Mobile phone signal amplifier is also called micro repeater, also called mobile phone companion. We know from its name that the function of the signal intensifier is to amplify the signal. The amplifier specially amplifying the signal of mobile phone is called the signal intensifier of mobile phone. The amplifier is used to amplify the signal of mobile phone. It is mainly used to solve the problem of blind area of indoor mobile phone signal. The following problems should be paid attention to when installing and using the signal amplifier of mobile phone:


First choice model. Mobile phone signal amplifier is mainly selected according to signal coverage area and structure of buildings. The signal is too weak, the coverage is not complete, the signal is too strong, and it interferes with the outdoor signal.


The second arrangement is antenna. Outdoor use of directional Yagi antenna, antenna direction can point to the mobile company's base station as far as possible, in order to achieve the best reception effect, indoor use of omnidirectional antenna, installation height of 2-3 meters, the number and location of antenna installation is related to indoor area and indoor structure, an indoor unobstructed range of 300 square meters or less only One antenna needs to be installed. Two antennas need to be installed in the range of 300-500 square meters and three antennas need to be installed in the range of 500-800 square meters. In addition, the signals emitted by the indoor antenna during installation can not be received by the outdoor antenna, otherwise self-excitation will occur.


Outdoor Antenna of Mobile Phone Signal Amplifier


Installation of the third cell phone signal intensifier. Generally installed above 2 meters from the ground, the location of equipment installation and the distance between indoor and outdoor antennas should adopt the shortest route (the longer the line, the greater the signal attenuation) in order to achieve the best use effect, using repeater as one of the necessary means to achieve the goal of "small capacity, large coverage", mainly due to the use of repeater 1. On the premise of not increasing the number of base stations, network coverage is guaranteed. Second, the cost of the system is much lower than that of the microcellular system with the same effect.


Repeater is an optimum scheme to solve the extended coverage capability of 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 areas and weak areas which are difficult to cover, such as shopping malls, hotels, airports, wharfs, stations, gymnasiums, entertainment halls, subway, tunnels, highways, islands and other places. It can improve the quality of communication and solve the problem of dropped calls. Chemical wireless communication network.


Classification of Cell Phone Signal Amplifiers


There are two types of cell phone signal enhancers if they are classified as having a display screen. On the Internet, we should also see that some of the cell phone signal amplifiers have a display screen, while others do not. Mobile signal amplifier without display screen belongs to a common product in the market, ordinary type; mobile signal amplifier with display screen is more intelligent, which was developed later. It has a function of checking the strength of the received signal of antenna, so it does not need to test whether there is a mobile phone like before. There is a signal, so it will be more convenient to install.


Generally speaking, cell phone signal intensifier should be small and convenient, low radiation, small capacity and large coverage.
