Why is your cell phone signal so bad?

With the development of the information age, the needs of life and consumption such as games, videos, online shopping, takeaway, and express delivery are inseparable from mobile phones. Sometimes the mobile Internet signal is good and bad, and the web page information cannot be swiped out, and watching videos and playing games freezes. So what is the reason why the mobile phone signal is so weak? What does the strength of the mobile phone signal depend on?

In the process of receiving and sending signals, the mobile phone needs to use a special baseband chip to encode and decode the signal. Generally speaking, the baseband chip is a “translation”. If the “translation” is not efficient, it will cause the mobile phone signal to be weak.

When we are farther away from the base station, the signal receiving distance increases, and the signal of the mobile phone becomes weaker. If the mobile phone wants to receive high-quality signals, it must increase the power. In the same way, if you want the base station to “receive the signal”, you need to increase the power of the sent signal, which will also cause the phone to freeze and affect the use effect.

Electromagnetic waves propagate along the direction controlled by the antenna, and when encountering obstacles that hinder the propagation of electromagnetic waves, such as metal casings of cars and trains, glass of buildings and other penetrable obstacles, the mobile phone signal will attenuate. If it is in a basement or in an elevator, the area is small or on the edge of an obstacle, the electromagnetic wave of the obstacle at this time is difficult to penetrate or diffract, and the mobile phone may have no signal at all.


The network we use every day is called Cellular Mobile Communication, which uses cellular wireless networking to divide a large area into many small areas, and set up a base station in each small area. Each base station is responsible for the contact and control of user terminals in the area, so that users can communicate with each other during activities, and has the functions of handover and automatic roaming across local networks. The coverage of each area is mainly determined by the azimuth and downtilt angle of the antenna.


It can be seen that the strength of mobile phone signals is closely related to the terrain environment, network coverage requirements, baseband chips, base station transmission power, propagation obstacles, antenna installation methods and other actual conditions. Different networks and base stations in different cells have different wireless frequencies, and their wireless transmission characteristics are also different.

In life, when we encounter a situation where the mobile phone has no signal, it may be that the service range of the base station is limited, and the signal will gradually weaken as the distance increases. And if you happen to be in the blind area served by the base station, the signal will be relatively weak.At this time, we need a repeater with full signals to easily solve various signal problems! If there is such a demand, please feel free to contact us!
