For network jammers, most people call them differently, but their functions are the same. It usually covers the area where the signal needs to be shielded. Basically, a uniform and uniform distribution scheme is adopted to ensure coverage at every corner. Under the new digital signal technology, the surrounding communication environment will not be affected. When the network jammer is turned on, the mobile phone will be shielded from communication in the area where the mobile phone signal is disabled.

At this time, signal shielding is particularly important. We can use a network jammer to shield.

Some people think that instead of using data networks, I use Bluetooth and Wi Fi. In fact, these networks can be shielded by network jammers. For a long time, we have added the frequency bands of Bluetooth and Wi Fi to the shields. Each network data, Bluetooth and wireless networks have different frequencies. Our network jammers include these and can shield the whole frequency band.
