To avoid false base stations and spam bots, we recommend that you recommend a signal jammer. Different types of jammers for different customer groups. For individual customers, use a portable signal blocker if no target is set. For example, people know this place is unusual, but they have to go to a fake base station ... maybe this is the only way to go home. You can provide error filtering for portable signal jammers in order to obtain information for other types of customers, and we will make recommendations based on different needs. For different interference targets, there are various signal blockers, such as 2G, 3G, 4G, Wi-Fi, Bluetooth, GPS, etc.
