4G LTE cell phone jammer have become the mainstream of market demand

Cell phone jammers have been around since 1998. The devices can block signals in a room about the size of a movie theater. The jammer sends out a low-power, encoded radio signal or modulated radio wave.

WiFi signal jammer work in one of two ways. Some devices set their signal to the same frequency as pagers and mobile phones, cutting off communication between handsets and base stations. Others work as electronic filters that fool mobile phones into thinking there are no frequencies available to make or receive calls. Manufacturers of the devices say the jamming only affects the designated area (most radii are a couple dozen to several hundred feet) and works only on cellular transmissions.

As you know 4G LTE is a totally new signal of communication area. In recently market, there are little jammer can block its frequencies. Now the Perfectjammer's new electronic device will help you to achieve the goals. Furthermore, it not only blocks the latest 4G LTE frequencies, but also jams other frequencies. Having a compact device, all signals can be block in your hands. The small and compact device is easy to carry.Like a small cell phone, you can put it into your pocket and any bags.

The tide, however, may be changing. This past spring, both Hong Kong and Canada announced they would consider legalizing jammers in an effort to curb bad phone behavior in public. Around the same time, the leaders of India's parliament revealed they had already installed the devices to avoid interruptions during sessions.

Communication GPS signal jammer technology from Russia

The Russians began jamming some smaller U.S. drones several weeks ago, the officials said, after a series of suspected chemical weapons attacks on civilians in rebel-held eastern Ghouta. The Russian military was concerned the U.S. military would retaliate for the attacks and began jamming the GPS systems of drones operating in the area, the officials explained.

Jamming, which means blocking or scrambling a drone's reception of a signal from a GPS satellite, can be uncomplicated, according to Dr. Todd Humphreys, the director of the Radionavigation Laboratory at the University of Texas at Austin.
