Generall y, “jammers” — which are also commonly called signal blockers, GPS jammers, cell phone jammers, text blockers, etc. — are illegal radio frequency transmitters that are designed to block, jam, or otherwise inte rfere with authorized radio communications. 2. How do jammers work? Jamming tech nology generally does not disc riminate between desirable and undesirable communications. A jammer can block all radio communications on any device that operates on radio frequencies within its range ( i.e., within a certain radius of the jammer) by emitting radio frequency waves that preven t the targeted device from establishing or maintaining a connection. For example, jammers can: prevent your cell phone from making or receiving calls, text messages, and emails; prevent your Wi-Fi enabled device from connecting to the Internet; prevent your GPS unit from receivin g correct positioning signals; and Page 2 prevent a first responder from lo cating you in an emergency. Of course, losing a signal does not necessa rily mean that someone nearby is using a jammer. See also , Question 20 - Each Time I Visit a Certain Area, I Get the Message “Call Lost.” 3. What laws prohibit the market ing, sale, and use of jammers? Federal law p rohibits the marketing , sale , or use of a transmitter ( e.g. , a jammer) designed to block, jam, or interfere wi th wireless communications. See Communications Act of 1934, as amended, 47 U.S.C. §§ 301, 302a(b), 333. Section 301 of the Communications Act : “No person shall use or operate any apparatus for the transmission of energy or communications or signals by radio...except under and in accordance with [the Communications] Act and with a license in that behalf granted under the pr ovisions of this Act.” 47 U.S.C. § 301. Section 302(b) of the Communications Act : “No person shall manufacture, import, sell, offer for sale, or ship devices or ho me electronic equipment and systems, or use devices, which fail to comply with regulations promulgated pursuant to this section.” 47 U.S.C. § 302a(b). Section 333 of the Communications Act : “No person shall willfully or maliciously interfere with or cause interference to any radio communications of any station licensed or authorized by or under [the Communications] Act or operated by the United States Government.” 47 U.S.C. § 333. Jammers cannot be marketed or operated in th e United States except in the very limited context of authorized, official use by the federal government. 4. Does the term “marketing” have a specific meaning? Yes. “Market ing” is defined in the FCC rules as the “sale or lease, or offering for sale or lease, including advertising for sale or lease, or importation, shipment, or distribution for the purpose of selling or leasing or offering for sale or lease.” 47 C.F.R. § 2.803(e)(4). 5. Why are cell phone jammers, Wi-Fi jammers, and GPS jammers illegal? Jammers are more than just a nuisance; they pose an unacceptable risk to public safety by potentially preventing the transmission of emergency communications. Cell phone jammers do not distinguish between social or other cell phone conversations and an emergency call to a family member or a 9-1- 1 emergency responder. Similarly, GPS and Wi-Fi jammers maliciously disrupt both routine and critical communications services. Jammers could also block more than just cell phone calls; these devices could disrupt important communications services that operate on adjacent frequencies, or worse, they could disrupt all communications wi thin a broad frequency range. Page 3 6. Some devices claim to block cell phone calls, t ext messages, and emails only inside a car. Are these illegal as well? Any device that jams or disrupts cell phone calls, text messages, or other wireless communications by emitting an interfering radi o frequency signal is illegal and may not be marketed or operated in the United States, except in the very limited context of authorized, official use by the federal government . Please note that it may be difficult to determine from an advertisement how a particul ar device functions. You should contact the FCC’s Enforcement Bureau at email@example.com if you have questions. We emphasize that consumers cannot legally operate any radio transmitting device ( e.g. , a Wi-Fi or Bluetooth transmitter, wireless phone , etc.) that does not have an authorization from the FCC and that is not properly labele d with an FCC identification number. ( See Figure 1 below.) Figure 1: Sample FCC ID labels Jamming devices, however, are ineligible to receive a grant of equipment authorization from the FCC or an FCC ID. (The FCC’s O ffice of Engineering and Technology oversees the authorization of non-jamming equipment th at uses the radio frequency spectrum. More information is available at h ttp://www.fcc.gov/encyclopedia/equipment- authorization.) 