Mobile phone signal jammers are used in many places, but they cannot be used immediately after installation. We still need to go through certain testing and acceptance to determine its effectiveness and ensure its effectiveness.

It is very important to ensure whether the mobile phone signal jammers can truly effectively block mobile phone signals. When purchasing a mobile phone signal jammer, testing is a very important step.

In all types of examinations, it has long been a common practice to install wireless signal jammers in each examination room. However, almost 90% of examination centers choose low-power shielding equipment when selecting equipment. Why did you choose this? There are often high-performance shielding devices on the market, but why are they so common in exam rooms? What if you don't know how to use a high-performance signal jammer?

The answer to this question can be analyzed from two perspectives: one is the product performance and application scenarios of the powerful wireless signal jammer itself, and the other is the design of the examination room.

Top prosecutors across the country are again calling on Congress to pass legislation that would allow state prisons to interfere with cellphone signals smuggled to inmates. According to lawyers, the devices allow people to plan violence and commit crimes.

“We simply need Congress to pass legislation giving states the authority to implement cell phone jamming systems to protect prisoners, guards and the public at large,” 22 prosecutors wrote in a statement. Wednesday's letter to House Speaker Kevin McCarthy and Senate Majority Leader Chuck Schumer.

Congressman David Kustoff (R-TN) and Senator Tom Cotton (R-AR) have introduced the Cellphone Jamming Reform Act, a bill aimed at addressing the issue of contraband cellphone use in federal and state prison facilities. The purpose of this legislation is to allow prisons to utilize cellphone jamming systems in order to protect inmates, guards, and the wider public from potential harm.

According to Congressman Kustoff, putting an end to the illicit use of contraband cellphones within correctional facilities will have an immediate impact on reducing crime rates, enhancing public safety, and relieving the burden on our overwhelmed correctional systems. He stresses that this act represents a crucial initial step towards tackling the current crime crisis faced by America. Congressman Kustoff expresses his pride in collaborating with Senator Cotton to introduce such pivotal legislation and urges fellow members of Congress to offer their support.

Ensuring the safety and security of both staff and inmates within correctional facilities is of utmost importance. Implementing stringent security measures is crucial to maintain control and prevent dangerous situations from arising. Sadly, the presence of cellphones in prisons poses a significant threat to this goal.

The Federal Communications Commission says illegal devices that block cell phone signals could pose a security risk.

The FCC has seen an increase in the sale of jammers devices that block cell phone calls, text messages, Wi-Fi networks and jammer GPS systems and could be used to wreak havoc in public places.

Cell phone jammers in the country's prisons are not enough to stop criminals inside from sending messages to others outside the prison.

That's the view of senior prison officials, and while network jammers (which they say can be used) are used to block cell phone signals in prisons, other interception techniques are needed for the system to be effective.

Let's give credit to the teacher who destroyed the phone signal in the classroom. This is just a place that needs them.

The news that Fivay High School teacher (and former professional wrestler!) Dean Liptak is in trouble for blocking cell phone signals in his classroom is completely the wrong reaction from the school administration (and let’s be honest, the government).

Of course, what he was doing was technically illegal. The FCC says: "The use of 'cell phone jammers' or similar devices (signal blockers, GPS jammers or text message blockers, etc.) designed to intentionally block, interfere with, or disrupt authorized radio communications is a violation of federal law." Oops, It's not even illegal to sell jammers in the United States, but they're easy to buy overseas (as long as the retailer doesn't get caught). The only legal purchasers of such equipment are government employees.

A signal jammer is a device that suppresses, interferes with or blocks radio frequencies, the use of which is generally illegal under the Communications Act 1934. This is primarily due to their ability to interfere with critical communications such as emergency communications, disrupt first responder communications, or interfere with maritime or aviation communications.

Under the law, it is unlawful for any person to "willfully or maliciously interfere with or disrupt the radio communications of any station licensed or authorized under this chapter or operated by the United States Government." Additionally, the bill prohibits the manufacture, importation, sale, offer for sale, transportation, or use of equipment that does not comply with the provisions of the bill.

