A GPS jammer is a device that blocks transmission by creating interference. There are various jammers on the market. This is a simple category of jammers.
Mobile phone jammer
Mobile phones are now in widespread use, and normal frequencies and common bands include GSM, CDMA, DCS, PCS, and 3G networks. Mobile phone jammers can prevent mobile phones from making calls or sending messages by blocking traffic signals to nearby stations. If you don't want to be disturbed by a noisy phone, or if you want to prevent your privacy from being stolen, a cell phone jammer is a wise and excellent option.
GPS jamming device
More and more people are experiencing the painful experience of being tracked and monitored by GPS trackers. So what they need is a GPS jammer, a device that can interfere with the operation of the GPS tracker. However, the GPS tracker has not only one frequency band, but a total of five GPS signal frequency bands. GPSL1 (1500-1600MHz), GPSL2 (1220-1230MHz), GPSL3 (1200-1210MHz), GPSL4 (1250-1280MHz). , And GPSL5 (1170-1180 MHz). GPS jammers can send their own signals at the frequencies used by GPS tracking devices. This will interrupt or block other GPS signals.
WiFi / Bluetooth jammer
WiFi and Bluetooth are a type of wireless technology that supports short-range data exchange from fixed and mobile devices using the 2.4G frequency band that can be used to send information and files. However, because the privacy of sensitive documents is used as the wireless Internet, it is very likely to be attacked by hackers and has a weak ability to counter hackers. On the other hand, like WiFi and Bluetooth, it has the ability to track your location and work principals so that others can easily see your privacy. In this case, WiFi blockers can play an important role in helping to eliminate potential dangers.
LoJack / 4G / XM jammer
The 4G signal jammer works to block the signal from the 4G phone and prevents the 4G tracking device from functioning and ensuring silent state. LoJack is used for infrequent location tracking and is often used to track motorcycles and certain advanced laptops. LoJack jammers are coming to prevent your privacy from being stolen. In addition, XM Radio, which is a satellite entertainment channel and allows you to listen to music, radio programs, news, etc., has been well received by students. XM jammers can block and apply XM radio signals. This will greatly help improve the efficiency of your class.
Wireless video / audio jammer
Audio jammers have the same principle as VCRs, and wireless cameras have the ability to block signals from audio recorders to achieve the goal of preventing the recording of words someone says. And when wireless video jammers are used, wireless loses its functionality. Wireless jammers and video blockers are good choices for business people and those who want to protect their privacy.
In addition, there are UHF / VHF jammers, remote control jammers, and military / prison jammers.
