What is a cell phone signal booster?

Admin Posted on 2020-11-30

Cell phone signal booster is also called mini repeater, also called cell phone companion. From its name, the signal booster knows that its function is to amplify the signal. Amplifiers that specialize in amplifying cell phone signals are called cell phone signal boosters. Boosters are used to amplify cell phone signals and are mainly used to solve the problem of indoor cell phone signal blind spots. The installation and use of mobile phone signal amplifiers should pay attention to the following issues:

First choice model. Cell phone signal amplifiers are mainly selected according to the signal coverage area and the structure of the building. The signal is too weak, the coverage is not complete, the signal is too strong, and there is a signal jammer to the outdoors.

The second arrangement of the antenna. The directional Yagi antenna is used outdoors, and the direction of the antenna can be as far as possible to point to the mobile company’s transmitting base station to achieve the best reception effect. The omnidirectional antenna can be used indoors. The installation height is 2-3 meters. The number and location of the antenna installation and the indoor area Depending on the indoor structure, only one antenna is required for an indoor unobstructed area below 300 square meters, two antennas are required for a range of 300-500 square meters, and three antennas are required for a range of 500-800 square meters. In addition, the signal emitted by the indoor antenna during installation cannot be received by the outdoor antenna, otherwise self-excitation will occur.

Installation of the third cell phone signal booster. Generally installed at a distance of more than 2 meters from the ground, the installation location of the equipment and the distance between the indoor and outdoor antennas should use the shortest wiring method (the longer the line, the greater the signal attenuation) in order to achieve the best use effect. Use a repeater as a realization. One of the necessary means for the goal of "small capacity and large coverage" is mainly due to the use of repeaters, one is to ensure network coverage without increasing the number of base stations, and the other is that its cost is much lower than that of a microcellular system with the same effect. The repeater is a preferred solution to solve the extended coverage capability of the communication network. Compared with base stations, it has the advantages of simple structure, less investment and convenient installation. It can be widely used in blind and weak areas that are difficult to cover, such as shopping malls, hotels, airports, docks, stations, stadiums, entertainment halls, subways, tunnels, Highway, island

In various places, improve communication quality, solve the problem of dropped calls, and optimize the wireless communication network.
