　　GPS finds major use in most equipment and systems to provide location information instantly both in civilian and military applications. These devices use the signal received from a minimum three GPS navigational satellites or more to calculate the location information. The use of GPS Systems helps terrorists to navigate both on land in mountains, jungles or desert terrain thereby providing them with a high degree of mobility and action capability. Availability of UAVs or drones with GPS capability also provides capability to terrorists to have surveillance of potential target sites for reconnaissance. This provides them the capability to cause death of both civilians and security forces as well as destruction of property and infrastructure giving them high visibility for their cause. There is extensive use of GPS in military equipment and systems both on man-pack and vehicular basis enable forces to move accurately during operations both during day and night.

　　Type of GPS jammers is Area Protection System against Satellite Navigated Hostile Threats which is a system designed to protect specific locations against missiles guided by GPS. It will effectively protect a well defined area from ground and sky threats while it will not, in any way, affect normal operation of navigation services outside this area. This is very useful to protect important locations like power generation facilities, national government or military headquarters or other critical sites from attack using GPS guided weapon like missiles or bombs.

　　Using triangulation, GPS can deliver the location to the receiver within centimeters of its exact spot.

　　It is important to note that GPS radio mobile signal jammer use a specific frequency. There are actually two major frequencies that GPS work on: one is for public, non-military use (1575.42 MHz) and one that is used solely for the US military (1227.6 MHz). Because GPS is nothing more than radio waves, these waves can be jammed, though technical devices and expertise are needed for that purpose.

　　GPS jamming is a continuing threat. A detailed understanding of how the available jammers work is necessary to judge their effectiveness and limitations. A team of researchers from Cornell University and the University of Texas at Austin reports on their analyses of the signal properties of 18 commercially available GPS jammers.

　　Many more likely go undetected each day. In 2009, outages of a Federal Aviation Administration reference receiver at Newark Liberty International Airport close to the New Jersey Turnpike were traced to a $33, 200 milliwatt GPS jammer in a truck that passed the airport each day. And in Germany, some truck drivers have been using jammers to evade the country’s GPS-based road-toll system.

　　We all know that our wi-fi enabled devices can occasionally just lose a signal. Chances are, that’s a result of an unintentional interruption in communication. It doesn’t necessarily mean that someone’s lurking nearby, purposely disrupting the device and causing you to lose your signal.

　　However, when a cell phone jammer is being used, it can block any device within a certain range from connecting and communicating. Whatever device is using the same frequency, the jammer can prevent any incoming or outgoing communication.

　　The way we communicate has changed a lot over the years. From handwritten letters to electronic e-mails to smoke signals and text messages, the way we exchange messages have developed so much thanks to the help of technology.

　　Probably one of the most ground-breaking inventions in the communications field is when the wireless signal transmission was discovered. As expected, this development came with a pair—in this case, the science of signal jamming. To explain it simply, signal jamming happens when a device’s frequency collides with another signal of the same frequency but at higher power. When this happens, the receiving device will not be able to process signals properly and stop functioning correctly.

　　The act of jamming signals was widely used during World War II and the Cold War. Besides using it to disrupt messages from reaching their intended countries, jamming of broadcast stations was also propagated back then. During the Cold War period, the broadcasters from the Soviet and the West even battled in a “power race” in which the mobile phone jammer worked to increase their transmission powers.

　　The situation started changing at the end of the Cold War. As the Soviet Union fell from power, the Western forces gained more traction and control over innovation and technology in general. However, with no need for “signal battles,” signal jamming was also classified as an illegal act among many countries, with the exception being for government, military, and defense applications.

　　India NAGPUR: Sadar police on Wednesday arrested one Deepak Ledwani, a resident of Jaripatka, for running away with a signal jammer put on his four-wheeler by Nagpur traffic police.

　　Police constable Sayed Ahmed attached with Sadar traffic zone on Tuesday put a tyre jammer on a wrongly parked car bearing number MH-31-FA-3911 on Mount Road, to ensure the driver was forced to pay a fine for traffic violation.

　　The Khadak police have launched an investigation after a scooter, which was impounded and fixed by a jammer by traffic constables on Tuesday night and parked alongside the Shivaji Road, was found missing on Wednesday morning.

　　All states and Union territories can now secure Central funds for buying body worn cameras for their prison staff to capture incidents of indiscipline and violence in jails and also for installing technology-based mobile phone jammer solutions to block unauthorised use of cell-phones by the inmates.

　　As part of the modernisation of prisons project, the ministry of home affairs shall offer grants in aid to the states for a period of five years starting with the current financial year, for deploying modern-day security equipment in prisons for their enhanced security and also to facilitate the task of reformation of prisoners through correctional administration.

　　In the modern age, most of us rely on technology for work, leisure, and convenience. This means most of our lives exist in an online space as we leave traceable footprints passing through. Anytime we use a map feature to get anywhere or log onto public wifi, we are instantly susceptible to data farming, tracking, and more.

　　Here at Jammer Perfect, we offer a wide range of products to protect yourself in a technological age. With a multitude of professionally crafted GPS jammers for sale, we have devices to cover your needs.

　　Once you’ve bought the WiFi jammer and ensure your router is functioning on the correct channel, you can set up your WiFi jammer. How you need to set up your wifi blocker will depend on the model you’ve chosen.

　　Some basic WiFi blockers can fit in your pocket and run on a battery. These jammers are great for keeping your jamming abilities portable and functioning wherever you go. This is especially beneficial if you plan on using your jammer in other places, such as at work or in a hotel.
