Civilian GPS jammers are only good up to ten meters.

Bluetooth jammers are integrated with multi-functional jammers which is able to jam Wi-Fi signals and video. Wireless land are network signals, Bluetooth devices, and video transmitting, can be disabled and interfere with by these Bluetooth signal jammers.

These signal jammers are relatively low priced and this is the reason why it has gained popularity and is used repeatedly.

You can grab these cook signal jammers on the web. A simple cellular phone signal jammers usually costs less than fifty dollars for the cheapest ones and a little less than a hundred and fifty for the more expensive ones.
