Repeater is to achieve "small capacity, large coverage" and the design of the product, is to solve the extension of communication network coverage of the preferred program. The use of repeater is to extend the coverage of the network without increasing the number of base stations, and its cost is much lower than the microcell system with the same effect. It is easy to cover the blind and weak areas, such as shopping malls, hotels, restaurants, karaoke OK, sauna, airport, terminal, station, gymnasium, gymnasium, Entertainment, subway, tunnels, highways, islands and other places, improve the quality of communications, to solve dropped calls and other issues.
