/4G networks
- Easy installation with comprehensive user manual
- Reduces mobile phone radiation by improving signal strength
