cell phone signal amplifier are mainly needed for the following four points:
1. China with the rapid development of the mobile business, mobile communications users have increased, so that the cellular cellular planning is getting smaller and smaller, the base station location is getting lower and lower, the signal coverage is getting smaller and smaller;
2. With the development of urban construction, high-rise buildings continue to emerge, based on the shadow effect of wireless propagation, behind these high-rise buildings or the middle layer will form a mobile communication signal blind spot;
3. cellular mobile signal base station in the construction process, because to avoid interference from neighboring cells, its antenna radiation direction map main flap has a large downward angle, so that the upper part of the high-rise building in general can not effectively receive signals;
4. Due to the shielding effect of buildings on electromagnetic waves,
Cell phone signal amplifier is to solve the above four major problems and produce, as long as in a specific place to install a set of cell phone signal amplifier equipment, the whole range of cell phone signal can be very good to use, to the staff or guests inside to bring a great deal of convenience, cell phone signal amplifier can be an effective solution to the problem of poor signal of the tall buildings, office buildings, basements, restaurants, villas, elevators and many other places.
