A signal jammer is a gadget used to interrupt or dislocate radio signals. It is commonly used to disrupted cellular phones from receiving and transmitting signals. They are typically wireless and can be used in any location to disable cellular phones. It can also be used to interfere with wireless local area networks or WLAN which correspondingly lead to the development and manufacture of jammers like: Bluetooth jammer, Wi-Fi and wireless video jammers among many others. Hi-tech and sophisticated signal jammers can even jam satellites.

Signal jammer will have some difficulties in interfering with other electronic devices which are in good working condition. These jammers are also used and regulated by the government and are usually intended to jam cellular phone communication lines only. Similarly, they only damaged the receiving end of a cellphone call because it directly interferes with the cell phone and the base station itself. It has a reliably small electromagnetic wave and as such, it has no known damage to the human body as well as to the cellular phone itself. However, if the jammers are larger, like outdoor signal stations there can be health repercussions for such.

The cellular phone jammer is probably the most common signal jammer available. It disables and delays the cellular phone from receiving signals from its base station, by blocking radio waves. The basic one typically works in a 10 meters to 1 kilometer distance. But those involving outdoor signal stations which are larger with different base stations and positions can effectively jam the signals of any GSM and CDMA phones.

Another more commonly used is the GPS signal jammer. These are commonly used by the military to confuse GPS tracking for locations. Similarly, there are no homemade tracking systems like this. Civilians who make use of these jammers to hide or cover up his location and that of his vehicle should in case it is being tracked by a GPS receiver. A civil GPS jammer usually covers up to 10 meters only.

Meanwhile, a Bluetooth jammer is usually integrated with a multi-functional jammer which jams Wi-Fi and Video. It works by disabling and disabling wireless LAN, Bluetooth devices as well as video transmitting for privacy.

A simple cellular phone signal jammer usually costs around US $ 33-122. GPS jammer is priced between US $ 99 to 1.495 each. The price for Wi-Fi / Bluetooth jammer starts from US $ 199 while the multi function Wi-Fi and Video jammer starts from US $ 295. This relatively low priced gadget added to its popularity and repeated use.
