Why do mobile phones intercept many pseudo base stations?

First of all, "pseudo base stations" generally transmit powerful power signals through the power amplifier transmitting antenna, and the frequency band is the same as that of operators.

It will block the signal of the original operator, and then criminals will use the defects of the mobile network location registration process to trick mobile phone users into receiving strong signals from "pseudo base stations"

And access, so as to realize signal interception and implement illegal acts.

A "pseudo base station" generally consists of a host computer, a notebook computer and an antenna. Then, through the SMS sender and other related equipment, search for the information of mobile phone cards within a certain radius around it, and forcibly send all kinds of short messages to mobile phone users within this range by pretending to be a base station of an operator or using someone else's mobile phone number.

In addition to sending spam messages to mobile phone users, "pseudo base stations" illegally occupy public mobile communication frequencies and partially block public mobile communication network signals, which not only causes mobile phone users to fail to use the services provided by operators normally, but also causes mobile phone users to frequently update their geographical locations, which makes the wireless network resources in this area tense and causes network congestion, which seriously affects the normal use of mobile phone users.
