GPS is weak in radio waves, and even very small output can cause interference, especially due to the unintentional interference of radio waves, the bandwidth is very narrow. After receiving and decrypting GPS signals, it transmits fake information embedded in the signals as well as GPS jammer such as the original GPS signals. Because it's a weak radio wave, it could jam anyway.
It seems that the satellite communication system cannot be used. Every mobile phone company faces a difficult management problem. In cinemas, there are usually phone companies that sponsor them and ask advertisements to turn off their phones while they are watching. There are also concerns that mobile jammers could be abused. Unethical retailers may abuse the equipment.

Use electronic countermeasures against mobile phones. As phones become more popular, it seems, GPS interference may become more necessary. I emit stronger radio waves at the same frequency as a cell phone base station. It mimics the base station and sends empty messages to my phone, forcing me to leave the service area.
Radio interference was confirmed by someone in the time zone between commuting in the relay tower of a mobile phone and returning home. We seem to admit that the communication interference devices are used to gsm jammer with people around us. The scope for rejection can be small. The WiFi bluetooth jammer also blocks radio waves in the 1800mhz (1.8ghz) band.