7. May I order and import a jammer into the U.S.? No. Consum ers may not order a signal jammer from a foreign retailer and have it shipped into the U.S. The Communications Act prohib its the importation of jamming devices into the U.S. except in limited circumstances that do not apply to consumers. See 47 U.S.C. § 302a(b), (c). Page 4 8. What are the penalties for using a jammer? Can I go to prison? Yes. The unl awful use of a jammer is a criminal offense and can result in various sanctions, including a jail sentence. More specifically, the unlawful marketing , sale, or operation of cell phone, GPS, or other signal jammers in the U.S. can result in: significant fines (we call them “monetary forfeitures”) – up to $16,000 for each violation or each day of a continuing violation , and as high as $112,500 for any single act; government seizure of the illegal equipment; and criminal penalties including imprisonment. See 47 U.S.C. §§ 401, 501, 503, 510; 47 C.F.R. § 1.80(b)(3). The FCC has taken action against various indi viduals and business entities for unlawfully operating and marketing jammers. You can find more information on jammer enforcement at www.fcc.gov/encyclopedia/jammer-enforcement. 9. What should I do if I already own a jammer? Any unautho rized person ( i.e. , anyone other than an author ized federal government user) in possession of a jamming device must imme diately cease operation of the device. You can also voluntarily surrender the device to one of the FCC Enforcement Bureau Field Offices (located across the country), by ca lling the FCC’s Enforcement Bureau at (202) 418-7450 for information about the office nearest you, or by sending an email to firstname.lastname@example.org . 10. Whom should I contact if I have additional questions? For additiona l information regarding enforc ement of the jamming prohibition, visit www.fcc.gov/encyclopedia/jammer-enforcement , or contact Kevin Pittman or Neal McNeil of the FCC’s Enforcement Bureau at (202) 418-1160 or email@example.com . MANUFACTURING AND SALES OF JAMMERS 11. Is it illegal to sell a cell phone jammer, GPS jammer, or other jamming device in the U.S. or its Territories? Yes. The sale, lease, importation, distribution, or marketing of jammers in the U.S. or its Territories is prohibited by federal law. See 47 U.S.C. § 302a(b); 47 C.F.R. § 2.803(a). There is a very narrow exception. In limited circumstances, the sale of signal jammers for use by authorized federal ag encies may be permitted. See 47 U.S.C. § 302a(c); 47 C.F.R. § 2.807(d). Please contact the FCC Enforcement Bureau at firstname.lastname@example.org if you have questions about this limited exception. Page 5 12. I sell and ship jammers all over the world through a site on the Internet. What should I do to comply with U.S. law? Manufacturers and retailers of electronic equipment should take affirmative action to comply with U.S. law: Immediately stop marketing within the United States an y equipment that is designed to block, jam, or otherwise interfere with authorized radio communications. Decline to sell or ship such jamming devices to addresses in the United States or its Territories (except in the very limited co ntext of authorized sales to the federal government). For example, some Internet auction or marketplace websites permit a seller to set up restrictions that automat ically block the sale of any item to countries specified by the seller. Ensure that any jamming devices manufactured in the United States are available solely for export and are not for sale domestically except to the U.S. government. We note that U.S. manufacturers should be aware that jammers may be unlawful in other countries. IMPORTANT NOTE ON DISCLAIMERS: We emphasize that it is insufficient and misleading for manufacturers and retailers to include a disclaimer on their websites or in promotional or advertising materials statin g or implying that U.S. consumers bear sole responsibility for complying wi th the applicable legal obli gations. The manufacturer or retailer is also violating the law both by offeri ng the device for sale to U.S. consumers and completing the sales transaction. Use of disc laimers that purport to place the sole burden on the buyer cannot absolve the manuf acturer or retailer of liability. 13. I sell signal jammers on my website but make certain to notify potential buyers that the jamme rs may only be purchased, leased, or operated in the U.S. by authorized federal agents. Ca n I be prosecuted if an unauthorized purchaser ignores this warning? Even with such a notice, a seller will still be subject to prosecution if it sells a jammer to an unauthorized person in the U.S. Because Internet sales often target a worldwid e audience, some Internet retailers display a disclaimer advising that the purchaser bear s sole responsibility for ensuring that the purchase or importation complies with the app licable laws. Although a prominent notice on a webpage warning that the device may not be purchased, leased, or operated in the U.S. would be helpful to consumers, no such notification or disclaimer of responsibility will relieve a seller of its individual liab ility if an unauthorized sale is made. 14. Can I legally manufacture a jammer in the U.S.? Possibly. Ma nufacturers should ensure that any jamming devices manufactured in the U.S. are available solely for export and are not for sale domestically, except in the limited context of authorized sales to the federal government. See 47 U.S.C. § 302a(c); 47 C.F.R. § 2.807(d). Please contact the FCC Enforcement Bureau at email@example.com if you Page 6 have questions about this limited exception. We note that U.S. manufacturers should be aware that jammers may be unlawful in other countries. USE AND OPERATION OF JAMMERS 15. Can I operate a jammer in the U.S.? No. It is a vi olation of federal law to operate jammers in the United States, except for authorized, official use by the U.S. government. 