What are Signal Jammers and What Can They Do?

Signal jammers are used by those who want to interrupt or dislocate radio signals. The most common use of signal jammers is to disrupt cell phones from receiving and transmitting signals. It is easy to disable cellular phones with these signal jammers because they are wireless and they can be used in any location. Wireless local area networks or WLAN signals can also be intercepted by these signal jammers. Because of this ability to interfere with wireless local area network signals, manufacturers have also developed other types of jammers like Bluetooth jammers and Wi-Fi and wireless video jammers. If you have high-tech and sophisticated signal jammers, you can ever jam satellites.

If an electronic device is in good working condition, it will be difficult for signal jammers to interfere with them. It is not only individuals who use signal jammers, the government also uses these and regulars its use and they only use it for jamming cellular phone communication lines. It is only the receiving end of the cell phone and its base station that is affected by a signal jammer. The electromagnetic wave of a signal jammer is relatively small that it does not really have an effect on the human body or on the cell phone itself. With bigger signal jammers however, like outdoor signal stations, there can be health risks if you use them.

Signal jammers used to interfere with cell phone signal is the most common signal jammer available. The cellular phone is prevented from receiving signals from its base station, and this is done by blocking radio waves. The distance covered by this signal jammer is from 10 meters to a kilometer.

Another commonly used signal jammer is the GPS signal jammer. In order to confuse GPS tracking locations, the military uses GPS jammers. This type of tracking system cannot be homemade. Civilian makes use of these jammers to hide or cover up their locations and that of their vehicle if they don’t want it to be tracked by a GPS receiver. A civilian GPS jammer usually covers up to 10 meters only.

Bluetooth jammers are integrated with multi-functional jammers which is able to jam Wi-Fi signals and video. These jammers can interfere and disable wireless LAN, Bluetooth devices, and video transmitting for privacy.

The prices of these signal jammers and relatively low and that is why it is getting popular with people today and are used repeatedly.
