Why choose small jamming device?
Based from the original successful gsm jammer, the mini mobile handset blockers bring us more convenience than before. Its handheld design makes it possible for you to become carried anywhere anytime. Could hold it with you or put it into the pocket. Wherever you go, a holiday paradise or a sacred old town, individuals take another.
Cell phone jammer are transmitters designed to interfere deliberately with licensed services operated by mobile carriers, including 2G (GSM), 3G and 4G (LTE) networks and equivalent services such as mobile WiMAX.
WiFi signal jammer is effective if you are working with sensitive data away from work or your home, like a hotel or some other more public space. With up to two hours of battery life on full charge, it’s also ideal for people who feel more comfortable with a bit of a barrier between themselves and other people’s devices.
GPS signal jammer are usually small devices that plug into a vehicle’s lighter port and emit radio signals that overpower or drown out much weaker signals such as GPS or others. Although GPS jammers are illegal in the US, they are easily available online and are becoming more and more common as the use of fleet management tracking systems increases.
A major source of the GPS jamming will be Red Flag 18-1, the first phase of the air war games staged every year from Nellis Air Force Base in Nevada, with events ranging as far north as the Seattle air traffic control area. Electronic warfare aircraft, including the Navy’s EA-18 Growler and the Air Force’s EC-130 Compass Call, will play a role in shutting down the satellite navigation system for everything within as large as a 450 nautical mile radius.
GPS Jammers work by producing a white noise radio signal that is transmitted around the same frequency of the GPS satellites this can block out the signals to GPS tracking devices and navigation systems. A GPS jammer is easy to build. GPS signals are relatively weak and centered around frequencies of 1.0, 1.2, and 1.5 GHz, which are in the microwave spectrum. Simple emission of microwave energy in the vicinity of a receiver will mask out the weak signals transmitted by satellites (which are ~20k kilometers away) and render the GPS unit ineffective.
