Radio jamming is the deliberate blocking of or interference with wireless communications. It is a growing problem, especially for emergency services, and can be a matter of life and death. Jamming devices are illegal in the US, and their sale, marketing, and operation are prohibited by federal law. Despite this, radio jamming is on the rise, and those who use jammers can be difficult to catch. Law enforcement officers can file a complaint through the FCC Enforcement Bureau if they require assistance with jamming or interference.

Radio jamming is illegal in the US and can carry fines of up to $112,000 and prison time
Radio jamming is a violation of federal law in the United States. Federal law prohibits the operation, marketing, sale, manufacture, or importation of any type of jamming equipment that interferes with authorized radio communications. This includes cellular and Personal Communication Services (PCS), police radar, and Global Positioning Systems (GPS).
The use of a phone jammer, GPS blocker, or any other signal jamming device designed to intentionally block, jam, or interfere with authorized radio communications is illegal. This applies regardless of whether the jamming takes place within a business, classroom, residence, or vehicle. Local law enforcement agencies do not have the independent authority to use jamming equipment, with a few exceptions for federal law enforcement agencies authorized in accordance with applicable statutes.
The penalties for radio jamming can be severe. Under Section 501 of the Communications Act, violators may face substantial monetary fines of up to $112,000 and criminal sanctions, including imprisonment. Additionally, Section 503 allows the FCC to impose forfeitures for willful or repeated violations, and Section 510 authorizes the seizure of unlawful equipment.
Radio jamming poses serious risks to public safety communications. It can prevent individuals from making emergency calls and interfere with law enforcement and first responder communications, potentially delaying their response to urgent situations and endangering lives.

Radio jamming is the deliberate blocking of or interference with wireless communications
The use of radio jamming devices is prohibited by federal law in many countries, including the United States. This includes the operation, marketing, or sale of any type of jamming equipment that interferes with authorized radio communications, such as cellular networks, police radar, and Global Positioning Systems (GPS). Local law enforcement agencies do not have the independent authority to use jamming equipment, however, in certain limited cases, federal law enforcement agencies may be authorized to do so.
Despite the legal prohibitions, radio jamming devices are available for purchase through illegal means, such as the black market, and can also be built at home. These devices can block data delivery at a distance of up to 15 meters without barriers, and more powerful stationary jammers can have a range of 100 meters. The availability of these devices has led to an increase in radio jamming, particularly in emergency response situations, where it can delay the arrival of emergency services and put victims in harm's way.
To combat radio jamming, countermeasures have been developed, such as anti-jam antennas, and the use of spread spectrum modulation to resist the effects of jamming. Additionally, individuals experiencing jamming or interference can file a complaint through the FCC Enforcement Bureau's Public Safety Interference (PSIX-ESIX) Portal or contact the FCC's 24-Hour Operations Center if the jamming poses an imminent threat to safety.

Jamming devices can be purchased illegally on Craigslist, the black market, or built at home
Jamming devices are illegal under federal law. The Federal Communications Commission (FCC) prohibits the operation, marketing, or sale of any jamming equipment that interferes with authorised radio communications, including cellular and Personal Communication Services (PCS), police radar, and Global Positioning Systems (GPS).
Despite their illegal status, jamming devices can be purchased on the black market, including on sites like Craigslist or through word of mouth. Websites such as PerfectJammer.com and TheSignalJammer.com offer signal jammers for sale, including those that can block cell phone signals, GSM, CDMA, 3G, 4G, 5G, Wi-Fi, and radio frequencies. These websites also offer drone jammers and IED jammers, which can be used to prevent the detonation of explosive devices.
In addition to purchasing jamming devices illegally, it is also possible to build them at home. This can be done by using a standard signal blocker to transmit "white noise" through the same radio frequencies as the target device, disrupting the communication between the base station and the handset. This results in the target device believing there is no service available, effectively creating a "dead zone".
The illegal acquisition and use of jamming devices pose a significant threat to public safety. By interfering with radio transmissions, individuals can delay emergency response times, keeping victims in harm's way longer than necessary. As a result, law enforcement officials are taking steps to address this issue, including filing complaints through the FCC Enforcement Bureau's Public Safety Interference (PSIX-ESIX) Portal.

Jamming is a growing threat to public safety communications, including emergency responders
Jamming is a growing threat to public safety communications and emergency responders. It involves the use of devices that block, jam, or interfere with authorized radio communications, including cellular and Personal Communication Services (PCS), police radar, Global Positioning Systems (GPS), and wireless networking services (Wi-Fi). These jamming devices are illegal under federal law, which prohibits their operation, marketing, and sale. Despite their illegality, they are sometimes used to disrupt emergency response communications, posing a significant danger to public safety.
The use of jamming devices can have severe consequences. When responding to an emergency, radio communication between responders and dispatch is crucial. Even a few minutes of disrupted communication can delay emergency responders and keep victims in harm's way longer than necessary. For example, a fire fighter or emergency medical technician may be prevented from using their radio to communicate with their team.
To address this growing threat, the Department of Homeland Security (DHS) Science and Technology Directorate (S&T) has been working to combat jamming. They evaluate the threat, develop and test mitigation technologies and tactics, and work with public safety agencies to update training procedures. DHS S&T also raises awareness of jamming threats and reporting channels through exercises like JamX, which help responders identify, locate, and mitigate the impact of jamming. These exercises involve federal, state, local, and industry participants, including first responders and law enforcement officers.
It is essential to educate operational employees and new hires about jamming threats, symptoms, and response protocols. Agencies should also update their policies and interference reporting requirements and ensure they have the necessary equipment to detect and locate interference. Developing a Primary, Alternate, Contingency, and Emergency (PACE) Plan for communications is crucial, so all operators understand the fallback communication methods in case of jamming. By implementing these measures, public safety agencies can enhance their resilience to jamming threats and ensure effective emergency response despite any communication disruptions.
