Non-kinetic counter-UAV measures function by interrupting or intercepting communication signals. These techniques often result in the drone falling rapidly, which is not advisable in crowded areas. Nonetheless, they can be effective in other environments. It is essential to be aware of the legal restrictions in your country regarding drone countermeasures, as drone jammers and spoofers are illegal in the United States. Let us examine some different non-kinetic C-UAS methods.
Jammers operate by producing electromagnetic noise on the radio frequencies that drones utilize for their operational and communicative purposes. This noise effectively interferes with the communication between the drone and its operator. The frequencies generally involved are 2.4 GHz and 5.8 GHz, which are public frequencies that are not specifically assigned. This design prevents the jammers from causing interference with manned aircraft, cellular networks, public broadcasting, or other designated radio bands.
Jammers can be either stationary devices that are mounted or integrated into highly mobile, gun-like systems, enabling the safe retrieval of drones from the air.
The Federal Communications Commission (FCC) has indicated that drone jammers are not authorized for use in the United States.
Employing a 'cell phone jammer' or any related device to intentionally obstruct, disrupt, or interfere with authorized radio communications is a violation of federal law. These devices, which encompass signal blockers, GPS jammers, and text blockers, pose a serious threat to essential public safety communications, potentially preventing individuals from making 9-1-1 and other emergency calls. Furthermore, jammers can disrupt communications vital to law enforcement activities.
Utilizing a jammer in the United States can result in severe financial penalties, the seizure of illicit equipment, and criminal sanctions, including the possibility of imprisonment.

Operating a vehicle while using a mobile phone can pose serious threats to life. Numerous studies have illustrated the significant dangers that arise when drivers use mobile phones while driving. The act of engaging with a mobile device distracts the driver’s eyes from the road. In addition, GPS signal jammers can be readily impacted by electronic components, just as mobile phone signals can be disrupted.
GPS signal jammers can block signals within a certain range, causing all communication devices within the range to lose signals. Installing a GPS signal jammer on a car allows buyers to easily find their cars on the GPS monitoring management platform. As we all know, such a good product has also been found loopholes by criminals. If you buy a GPS signal jammer from the Internet, then when stealing a car, there will be no signal in the car, and the vehicle will be offline on the service platform, as if its whereabouts are unknown, and no matter how you find it, you can't find it. This is one function of the GPS signal jammer. Another main function of the GPS signal jammer is to cut off the signal of hidden GPS tracking devices and protect our private information.
Legal use of GPS signal jammers, some criminals like to use GPS signal jammers to steal cars, causing some social problems. For example, some ultra-long standby GPS locators can only call once a day, and after waking up, they will immediately return the precise positioning information of the vehicle to the buyer's network platform, and then go into sleep mode. Without any signal, car thieves can't detect it at all! In addition, it does not require wireless network installation. There is no wiring on the surface of the machine, and it can be placed anywhere on the vehicle (if it is not required to be placed in a signal shielding area). The project security is very hidden. Of course, GPS blockers equipment is mainly used to defeat hidden GPS tracking kits.
Do you believe that high-level meetings within your company do not provide enough privacy? Are you looking for ways to prevent being recorded by others in public or at home? The most effective solution to this issue is to use a mobile phone signal jammer.
The functioning of a mobile phone jammer kit is based on the interference or blockage of signals from nearby mobile phones, which stops these devices from transmitting or receiving information. Nonetheless, there are various aspects to consider when opting for a mobile phone jammer.
The initial factor to assess is the price. The cost is influenced by the level of technology of the jammer you require and the additional features you wish to incorporate. Typically, mobile phone jammers that simply block signals are more economical than other types, including wireless and remote control jammers. It is also worth noting that a wider coverage area generally leads to an increase in price.
Alternatively, before you proceed with the purchase of a cell phone signal jammer, it is crucial to understand the operating frequency of the device. In the United States and Canada, for example, the frequencies are 850MHz and 1900MHz. Hence, it is essential to pay attention to this aspect to avoid acquiring an unsuitable cell phone signal jammer.

New Delhi: Chinese mobile signal jammers have made their way into the markets of the city, violating the Cabinet Secretariat's prohibitions against the use and sale of such devices by individuals. Recently, law enforcement officials confiscated an illegal jammer from Palika Market in Connaught Place.
