4-Band Cell Phone Signal Booster | 800-900-1800-2100 MHz Full-Band Enhancement with LCD Display for Basements, Rural Areas, and Large Buildings – Bochuang Shikong
Bochuang Space-Time's quad-band mobile signal booster precisely covers four frequency bands: 800MHz, 900MHz, 1800MHz, and 2100MHz. It fully supports 2G/3G/4G networks, effectively eliminating signal dead zones in basements, mountainous areas, large factories, hotels, and more. The main unit features a high-definition LCD screen that displays real-time signal strength and operating status for each band, making monitoring and troubleshooting easy. The kit includes a high-gain outdoor log-periodic antenna, an indoor omnidirectional mushroom-head antenna, 20 meters of low-loss feeder cable, and a stable power adapter. Installation is simple and requires no professional tools. The device uses intelligent AGC (Automatic Gain Control) technology to prevent signal overload and interference with base stations, ensuring reliable operation. Its metal housing features heat-dissipating design, supporting 7×24 hours of continuous operation. Ideal for homes, offices, warehouses, shopping malls, and other environments, it significantly improves call clarity and internet speed.

Frequently Asked Questions (FAQ)
This modelAmplifierCan it boost signals from multiple carriers at once?
Yes, it supports quad-band 800/900/1800/2100MHz to simultaneously enhance 2G/3G/4G signals from major carriers like China Mobile, China Unicom, and China Telecom, achieving "triple-network integration."
"Covered."
Is installation complex? Do I need a professional?
Installation is simple and requires no technical expertise. Just mount the outdoor antenna in a location with strong signal (e.g., on the roof), then connect it using 20 meters of cable.feederConnect to the host, then move indoors
Place the antenna in the area you want to cover. We provide a detailed installation guide.
What is the purpose of an LCD display?
The LCD screen displays real-time signal strength and status for each band, helping you quickly verify device operation and identify weak bands for easier debugging.
Optimize installation location.
Will this device interfere with the base station?
No. The device features built-in intelligent AGC (Automatic Gain Control) that automatically reduces output power when signal strength is too high, preventing interference with the base station and ensuring compliance.
Safe operation.
What are the use cases?
Ideal for areas with weak or no signal, such as basements, mountainous regions, large factories, hotels, shopping malls, offices, and warehouses. Especially suitable for scenarios requiring coverage across multiple operational zones.
Complex environment of commercial networks.
