Interference devices have been used in various fields

A jamming pod is essentially filled with antennae and radar transmitters. This equipment is vital for a warplane to survive modern combat. The first fight of every mission — a bombing run, surveillance or dogfighting — is waged across invisible parts of the electromagnetic spectrum. Radar can overpower other radar, sensors can be spoofed with “ghost airplanes.” Having a fast fighter that carries this equipment on strike missions is at the core of what the Navy does.

For example, in the past, when we got together, we always talk face to face. And now, we look down at the phone screen. Various social software devours our lives. At any time, always do not forget to take pictures, upload to Facebook or every day concerned about the dynamics of others. Of course, the use of mobile phones in the classroom, loudly answering the phone in the restaurant, in the theater and church phone ringing is also common.

Well, that’s the theory. In reality, the EA-18s are carrying a system fielded in 1971. The ALQ-99 Tactical GPS jammer System in current use can’t keep up with the gear of modern enemies. It doesn’t have the power to overcome others and doesn’t have a wide enough the frequency range to handle all comers. They (probably) give off too much heat, making the airplanes easy targets for enemy heat-seeking missiles. Hence the billion investment in a Next Generation Jammer, which is expected to migrate to other warplanes, even some manned and unmanned warplanes outside of the Navy’s inventory. That makes this a potentially vast, lucrative project for Raytheon. This project gives them a big head start on the follow-on procurements.

There is no doubt that mobile phones play an increasingly important role in our lives and to a large extent changed our way of life. Compared to face to face communication, we began to prefer to communicate through cellphone. You can see the people who use their cell phones everywhere.

North Korea started “aggressively” 4G jammer the BBC’s new Korean language service on the same day it began, according to a report. It said during radio jamming, a loud noise is transmitted over stations so that listeners can’t hear the content. South Korean officials have previously said that North Korea used radio waves to jam GPS systems, affecting planes and ships. The BBC broadcasts are carried on shortwave frequencies from Taiwan and Uzbekistan, and on medium wave from Mongolia, 38 North reported. It said it wasn’t possible to determine if the medium wave frequency was also targeted by jamming.
