In the United States, gadgets called cell phone signal jammer are becoming more and more popular, but the risk is also very small. Security experts say this is illegal and potentially dangerous.

San Diego (CBS 8)-Small tools called "phone jammers" are becoming more and more popular in the United States, but they also bring great risks. Security experts say this is illegal and potentially dangerous.

You can thank a man in Philadelphia who is tired of other cell phone passengers yelling on their phones in case of a sudden surge in the Internet caused by cell phone jammers. These devices can be purchased online at a price of between $40 and $1,000, which is the concern of some security experts.

Nowadays, even if you are an ordinary person living an ordinary life, almost everyone can suffer damage, such as being tracked and monitored by others. Therefore, there is very little privacy regarding their real-time location/activity. Therefore, it is time to take action and use gps signal jammer against these spies.

GPS jammers are devices specifically designed to prohibit the normal use of various GPS tracking devices. For this reason, many people can protect themselves without worrying about losing their secrets and privacy. It works like a mobile phone jammer, so it is very easy to use and install.

Feel the need to stay safe, and whenever you are worried about your safety, you can ask for help from a GPS signal blocker. But where should you go?

But there are some restrictions because the locker room or business office is completely different from crowded public places. For example, if you use this Apple Camera Deactivator, it will definitely make a lot of people feel embarrassed, they just want to take photos or take pictures to remember their friends. The same applies to gsm jammer, but it may vary from place to place (for example, movie theaters absolutely must have such equipment in order to make the visitor’s experience uninterrupted and thus get a greater experience).

When you are in a meeting and someone’s ringtone suddenly rings, even if you tell them to turn off their phone before the meeting, this kind of thing will still happen. To solve this problem, a mobile jammer was invented. If you need a more powerful blocking phone jammer, you can choose a high power jammer, which will improve the work efficiency of company employees and protect confidential data leakage.

The first use of electronic jamming countermeasures can be traced back to World War II. Radar-controlled artillery shot down many Allied aircraft. These systems use radar signals to block and track air targets and direct air defense firepower. When conducting critical joint operations, resistance forces place RF interference near these weapons. Video footage from news movies shows how the shells spun suddenly and fired randomly due to interference. The barrel designers were too arrogant and did not consider the possibility of interference, so they never used a "manual override" switch.

The operating frequency and signal strength of the GPS jammer are greater than the expected signal of the receiver. Therefore, if the jammer has enough power and a wide enough signal spectrum, it may block all receivers on one pedestal. Another method is to jam a copy of the expected signal and trick the receiver into receiving the interference signal instead of the expected signal.

Military officials declined to say whether GPS was in battle. But solutions have been developed to overcome this problem. First, the Air Force and Navy have electronic warfare aircraft that were modified in the 1990s to detect GPS jams, said James Hasik, co-author of "Precision Revolution: GPS and the Future of Air Warfare." Hasik added that military officials have also updated Raytheon’s "hazard" missiles so that they can identify GPS jamming launches.

China uses GPS to block the US military. Traffic jams and GPS spoofing are often classified by US officials as "electronic warfare" rather than "cyber warfare." We don’t understand why this is the case, because interference and deception will offset the equipment used by the end user, cut IT pathways and introduce false data. In various systems. For cyber fighters, detecting and preventing GPS blocking and phishing may be a shortcut.

Advanced technology has brought convenience to mankind. At the same time, it also brings threats. We must learn to protect ourselves in such an environment. Cell phone signal jammer that interfere with call signals have become popular abroad and have been sold in the Chinese market in the past two years. To avoid fraud, some GPS jammers have been installed in the classroom. However, for more and more citizens, the abuse of such devices will affect citizens' freedom of communication. Advanced technology may enter the computer and steal important information. We can also track some cars. For security reasons, please purchase mobile jammers via the Internet.

If you need to go out with a jamming device,they are your best choice. There are a various portable signal blockers here, such as portable cell phone jammers,handheld gps jammer,portable WiFi blockers.

The GPS Global Positioning System uses a number of orbiting satellites that transmit radio signals. The signal arrives at the GPS receiver to determine the positioning by triangulation. GPS can be found in individual handheld devices and cell phones, vehicle navigation and positioning systems, and small GPS tracking devices.

The position can be found by triangulation, a way of measuring three individual points in order to calculate the position. The vehicle's position is measured by three satellites in the vehicle's navigation system. With triangulation, GPS can transmit the position to the receiver with an accuracy of only inches.

The GPS signal is a radio signal with a specific frequency. GPS actually has two main frequencies, one for public, non-military (1575.42 MHz) and the other for the US military (1227.6 MHz). Since GPS is only weak radio waves, the use of GPS jammers can jam or twist these waves.

GPS jammers were originally created by governments, military organizations and espionage agencies. Its uses include confusing the enemy as to the exact location or where the enemy GPS missile or bomb will fall.

If you need a cell phone jammer, the design of portable type I recommend to you, it has the function of what you need, block phone signals, also has the characteristics of portable, make it much easier to carry it with you, let you can use anywhere in the outdoor, distribution car charger to make it work more convenient, not influenced by battery and can't use, you can charge on your car.

