We can often see that in tall buildings, basements, shopping malls, restaurants, karaoke sauna massage and other entertainment places, underground civil air defense projects, subway stations and many other places have installed mobile phone signal amplifiers to solve the problem of signal difference in these blind and weak areas Why is mobile signal amplifier widely used by users? There are five main reasons.


1. With the rapid development of China's mobile communication industry, the number of mobile communication users is increasing. As a result, the cellular planning is getting smaller and smaller, the location of the base station is getting lower and lower, and the signal coverage is getting smaller and smaller.


2. With the development of urban construction, high-rise buildings are emerging. Based on the shadow effect of wireless transmission, the signal blind area of mobile communication will be formed behind or in the middle layer of these high-rise buildings.


3. In the construction process of cellular mobile communication base station, the main lobe of antenna radiation field pattern has a large downward angle, so that the signal cannot be received effectively in the middle and upper part of high-rise buildings.


1. Due to the shielding effect of buildings on electromagnetic wave, some closed large amplifier systems, such as tunnels, subways, underground shopping malls, entertainment cities, parking lots, hotels and office buildings, can be used well in the whole range of mobile phone signals, bringing great convenience to the staff or guests.


2. In some remote areas, the base station construction is not in place, and users need the operator to add the base station, but this signal coverage project is recommended to have a long period and a large cost, so most users prefer to install a mobile signal amplifier for signal coverage.


The above content is the reason why users tend to use the mobile signal amplifier to improve the signal difference.
