As the GPS satellite signal is weak, the GPS jamming device with an output power of about 2W is enough to jam the GPS signal in the vehicle about 10 feet away from the device.The recorder jammer can send jamming signals to the recorder to prevent it from recording conversations.The portable mobile phone jammer is small in size and only has a pocket size.The jammer can be put into a pack of cigarettes, so it is easy to hide.

There are also fears that terrorists will use these devices to disrupt air traffic and cause serious security and economic losses to the United States.GPS jammers can prevent GPS tracking devices from receiving signals, otherwise they will not be able to determine their position.These devices also pose a threat to airlines and U.S.troops stationed overseas.

This ensures a comprehensive defense against the communication guided by the transceiver operating in a short distance.The interphone jammer/radio jammer can block any interphone radio signal.As GPS jamming equipment falls into the hands of the enemy, the United States and the Allies may be seriously affected when launching ground and air strikes.

In Germany, it is believed that some drivers are using GPS jamming devices to avoid GPS based road tolls; Concept introduced for trucks in 2005.Wifi interferes with the device broadcasting power radio waves to disable communication between PCs or mobile phones and master stations that do not interrupt any connections.

The only thing more striking than GPS technology is its ubiquity.Bluetooth or wifi jammer transmits electronic signals at 2.4-5.9GHz, and interrupts all cordless networks and Bluetooth connections.Small workers may block Bluetooth and wifi signals.But these signals have also changed the industries you don't often think of, such as agriculture, manufacturing, and even aerospace.

These satellites also provide the position in orbit of all other GPS satellites.Mobile phones are like two-way radio stations.Similarly, signals close to mobile phones are likely to be interfered.Each GPS satellite is essentially an extremely accurate clock, which can broadcast the exact time of its location.

The jammer will also block the use of the Internet over Wi Fi networks, or even Bluetooth connections.Some models carry GSM, 3G, 4G and WIFI at the same time, so you can easily jam all mobile phone signals.Mobile phone jammers include gsm jammers, 3G jammers, 4G jammers and the latest 5G jammers.Mobile phone signal blocker also eliminate short messages, so students cannot send short messages to each other while teachers are teaching.

The jammer works well, even in an enclosed space.Jammers can also work from a distance or behind a wall.Personal mobile phone jammers can range from 10 meters to 100 meters.Larger cell phone jammers are more powerful and can range in miles.

Mobile phone jammer is a common tool, which is used to avoid transmitting mobile phone network signals to mobile phones, thus interfering with all mobile phones.Schools, meeting rooms, offices, cinemas, prisons, nightclubs and casino owners use cell phone jammer to prevent the use of mobile phones in buildings.

The necessity of mobile phone interference devices appears in these places.Once the GPS receiver knows the position and time of the satellite, it can see the exact distance to the satellite.When the receiver can compare the time of at least three satellites, it can know its position on the earth's surface.In temples, libraries, theaters and other social places, we sometimes meet people who do not understand the etiquette of mobile phones and call loudly.

wifi blocker are designed to interfere with wireless terrestrial systems and Bluetooth communications.Almost every mobile phone in the world has a GPS receiver.Environmental sensors, pipe controllers, and of course cars - even many vehicles without navigation systems have GPS receivers.This can be done using the GS M jamming device.

The outdoor Wi Fi jamming device looks like a panel antenna or Wi-Fi outdoor. Although most people may know that Global Positioning System (GPS) is a way to find a way to travel, its influence goes far beyond finding the best commuter route.Signals from GPS satellites have changed the industries you know, including aviation, shipping, and ocean navigation.Bluetooth or Wifi jammers may help people avoid criminals from disclosing confidential data.

Once turned on, the equipment will start to work, blocking any transmitted VHF (144-174 MHz) and UHF (420-480 MHz) signals within the range of 30~50 meters.The GPS jammers sends a radio signal with the same frequency as the satellite signal.More powerful jammers may interfere with GPS signals near the airport, causing security problems.They transmit their signals at the frequency used by the GPS tracking device, which can confuse or block other GPS signals.

It can also transmit audio signals to the recorder to confuse voice frequencies. Car thieves in the UK are now using the latest GPS jamming equipment to make stolen cars and trucks undetectable by law enforcement. This makes it impossible for the onboard system to determine its location and report to the GPS tracking center registered with the vehicle.
