The school blocked the GPRS, 3G, and 4G networks of all operators during class, and the mobile phone signal is normal. How is this achieved?

Answer
It should be that the school has installed wifi jammer to prevent students from playing on mobile phones during class and surfing the Internet to delay their studies. If there is communication with the operator, the operator may also adjust the power of the base station signal near the school.
