From its name, we know that the function of the cell phone signal booster is to amplify the signal. The amplifier specially amplifying the mobile phone signal is called the mobile phone signal repeater. The booster is used to amplify the mobile phone signal and is mainly used to solve the problem of the blind spot of the indoor mobile phone signal. Mobile phone signal booster is also called micro repeater, also called mobile phone amplifier.
When choosing a mobile phone signal booster, you need to pay attention to the following issues:
1. Select the model
The mobile phone signal amplifier is mainly selected according to the signal coverage area and the structure of the building. The signal is too weak, the coverage is incomplete, and the signal is too strong, which interferes with the outdoor signal.
2. Arrange the antenna
The directional Yagi antenna is used outdoors, and the direction of the antenna can be pointed to the transmitting base station of the mobile company as much as possible to achieve the best reception effect. The omnidirectional antenna can be used indoors, and the installation height is 2-3 meters. The installation quantity and location of the antenna are related to the indoor area. It is related to the indoor structure. Only one antenna needs to be installed in an indoor unobstructed range of less than 300 square meters, 2 antennas need to be installed in the range of 300-500 square meters, and 3 antennas need to be installed in the range of 500-800 square meters. In addition, the signal sent by the indoor antenna cannot be received by the outdoor antenna during installation, otherwise it will cause self-excitation.
3. The installation of mobile phone signal booster
Generally installed at more than 2 meters above the ground, the distance between the installation location of the equipment and the indoor and outdoor antennas should be routed with the shortest distance (the longer the line, the greater the signal attenuation) to achieve the best use effect. One of the necessary means for the goal of "small capacity and large coverage" is mainly due to the use of repeaters to ensure network coverage without increasing the number of base stations, and secondly, its cost is much lower than that of a microcellular system with the same effect. Repeater is a preferred solution to solve the ability of communication network to extend coverage. 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, In various places such as highways and islands, improve the communication quality, solve the problem of dropped calls, and optimize the wireless communication network.
Mobile phone signal booster classification
There are two types of cell phone signal boosters if they have a display screen. You should also see on the Internet that some mobile phone signal amplifiers have a display screen, and some do not. The mobile phone signal amplifier without a display screen is a relatively common product in the market, an ordinary type; the mobile phone signal amplifier with a display screen is more intelligent, and it was developed later. It has a function of checking the signal received by the antenna. Strong or weak, there is no need to test whether there is a signal on the mobile phone as before, which will be more convenient to install.
In general, mobile phone signal boosters should be small and convenient, with low radiation, small capacity and large coverage.