We are convinced that this was an act of pure, unadulterated charity, uninfluenced by self-interest. Cellphone jammer maker CellAntenna Corp. is calling on U.S. lawmakers to change federal law to allow law enforcement officers to use cellphone jammers more broadly. We bet you can guess why too – and yes, it’s helpful in the fight against terrorism. Because as we all know, there are a lot of cell phone terrorists out there (in fact, for us, anyone we see with a cell phone is automatically suspect). CellAntenna said in a statement that adding cell phone jamming is "the first step in increasing profits to prevent IED attacks in the United States." How refreshing - a company with a social conscience.

The company is challenging FCC rules on cell phone jamming devices

A small Florida company is asking the Federal Communications Commission to change a rule that bans the sale of cell phone signal encryption equipment to local and state governments.

A resident of the town of Messanges in southwestern France could spend six months behind bars after unwittingly taking down telephony and mobile internet services in his neighborhood with a signal jammers.

Surprisingly, though, his actions were not malicious. He only wanted to prevent his teenage kids from using their mobile devices to go online after bedtime.

Bluelinx President Jeff Griffin said he is trying to sign up wireless providers as well as venues such as cafes and theaters. He says he hopes to start using the devices in the next few years. Unlike blocker device, he said, his call-blocking system is optional for cell phone users, who can turn it on or off.

Others have the same idea, including companies and researchers who develop or already sell devices that make phones unusable in certain places. Methods include drone jammer that interfere with cell phone frequencies, routing systems that mute cell phone ringtones at specific locations, sensors that detect active phones, and building materials that block cell phone waves.

Some people fear that cell phone jammers could disrupt phone service for law-abiding people close to prisons. However, modern jamming technology can be narrowly targeted to minimize disruption to people outside of prison walls.

It’s time to fix the federal regulations that prohibit jamming device technology and give prisons the tools they need to fight contraband.

Proliferation of wireless signal jammers

Communications jamming technology is falling into the hands of paramilitary groups and criminals

Our society is increasingly dependent on wireless technology. We wake up in the morning, check email via WiFi, unlock and start the car with the keychain in our pocket, and use our cell phones to make important calls on our way to work. When we go to a new place, we rely on GPS to guide us. Stolen or misplaced items can be located via LoJack or wireless AirTags. On a larger scale, much of our military and civilian infrastructure depends on wireless communications. Unfortunately, these signals are vulnerable to another type of wireless device: signal jammers.

In general, jammers simply disrupt existing wireless signals by flooding them with noise. By adjusting the jammer to a specific target frequency range and emitting a high-power noise, tone, or pulse, the jammer can interfere with nearby receivers trying to listen for that frequency. Traditionally, this has meant interfering with radio communications, but the same core principles apply to other types of wireless signals - cellular, WiFi, Bluetooth, GPS, and so on. Jammer ranges vary depending on the power and size of the device; In urban environments, small handheld jammers may be effective at a range of 100 meters or less, while large military-grade jammers can be installed in locations that easily cover hundreds of miles of open terrain.

Blocker CDMA GSM 3G 4G

Since January 1, 2018, importing and owning a jammer has been strictly prohibited in Switzerland and the countries of the European Union. The regulations for these devices, which are also known as "signal blockers" or "jammers", have been tightened up because the ban previously only applied to placing them on the market and using them. Jammers can be dangerous because they block all cell phone traffic, making emergency calls impossible. Most of the time, advertisements for these types of devices are deceptive: they give the impression that their use is legal, and fail to make it clear that even possession is illegal.

Tom's Guide tested an incongruous object: a cell phone jammer hidden in a pack of cigarettes.

There are various models, which are said to have a radius of action of 5 to 50 meters, and are sold for between 50 and 200 euros. The tested one is quite economical: 80 euros for a radius of 8 meters. Vicious: "Its makers have resized [the box] to make room for the two actual cigarettes in the pack".

The appearance and legitimacy of the product are not as good as it should be. "One thing's for sure, it didn't pass customs," the tester noted.

But why buy such a device? A salesperson interviewed offered some explanations: Some people disrupt communications in public transport, some teachers want quiet in the classroom...
