With the development of science and technology, the positioning, tracking and monitoring of mobile phones have become the most important reconnaissance methods and sources of intelligence in countries around the world. As long as the mobile phone is carried in secret-related places, whether it is used or turned on, it is extremely likely to cause leakage of secrets and cause serious harm to units or individuals, even the party and the state. Only through technical means can cell phone signals be shielded in a small area within the venue area.
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 jammer.Boosters are used to amplify cell phone signals and are mainly used to solve the problem of indoor cell phone signal blind spots.
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…
