WiFi and Bluetooth frequency bands are commonly used to get access to the wireless internet. They use 2.4GHz frequency range for their work. Despite their unquestionable usefulness WiFi and Bluetooth frequencies may be used by the government for shady activities which might violate the privacy rights you definitely have. For example, indoor tracking that is spreading with the lightning speed. WiFi is actively used to track your location indoors, mostly through the hotspot location triangulation in a way similar to the mobile phone tower location triangulation. Bluetooth is also used for indoor tracking, particularly in Bluetooth beacons tracking technology. But wifi bluetooth jammer can protect your privacy and hide your location indoors.

Public wifi has serious security problems, the security of the network is deeply attacked by hackers, there have been many cases of using wireless network crime. In the face of such threats, you may need a signal jammer device to protect your information.

A new WIFI jammer has been designed to cut-off wireless LAN networks in a radius of 20 to 100 meters. This kind of device can transmit white noise signal in WIFI frequencies, 2400-2483MHz, and cut-off all Wireless network. Even the Bluetooth communication will be cut off when WLJ100 take action. This unit helps to prevent from unauthorized person to "leak" out confidential information.

Sometimes we don’t want others to know where we are, for example when we want to lie or don’t want to see someone. But the GPS on the mobile phone and the GPS on the car always expose our location. At this time, perhaps we need to use the gps signal jammer to get the effect we want.

The interference of GPS signals requires only a very small amount of interference energy in order to block the GPS signal temporarily or completely. Because the GPS satellites orbiting more than 20,000 kilometers above the earth's surface have a relatively low transmission power. Even a small GPS jammer can interfere with the signal within a radius of approx. 10 meters. This means that GPS tracking of vehicles with a GPS tracker is no longer possible. A variation of GPS jamming is so-called GPS spoofing. In this much more complicated method, a jammer sends wrong GPS signals, so it simulates the satellite signal to z. B. to lead enemy vehicles, ships or planes on the wrong course.
