What is a signal amplifier? What is the function?

The signal amplifier is a micro repeater, also called cell phone signal amplifier, also called cell phone companion. From its name, we know that the function of signal amplifier is to amplify signals. There are many kinds of signal amplifiers, such as TV signal amplifiers and radio amplifiers. All receivers have signal amplifiers. The amplifier specialized in amplifying mobile phone signals is called mobile phone signal amplifier, which is mainly used to solve the problem of indoor mobile phone signal blind area.

Using repeater as one of the necessary means to achieve the goal of "small capacity and large coverage" is mainly because it ensures network coverage without increasing the number of base stations, and its cost is much lower than that of microcellular systems with the same effect. Repeater is the best solution to solve the problem of extended coverage of communication network. Compared with the base station, it has the advantages of simple structure, less investment and convenient installation. It can be widely used in shopping malls, hotels, airports, docks, stations, gymnasiums, entertainment halls, subways, tunnels, expressway, islands and other blind areas and weak areas that are difficult to cover, improving communication quality, solving the problem of dropped calls and optimizing wireless communication networks.
