Tri-Band Cellular Signal Booster for Home & Office

Product Introduction

1. Comprehensive Tri-Band Enhancement: Precisely covers the three core mobile communication frequency bands of 900MHz, 1800MHz, and 2100MHz, effectively enhancing voice and data signals of mainstream 2G, 3G, and 4G networks in China and most regions, providing a one-stop solution for multi-standard network coverage.

2. Superior Gain and Wide Coverage: Provides a system gain of up to 65-75dBi, significantly improving signal strength and quality. Designed to cover an area of over 300 square meters, sufficient to meet the comprehensive coverage needs of typical homes, multi-story villas, or small office areas.

3. Multi-Antenna Driving Capability: The main unit can drive 4 to 10 indoor antennas, allowing users to flexibly deploy multiple ceiling-mounted or wall-mounted antennas according to room layout and signal blind spots, achieving a uniform signal distribution without dead zones, especially suitable for complex apartment layouts.

4. Stable Performance and Safety Design: Output power is controlled within a reasonable range of 22±3dBm, providing effective signal amplification while avoiding interference with outdoor base stations. The product is designed to comply with regulations, ensuring stable and reliable operation.

5. Streamlined Design, Relatively Simple Installation: The device integrates signal amplification and distribution functions. A clear installation guide is provided; users can complete the basic installation themselves by correctly positioning the outdoor receiving antenna, indoor transmitting antenna, and connecting the main unit, thus improving the indoor communication experience.

Application Scenarios

FAQ

Q: Does installing this signal booster require professional assistance?

A: Users with basic hands-on skills can install it themselves according to the instructions. However, to ensure optimal performance and compliance (especially regarding the location of the outdoor antenna), it is recommended that the first installation be guided by a professional or someone familiar with RF products.

Q: Does it support 5G signals?

A: No. The GLS3GDW-BH-2 is a 3G/4G signal booster designed for the 900/1800/2100MHz frequency bands. For 5G signal enhancement, please select a model that supports the corresponding 5G frequency band (e.g., 3.5GHz).

Q: Does using a signal booster have any health effects?

A: A properly installed signal booster simply receives and amplifies existing weak outdoor signals. Its indoor transmission power is far lower than the power directly transmitted by a mobile phone and is within safety standards. As long as it is installed correctly, it will not increase any additional health risks.

Q: Where should the outdoor antenna be installed?

A: It should be installed in a location where it can reliably receive one to two bars of outdoor signal. Generally, the higher and more towards the base station, the better. At the same time, ensure that the outdoor antenna and indoor antenna are kept as far apart as possible (at least 10-15 meters vertically or horizontally is recommended), and use a wall to separate them to prevent system self-oscillation.
