Due to the rapid development of the mobile communication industry in the 21st century, the number of mobile communication users is also increasing, so that the cellular planning is getting smaller and smaller, and the base station location is getting lower and lower; on the other hand, with the development of urban construction, high-rise buildings continue to emerge, Based on the shadow effect of wireless transmission, a signal dead zone for mobile communication will be formed behind or in the middle of these high-rise buildings. In addition, during the construction of cellular mobile communication base stations, to avoid interference from adjacent cells, the main lobe of the antenna radiation field pattern has a large down-tilt angle, so that the upper and middle parts of high-rise buildings generally cannot receive signals effectively. In addition, due to the shielding effect of buildings, etc. on electromagnetic waves, it is impossible to receive mobile communication signals normally in some closed large buildings such as tunnels, subways, underground shopping malls, entertainment cities, parking lots, hotels, and office buildings.

The internet signal booster for home is a product specially designed to solve the blind spot of mobile phone signals. Because mobile phone signals rely on the propagation of electromagnetic waves to establish communication links, due to the blockage of buildings, in some tall buildings, basements and other places, some shopping malls, restaurants, karaoke OK, underground civil air defense projects, subway stations and many other places, mobile phone signal Can't reach without using cell phone. The cell phone signal booster for rural areas can solve these problems very well. As long as a cell phone signal booster system is installed in a specific place, the cell phone signal in the entire range can be used well, bringing great benefits to the staff or guests inside. convenience.

The antenna signal booster how to boost cell signal?

1. The principle of mobile phone signal amplifier is very simple. It mainly consists of three parts, antenna, mobile phone amplifier and indoor antenna. These three parts form a wireless system to enhance cellular reception.

2. A cellular reception booster is typically a repeater system that includes amplifiers that add gain or power to reception in all directions. Transmit from an external antenna, receive enhanced power and sensitivity, and then transmit the signal to the cell tower.

3. Downlink: The useful signal that can be called by the outdoor Yagi antenna is input to the host, and after being amplified by the host, it is sent to the indoor ceiling antenna for transmission. In this way, a stable and reliable signal can be received by the user's mobile phone indoors at any time, which is downlink.

4. Uplink: The signal transmitted by the indoor user's mobile phone is absorbed by the ceiling antenna, input to the host, then amplified by the host, and then sent to the outdoor Yagi antenna for transmission to the base station, which is uplink.

The base station (signal tower) is the most important signal source in the process of installing the mobile phone signal amplifier. In the process of installing the equipment, it is better to install the outdoor antenna in the direction of the signal base station.