OKLAHOMA CITY - Thousands of illegal cell phones end up in the hands of prison inmates who use the devices to commit crimes. However, prison officials testified Monday that they are prohibited from using any of the best means to stop this - mobile phone jammer.

Prison officials from Oklahoma and South Carolina testified before an Oklahoma Senate committee about the effectiveness of cell phone jamming technology. Federal law prohibits government use of this technology, and the wireless industry opposes it.

Oklahoma confiscated more than 5,200 smuggled cell phones from inmates in the past year. While that's a decrease from about 7,500 seen a year earlier, the problem remains a serious problem, said Mike Carpenter, chief of security for the Oklahoma Department of Corrections.

Carpenter said a fight between rival gangs in an Oklahoma prison last month had rapidly escalated with the use of smuggled cell phones in melee prisons in several other prisons. One inmate was killed and more than a dozen injured.

"Do I think a (cell phone) jam would work? Definitely," said Carpenter.

According to Gerard Keegan, a spokesman for the Cellular Telecommunications and Internet Association, the wireless industry is against the use of cell phone jamming signals in prisons, largely because it is feared that it will block signals for legitimate users as well.

Instead, he says the group is supporting a "managed access" system, which uses technology to determine what signals are from smuggled phones in a prison so that steps can be taken to disable those target phones. He said the group also supports further testing of cell phone jamming techniques.

The federal law, according to which states may use jammers, is still pending in the House and in the Senate.

"My proposal is simple," US Senator James Lankford, R-Oklahoma, told the US Senate earlier this year. "To protect our guards, protect our families, and stop criminal activity in our prisons, let's block cell phones in prison."

Last year, federal officials at a federal prison in Cumberland, Maryland tested the portable signal jammer and said they could turn off phone signals in a prison cell while equipment operated normally about six meters away.

With a so-called wireless jammer, you can protect yourself from a position determination or secret eavesdropping. This misery can be of great importance under certain circumstances. Because the danger of being located by your own cell phone or being tapped during important calls is omnipresent and can have dire consequences.

GPS jammers have positive advantages

It is common knowledge that GPS tracking has many advantages. But this position determination also has some disadvantages.

Finally, the location determination also enables an assassin to locate the victim and carry out the planned attack. But even in less dramatic cases, GPS tracking has some negative aspects.

Many assassins have already used the possibilities of determining their position in order to find the potential victim at any time. In addition, many private individuals use their mobile phones to locate their partner because they are jealous and suspect unfaithful behavior.

Because if your own smartphone has been registered with a location service, it can be determined at any time where you are currently. In other words, if you tell your wife, for example, that you are going to work when you are actually having a beer with a few friends, it will be easy for the wife to let this lie open.

In addition, when visiting a friend of the opposite sex for the first time, some teenagers certainly don't want their parents to be discovered.

There is now a technology that prevents the location of a position: the GPS jammer

If you carry a so-called GPS jammer with you, the signals of the Global Positioning System will be disturbed, which makes it impossible to carry out GPS positioning. A jammer is able (through the jammers) to switch off the complete reception of the GPS satellites.

This technique has a side effect that can be viewed as both positive and negative. Because if a cheap GPS jammer has been activated, you will no longer be able to use the cellular network. So you always have to take into account that using a jammer also switches off your own cell phone traffic, as making calls with a cell phone is made possible by the radio frequencies that are disrupted by the jammer. But this can also be seen as an advantage. Because while some people complain about the lack of mobility, for others this is the real reason to buy.

The price of portable GPS jammer has been as low as tens of dollars a unit. It can suppress and interfere with the navigation and positioning signals of the US-made GPS within a certain range, so that weapons using GPS guidance systems can't hit the target. Currently, the US military is developing a brand-new positioning and navigation system. With this system, the US military can operate efficiently without relying on GPS.

The U.S. Army and other services rely heavily on GPS for timing, positioning, and navigation. Therefore, opponents of the U.S. military are upgrading and strengthening their anti-GPS capabilities. Over the years, in order to get rid of the military’s heavy dependence on GPS, several major US services have sought backup navigation technologies that do not rely on GPS systems.

According to foreign media reports, on July 6, 2017, the U.S. Army’s Rapid Capability Office issued a solicitation for information on “positioning, navigation, and timing alternatives”, calling on relevant companies to develop new navigation systems that can replace GPS systems to allow the Army’s ground forces Combat platforms and combat personnel of arms such as Army Aviation Corps can effectively fight with GPS signals shielded.

The GPS system is a global satellite timing, navigation, and positioning system built by the US military in the 1990s. GPS is also a basic combat facility that is completely controlled by the US military. After years of development, the US military and its allies have become heavily dependent on them in combat. The U.S. Army and its allies’ tanks and armored vehicles, various types of fighters, various surface ships and submarines, and many other combat platforms, as well as many precision guided munitions, mostly use GPS terminals. This allows the U.S. military and its allies to have Advantages in navigation and positioning.
