After three years of meticulous work, the BQX-7B smartphone signal detection and shielding machine is also known as the magic machine in the cell phone jammer field. The BQX-7A smartphone signal shielding machine can be shielded for a long time, more energy-saving, no radiation The seven-channel frequency hopping transmission design ensures that the uplink frequency will not be affected and the base station will not be interfered with

At present, some technologies on the market are mainly concentrated in the frequency band that the walkie-talkie can receive. Some people with ulterior motives have also developed a transmission system that can break through Block Telemarketing Calls On Cell Phones based on the walkie-talkie frequency band. Whether it is exam cheating or other illegal uses such as eavesdropping, they are all targets of such communication systems.