The police are investigating the source of these illegal jammers and tracking down potential buyers, especially in view of the recent blasts in Prashant Vihar in Rohini and the perceived threat of terrorism. The police suspect that there could be a larger network involved in importing such mini gps jammer to disrupt communications. It is worth noting that Palika Market and New Lajpat Rai Market are known for selling cheap electronic products, including pirated and counterfeit products.
On October 24, the police in Connaught Place arrested a shopkeeper for illegally possessing a mobile signal jammer, as part of an operation prompted by increased security concerns.
The individual known as Ravi Shankar Mathur, who is 58 years old, was located with a jammer of Chinese origin that is capable of jamming mobile phone signals. The police discovered this device, in addition to ten antennas and an electrical connecting wire, at a shop in Palika Bazar.
When interrogated, Mathur did not provide any documentation, including bills or licenses, to validate his claim of possessing the gsm blocker. He alleged that he had acquired the device from the New Rajpath Rai market for Rs 25,000, with the intention of reselling it for a higher value.
A memorandum detailing the seizure listed the confiscated items, which included a silver-grey jammer measuring 30x13 cm, equipped with 10 antenna jacks that are compatible with various mobile technologies, as well as a manual that elaborated on the device's features and installation instructions.
The Department of Telecommunications has been made aware that it will initiate further investigations into Mathur and will take the appropriate legal steps against him.
The Attorney General of Georgia has formally requested information under the Freedom of Information Act (FOIA) from a federal agency about the existing ban on cell phone jammers in Georgia's prison system.
Attorney General Chris Carr’s office said this week that Carr filed a FOIA request with the Federal Communications Commission (FCC) following the agency’s “continued refusal to allow state and local law enforcement to jam the signal of contraband cellphones in prisons and jails.” Specifically, Carr is seeking all inter-agency correspondence related to his June 4, 2024, letter urging the FCC to allow for states to use cell phone jamming technology in prisons and jails. Carr is also seeking all documentation related to the FCC’s response denying the State’s request and information regarding the use of cell phone jamming devices at select federal prisons.
Carr noted in a press release, "Law enforcement is currently facing difficulties in addressing the issue of contraband cellphones, largely due to an obsolete policy that the federal government refuses to reconsider. The solution is straightforward: by blocking the signals of these unauthorized devices, we can help mitigate the violent crimes that are coordinated from within prisons and enhance our overall public safety initiatives. If the Biden administration is not inclined to collaborate, they should allow our officers to fulfill their duties without obstruction."
The FCC has instituted a ban on the use of cell phone "blockers," a restriction that is also applicable to state and local governments. However, in correctional facilities throughout the country, contraband cell phones are being utilized to plan and execute violent attacks and other criminal activities, which poses a significant threat to correctional officers, visitors, inmates, and the public at large.
An incarcerated leader of the notorious "Yves Saint Laurent Squad" street gang used a contraband cell phone to order a hit, which led to the death of an 88-year-old veteran from Georgia. In North Carolina, a gang leader similarly ordered the kidnapping of a prosecutor's father through the use of an illegal cell phone while in prison. Furthermore, in California, prison gangs have exploited contraband cell phones to facilitate drug trafficking and to arrange murders within the correctional facilities.
In his June 2024 letter, Carr notes that the FCC’s current policy relies on a decades-old statute. He further states: “Nothing in the language of 47 U.S.C § 333 prohibits the FCC from revising its position to allow state agencies to use cell phone jamming devices in prisons. In fact, the United States Bureau of Prisons has recognized the potential value of cell phone jammers already and is permitted to use jamming devices at several federal penitentiaries, including at least one in Georgia.”
In January 2023, Carr, along with 21 other attorneys general, pressed Congressional leaders to pass legislation that would grant states the authority to implement a cell phone jamming system in correctional facilities.
The Carr’s Gang Prosecution Unit has established a partnership with the Georgia Department of Corrections (GDC) to investigate and prosecute those currently incarcerated who are suspected of involvement in criminal gang activities, particularly in relation to discussions about the packaging and shipping of contraband items into a GDC facility.
