cell phone jammer

Thieves can obtain illegal small radius cell phone jammer. Their sizes range from small portable devices to large briefcases. They transmit signals at mobile frequencies. This prevents the GPS tracking device in the vehicle from sending and receiving messages. The signals transmitted by these illegal devices form bubbles around the vehicle, very effectively "silent" tracking the device, no one knows what happened. This happened in Congress recently. Large jammers have been deployed throughout the U.S. Congress, which can effectively block all cell phone signals in the House of Representatives. He can track the equipment with three main requirements for anti-interference. First, the mobile phone signal jammer device must be able to detect signal interference. Next, he needs to send an urgent message to tell someone "I'm trapped". The third and most important thing is that you need to be able to send this emergency message at a frequency different from the blocking frequency. Beware of crooks-if there is no other unimpeded frequency, the solution will fail.

The development of the mobile phone jammer security industry is an inevitable product. This industry has a very important position. Jammers, also known as signal interference shielding, extend to signal interference, small radius cell phone jammer, ceiling jammers, power jammers, etc. The history of the first interfering devices is a few years ago, as long as their functions are used by some companies, such as interference. With the rapid development of science and technology, various functional interference devices have been developed. With the improvement of product quality, applications are expanding to hospitals, prisons, airports, libraries and testing centers and other industries.