16. I live outside the continental U.S. – in Puerto Rico, the U.S. Virgin Islands, American Samoa, or G uam. Do the re strictions on operating jammers apply to me? Yes. The Communications Act forbids the use of jamming devices in the U.S. and its Territories. 17. I don’t use my cell jammer in public. Can I use it in my own home, business, or vehicle? No. Jamming devices may not be used regardl ess of whether the device is operated on public or private property. If you own a jammer, do not continue to operate it. You risk substantial fines (of up to $16,000 for each violation or each day of a continuing violation, or up to $112,000 for a single act); seizure of the device by the government; and criminal imprisonment. Signal jammers do not respect property lines, and federal law provides no exception that allows for the private or commercial use of a jammer. 18. I am a local government official and I would like to ensur e compliance with laws that prohibit cell phone use at certain times or in certain places. May a cell phone jammer be used in this context? No. The Communications Act does not exempt state or local government officials from the prohibition on jammers. Similarly, state and local school systems are also prohibited from using cell phone jammers. Use of cell pho ne jammers poses an unacceptable risk to public safety. Jammers cannot be marketed or operated in the United States, except in the very limited context of authorized, official use by the federal government. See 47 U.S.C. § 302a(c); 47 C.F.R. § 2.807(d). 19. I am a principal or school teacher and would li ke to use a jammer to limit cell phone calls and texting during school hours. May I do so? No. It is a violation of federal law to operate a jamming device within the U.S. Cell phone jammers do not distinguish between social or other cell phone conversations and an Page 7 emergency call to a family member or a 9-1-1 emergency responder. In an emergency, use of a cell jammer can pose a threat to both students and staff by preventing communications with polic e or emergency services . In other words, jammers, even if carefully ta rgeted, create risks of interference outside their intended zone of operations and can thereby disrupt critical communications by public safety providers, as well as th e legitimate communications of passersby. COMPLAINTS ABOUT JAMMERS 20. Each time I visit a certain area, I get the message “Call Lost” or I can’t make or receive calls on my cell phone. I suspect that someone is using a cell phone jammer, but how can I tell for sure? Losing a signal does not necessarily mean that someone nearby is using a cell phone jammer. In fact, signal loss can be caused by many factors, such as signal blockage by buildings or natural obstructions, unusually he avy call volume in the area, being too far from a cell tower, or being outside of a serv ice provider’s coverage or roaming area. Cell phone users are encouraged to contact their se rvice provider to ensure that coverage is available. If there are no se rvice disruptions and there is interference to authorized communications, the FCC’s Enforcement Bu reau may use specialized equipment to identify the specific location of a jammer. 21. Can I help stop jammers? Yes. You can notify the Enforcement Bureau about the illegal sale or use of jam ming devices by filing a complaint. Sale of Illegal Jamming Devices: You may come across several jamming devices advertised on the Internet. If you ha ve reason to suspect that a company sells jammers in the U.S. and does not restri ct such sales to authorized federal government users , you should contact the FCC’s Enforcement Bureau through the online complaint portal, www.fcc.gov/complaints . Additionally, some online auctions or websit es allow you to notify them of the sale of products that are illegal or that otherwise violate their terms of service by clicking on a “flag” or “report abuse” link. Use of Illegal Jamming Devices: If you have information regarding the use of a jammer in the U.S., you should contact the FCC’s Enforcement Bureau through the FCC’s online complaint portal, www.fcc.gov/complaints . See also , Question 22 - How do I file a jamming complaint? Page 8 Page 9 22. How do I file a jamming complaint with the FCC’s Enforcement Bureau? To file a com plaint alerting the FCC’s Enfo rcement Bureau to illegal cell, GPS, or other jamming devices, please visit www.fcc.gov/complaints , or call 1-888-CALL-FCC (1-888- 225-5322) voice or 1-888-TELL- FCC (1-888-835-5322) TTY. Sale of Illegal Jamming Devices: If your complaint is about the sale of illegal jamming devices, please provide the following information in your complaint: the website address and retailer name; the name and product number of th e jammers that were advertised; the date you viewed the advertisement; and any additional information that yo u believe could be relevant. Use of Illegal Jamming Devices: If your complaint is about the use of illegal jamming devices, please include the following information in your complaint: the time(s) of the occurrence; the date(s) of the occurrence; the location of the occurrence; the name of the person or co mpany operating the jammer; the facts and circumstances that support your belief that a jammer was being used (in addition to loss of signal or poor reception); and any additional information that yo u believe could be relevant. 23. I’d like to file a complaint, but have a question about the jamming prohibition.
