With the rapid development of mobile communication network, people have become more and more convenient way of life. This convenient way of life makes people rely more and more on smartphones and the Internet, but there are often places that cannot be covered by the Internet. However, because electromagnetic waves propagate in a straight line, they are usually interfered in the following places, for example: in some tall buildings, basements, shopping malls, restaurants, home rooms, entertainment places and many other places, there are still some weak links in wireless communication that cannot satisfy customers The mobile phone signal is so weak that the mobile phone cannot be used normally. At present, there are mainly the following problems:
1) Blind area: the signal blind area caused by the area being too far away from the base station and not within the radiation range of the base station;
2) Weak area: The main reason is that the signal is lower than the receiving sensitivity of the mobile phone after loss, resulting in poor mobile phone calls;
3) Conflict zone: mainly in high-rise building areas, the wireless signals come from multiple cells, and most of them are unstable reflection signals from the ground and walls, resulting in frequent switching (ie ping-pong effect), which seriously affects the normal communication of mobile phones;
4) Busy area: It is mainly an area with large traffic volume. The number of users in this area exceeds the load of the base station at the same time period, and users cannot access the mobile network for normal communication.
The cell signal booster is a product specially designed to solve the above weak areas of mobile phone signals. Such products have the characteristics of small size and flexible installation, and can provide deep coverage of indoor signals. Practice has proved that they can provide stable and reliable signals for indoor mobile communication users, enabling users to enjoy high-quality personal communication services indoors.
