You're not the only one if the idea of a cell phone signal blocker sends images of a cunning Bond villain plotting in secret into your head. You guessed it because of this. In the US and most of the rest of the globe, it is forbidden to buy, promote, distribute, or use mobile signal booster jammers.
The FCC asserts that cellular and Wi-Fi Signal Jammer devices "pose serious risks to critical public safety communications, and can prevent you and others from making 9-1-1 and other emergency calls and also interfere with law enforcement communications" because they purposefully disrupt "authorised radio communications."A signal jammer is an electronic device that is designed to disrupt, block or jam radio signals within a specific frequency range. These devices have become increasingly popular in recent years and are used in a wide range of applications, from military operations to law enforcement, and even in private and public spaces. In this article, we will discuss how signal jammers work, their different types, and their uses. A signal jammer works by broadcasting noise or a signal that interferes with the targeted signal, making it difficult or impossible for the signal to be received. The jammer does this by generating radio frequency (RF) energy within a certain frequency range that interferes with the targeted signal.
To understand how a signal jammer works, it is important to understand the concept of radio frequency. Radio frequency refers to the range of electromagnetic waves that are used to transmit information wirelessly. This range of frequencies includes everything from low-frequency waves used in AM radio broadcasts to high-frequency waves used in wireless communication and radar systems.

Again, this is either a lack of will or knowledge.
"Thales's new jammers were tested by the prison administration of two institutions in the Paris region.Mobile phones are officially banned in prison...
But the prison administration seized more than 27,500 units in 2016.
A record - three times more than in 2016 - and "real plague; According to Isabelle Gorce, the head of the prison administration, in February, the mujahedin committee on oversight of the jihadist group said in the hearing of the national assembly.
Christiane Taubira, in writing in January, responded with a written response to the United Nations population and development board's question of "restrictions," "very expensive," which quickly became "obsolete," and in the face of technological advances, such as the transition from 3G to 4G, that would explain the regulation of the Seals.To address these concerns, a group of scramblers was established in 2016 by several industrialist working groups supported by the French defence industry group, Terrestre (GICAT).
Results: the new generation model is now being tested in two institutions in the Paris region, including Fresnes.
The legal issue of interfering devices is a frequently discussed topic, and in this article, we will try to focus on all the aspects worthy of attention.
Later, when the government began to realize that this might pose a threat to society, people decided that it would be better to restrict these types of devices for two reasons.
Firstly-it is difficult to tell people not to use these devices near the police station, and secondly-almost anyone can get one of these portable frequency blockers, even if he is a terrorist, it increases the chance of such an attack.
On the other hand, the same technology can protect public places from improvised explosive devices all over the world.But knowing this, we support the decisions of these governments, but we want to ask some very important questions.
Basically, the problem lies in the following points: How can we protect our privacy when we are not allowed to take the necessary measures to preserve it?
This means that the government should consider more factors and decide whether certain frequency limiters should be allowed.

Cell phone jammer using reasonsMobile phone jammer is the best tool to prohibit the use of mobile phones.
In addition, the mobile phone jammer can also allow your child to grow up in a good environment.
Why do people need to buy equipment that is actually very expensive or even illegal?
Now that the phone tracking is too easy, the information on the phone is not difficult to leak.
The school seems to allow you to use it by default.
At present, most schools have installed military jammer.
Cell phone signal jammer in prisonIn the battle to keep criminals from using contraband cellphones in prison, law enforcement may be a bit closer to having technology that could jam phone signals inside correctional facilities without affecting nearby communications.In January, Perfectjammer said its researchers installed the jamming technology in a utility closet adjacent to a 13-by-eight foot cell on the ground floor of the prison's housing unit, according to the study.
It successfully blocked cellphone transmissions in commercial bands between 700 and 2170 MHz, but did not disrupt commercial transmissions when monitored at 20 feet and 100 feet outside the cell, said the study.The data in the report will be used by the Federal Bureau of Prisons (BOP) and the Department to understand the efficacy of micro-jamming, conduct further evaluation of wifi jammer technology, and develop recommendations for strategic planning.Jammer testing and resultsThe test’s data show that the micro-jammer’s signal disrupted commercial wireless signals inside the prison cell, meaning that if cellphones were operating inside the cell, they would have been rendered inoperable.The microjammer targeted CMRS service indoors in a single medium-security prison cell.
Spectrum measurements of the jammer emissions were performed at two places inside the targeted prison cell and at two nontargeted nearby locations outdoors.
GPS jammer emission measurements were performed at each location with multiple measurement bandwidths and detectors across a frequency range of 300 MHz to 4.34 GHz.At the measurement locations inside the prison cell, measured differences in incident power between when the jammer was on versus off showed that jammer incident power levels were much greater than that of the ambient CMRS power levels.
For the outdoor locations where jamming was not intended, the jammer’s incident power was measurable at 100 feet from the building.
However, outdoors the incident jammer power levels were lower than the ambient CMRS levels.
In February, 2011,there was a conflict in Cairo.
The situation was very difficult, the streets were full of protesters and the police try to stop all the protest actions and ask people to leave the Tahrir Square so that the peaceful atmosphere could be recovered.To stop coordinated activities of protesters the government shot down the mobile connection in the whole city.
In a few hours it was restored but jamming devices for local GSM frequency blocking were used in places of big crowds like on the Tahrir Square and other epicenters of riots in Cairo.
Because of the usage of GSM jammers, the coordination of these groups via cell phones became impossible and the aggravation of the situation in the streets of Cairo was stopped.
Also the usage of cell phone jammers made appliance of radio-controlled explosive devices of radical protesters impossible.
Some explosive devices are activated via the signal of the mobile phone, and GSM jammers prevent the successful appliance of such bombs.A cell phone jammer is a device designed to block any signals that mobile telephone sends and receives.
