The function of this product is to improve the strength of indoor cellphone signals by receiving outdoor cellphone communication signals, transmitting them to the host for amplification, and covering them through indoor antennas, so as to realize a stable and reliable communication experience for all cellphone users indoors.

【Intelligent Chip】:
Using a high-performance core processor and intelligent chip, intelligent adjustment of the internal and external signals, to ensure that in a balanced working condition, effectively reduce signal interference and excessive heating problems, extend the lifespan of the device, and more stable operating gains. 
【Intelligent Digital Display】: Visible high-gain intelligent signal data display, displaying the working status of various parameters at a glance, real-time response to signal stability, convenient for installation and commissioning.
【Wide Coverage】: Accurately enhance the signal, seamless coverage of large households, directional transmission to penetrate thick walls, sweeping the coverage of the blind spots, effectively solving the problem of weak signals.
【Multiple Users】: Faster and more stable signal transmission, supports multiple devices simultaneously, stable and more efficient, to meet the needs of different scenarios. Ultra-strong bandwidth, multi-player smooth use without lag.
【Low Radiation】: Low radiation design, effective shielding of the interference. The use of fine processing material and technology to effectively reduce radiation, and reduce the production of radiation.
【Safety Protections】: Multiple protections design, and automatic interference filtering, to meet the equipment work in the use of safety. Supports signal source protections, short circuit protections, temperature protections, overvoltage protections, and anti-reverse protections.
【Wide Applications】: Easy to install, through the ceiling antenna comprehensive coverage of the use of the place cellphone signal amplifier, does not interfere with the base station, provides a stable and wide cellphone signal coverage, suitable for all major places, and effectively solves the signal problem of weak signal areas. Such as cities, villas, mountains, high-rise offices, dense floors, shopping malls, rural areas, basements, garages, hotels, etc.
