Cell phone jammer are increasingly needed in American prisons

Unlike previous events when authorities used jammers to cut off telecommunication signals, Department of the Interior and Local Government (DILG) officer-in-charge Catalino Cuy said the government would not request telecommunications companies to suspend their operations at the venues of the Association of Southeast Asian Nations (ASEAN) summit.

“That is also part of the directive of the President to minimize inconvenience. It is true that when network signals are gps jammer threats of remote detonation will be lessened, but we took it upon ourselves to check using our personnel and K-9 units,” Taas explained.

If South Carolina prisons were able to use cellphone signal jamming technology, an inmate would not have been able to escape from a maximum-security prison last Tuesday, state officials say. State Law Enforcement Division Chief Mark Keel and Gov. Henry McMaster on Friday echoed Stirling's frustration with the federal government on changing policy to allow the signal jamming.

As they await legislative relief from the problem, corrections officials are using various technologies that detect and find cell phones. Both high-technology and low-technology approaches are being tested and used. Several agencies have installed sensors that detect and find cell phones when in use. One such device tested in a Pennsylvania prison signaled cell phone location to within four cells on two tiers. Some sensors can even detect cell phones that are turned off, but they only work when in close proximity to a phone, cost between $15,000 and $20,000, and require trained staff. Others use new detectors that can identify nonmetallic objects to conduct searches. For smaller facilities, the use of specially formulated paints and coatings that block radio frequency signals may help.

“On January 17, BOP will test micro-jamming and evaluate whether we can use that new technology in prisons without disrupting services in the surrounding area," Rosenstein told a conference of state and federal correction officials in Orlando, Fla. The Justice Department micro-drone jammer test is the agency's latest effort to crackdown on phone use. In August, the Justice Department asked Federal Communications Commission regulators to come up with a way to stop inmates from using contraband cellphones, according to the Associated Press.

South Carolina Department of Corrections director Bryan Stirling was at the meeting representing for S.C. Stirling said this is the first time prison officials, the FCC and the Department of Justice have sat down to discuss solutions to fix the issue of cell phones in prisons. A solution that Stirling has been fighting for over the years is prison cell phone high power jammer, “I am confident that micro-jamming or jamming in general will work and if the industry wants to give us other solutions to this problem, we’re willing to listen and want to work with them on that,” Stirling said about cell phone jamming.

Application of signal jammer in medical field

A total of 508 young people in the county were admitted to the county physical examination station for physical examination, and the physical examination was orderly.

Ledong county, the county government workgroup to county, head of the armed forces or by a medical related events and check the conscription examination, and to draft a medical field by county public security special police brigade to stand guard on duty, adopt closed management, troops orderly organization for youth to participate in the examination, the field installation and practice highly mobile phone shielding jammers.

The relevant person in charge of ledong county, said the draft work is a serious political task, is to strengthen national defense and army building is an important work, especially in the current international situation is grave and complicated case, conscription work involved departments and personnel to obey the work discipline and work discipline, just open, honest conscription, guard a pass strictly, practical and good comprehensive quality excellent young selected, for troop supply high quality personnel.

The application of cell phone jammer in the field of security

According to foreign media reports, Nissan (Nissan) has demonstrated its weapons against the latest driver distraction - a prototype on can be installed in the future car compartment, is reportedly can block cell phone signals, caused greatly reduced cell phone distractions.

Nissan called it the gsm jammer, and demonstrated the concept on its small crossover vehicle, Juke. The compartment is in the arm of the car, surrounded by a Faraday shield that blocks all mobile phones, bluetooth and wi-fi signals. If the driver puts his cell phone in a cubicle, the device will be completely disconnected and silent, eliminating the possibility of distraction.

Of course, in order to achieve the same effect, the driver can also turn off the phone and put it aside. But nissan said the "signal shield" was designed to provide drivers with a choice when driving, rather than turning off their phones.

Data from RAC, a British road-rescue company, provides theoretical support for the development of a "signal shield back". Data from the RAC show that the number of drivers operating mobile phones during driving has risen from 8 per cent in 2014 to 31 per cent last year. The problem is not just that drivers text and call when they drive, but that if the phone is within reach, the notification prompts the driver to look at the phone.

Nissan has reportedly modified the signal shield to meet the needs of drivers who want "digital detox" but prefer to listen to music while driving. They can still use the phone via a USB or auxiliary port wired connection. Nissan says the shield is also easy to switch on so that the driver can easily reconnect to the phone as needed.

North Korea developed its GPS blocker capability in response to GPS-guided weapons

The country maintains a regiment-sized GPS signal jammer unit near the capital of Pyongyang and battalion-sized units near the demilitarized zone. Jamming in 2012 was traced to the town of Kaesong, just over the border.

North Korea reportedly purchased truck-mounted GPS cellphone jammers from Russia with a range of thirty to sixty miles, and in 2011 was reportedly at work on even longer-range jammers. Sixty miles is more than enough to jam the greater Seoul metropolitan area, home to half of South Korea's population.

South Korean civil aviation is particularly vulnerable to jamming because Incheon International Airport—which serves the greater Seoul metropolitan area—is close to the border with North Korea. Incheon is only 23 miles from the demilitarized zone. 49.2 million passengers passed through Incheon in 2015, making it one of the busiest airports in the world.

This device sends high amplitudes of emp to destroy nearby devices, be sure to have fun using this, but be careful this high power jammers involves thousands of volts which can lead to heart attack or death even.

The problem is that many potential adversaries drone radio frequency jamming

Such as the Chinese and the Russians, have developed advanced digital radio frequency memory (DRFM) jammers. These jammers, which effectively memorize an incoming radar signal and repeat it back to the sender, seriously hamper the performance of friendly radars.

Worse, these new jammers essentially blind the small radars found onboard air-to-air missiles like the Raytheon AIM-120 AMRAAM, which is the primary long-range weapon for all U.S. and most allied fighter planes.

ight now, the Defense Department—led by the Navy—is working to increase the range of the AIM-9X version of the Sidewinder by 60 percent to give the Pentagon’s fighter fleet some sort of counter to the jamming problem. 

This official added that future weapons would be far better at countering enemy jamming—so much so that future fighters will not need to have the sheer speed and maneuverability of an aircraft like the Raptor. “I think top end speed, super cruise, and acceleration will all decline in importance as weapons advance in range and speed,” he said.
