Portable jammer are getting more and more attention in the military field

Perfectjammer has announced the launch of DroneCannon RW, a counterdrone jammer which is designed for use on remote weapon stations.

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 wifi jammer systems, affecting planes and ships.

US department of Homeland Security (DHS) operates autonomous drones patrolling over the USA-Mexico border, which suffer jamming attacks by border smugglers, mainly the drug cartels," said Gai Mar-Chaim, Senior Partner at the management consulting firm POC. "The DHS gives high priority for lightweight anti-jamming solutions for this challenge, and GPSdome is the only commercially available solution that weighs less than 150 gram and consumes power less than 0.75 Watt.

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.

Also unique is that North Korea’s jamming is high power, sustained and from fixed locations – so it’s easy to identify where it’s coming from and the impacts. How much more difficult is it when signal jammer for sale are low power and are in a vehicle that quickly passes by? It took many months, and a concerted effort by several agencies, to locate the signal intermittently jamming an aircraft landing system at the Newark (EWR) airport in the United States. And who is to say if a dropped cell call or a glitch in an IT network is due to a jammer passing by or something else?

The use of wifi jammer in multiple domains

Jamming GPS and other satellite navigation systems is the classic asymmetric threat. It’s inexpensive, equipment is readily available and easy to use, and its effects are scalable from targeted local impacts to wide area strategic disruptions. At the same time it is very, very difficult to detect, especially when operated intermittently and/or from a moving platform, and its impacts are often attributed to other causes.

Prison cell phone 5G jammer have become a necessary addition to the arsenal of tools1 required for the safekeeping of inmates. Cell phones are becoming smaller every day, making them easier for inmates smuggle into facilities. This creates an even more difficult job for the already burdened correctional worker, however a cell phone jammer is the answer to restricting the inmates from using the cell phones for potentially dangerous activities. Cell phone jammer use can also force inmates to use prison approved / monitored phone lines.

Such tests could lead to the broader use of technologies like jamming inside prisons to immobilize inmate phones, which officials across the country have described as their No. 1 security threat.
