5G can indeed bring faster network speeds and a smoother experience, but it is also necessary to see that 5G mobile phone signals also have its drawbacks. 5G signals are faster, but it also means higher requirements for signal base stations. A few days ago, Nokia said that 4G base stations can be upgraded to 5G base stations through software. In fact, it takes about 200-300 meters to cover a 5G base station in the central area of the city, about 500 meters to 1 km in the suburbs, and a 5G base station in the countryside from 1.5 to 2.5 kilometers. This puts a lot of pressure on operators and tower companies in infrastructure construction, and requires huge investment in economy, manpower, and time. So it is not a short-term that 5G signals can be fully rolled out like the previous 3G and 4G signals.
The call between the mobile phone and the mobile phone is forwarded through the base station. The mobile phone’s ability to make and receive calls mainly depends on the support of the communication base station. After the mobile phone is turned on, it will actively connect to the communication base station closest to him, and the communication base station will command it when making and receiving calls. In fact, it is all communication with the communication base station. So if the prison wants to interrupt the communication between prisoners and the outside world, what needs to be done? The noise generated by the mobile cell phone jammer covers the signal jammer of the mobile phone. The noise is so great that the base station cannot hear the mobile phone. The answer is very simple. It only needs a machine with the same frequency as the mobile phone to make noise, so when the base station tries to connect to the mobile phone when. You will find that the signal coming from the mobile phone is messy and unrecognizable, so you will refuse to communicate with the mobile phone.
