Enforcement Advisory No. 2012-02
CELL JAMMERS, GPS JAMMERS, and OTHER JAMMING DEVICES
CONSUMER ALERT: Using or Importing Jammers is Illegal
Monetary Penalties Can Exceed $100,000 per violation
In recent days, there have been various press reports about commuters
using cell phone jammers to create a "quiet zone" on buses or trains. We
caution consumers that it is against the law to use a cell or GPS jammer
or any other type of device that blocks, jams or interferes with
authorized communications, as well as to import, advertise, sell, or ship
such a device. The FCC Enforcement Bureau has a zero tolerance policy in
this area and will take aggressive action against violators.
***CONSUMER ALERT***
* Illegal to Operate Jammers in the U.S. Unless you are an authorized
federal government user, you may not operate a jammer in the U.S.,
even on private property. This means that it is illegal to use a
jammer on mass transit (e.g., train, bus) or in a residence, vehicle,
school, theater, restaurant or in any other public or private place.
* Illegal to Import Jammers into the U.S. If you purchase a jammer
online and ship it to the U.S., you have violated federal law. When
you buy jammers from outside the U.S.-used or new -you become the
"importer" of an illegal device. It does not matter whether you
purchased the device from an established business or an individual
selling the jammer in an online auction. Jammers imported from
overseas are also subject to seizure at the border.
* Illegal to Sell or Advertise Jammers Online or in Stores. You may not
sell or advertise jammers to individuals or businesses on online
auction or marketplace sites, in retail stores, or even at your local
flea market. Selling even a single jammer is illegal. You also are
prohibited from shipping a jammer in the U.S.
* Monetary Penalties Can Exceed $100,000 per violation. Violations of
the jamming prohibition can lead to substantial monetary penalties (up
to $112,500 for any single act), seizure of the illegal jammer, and
criminal sanctions including imprisonment.
* If you are aware of the use of a jammer, please contact the FCC at
1-888-CALL-FCC or jammerinfo@fcc.gov.
What are "jammers"? Generally, "jammers"-which include devices 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 interfere with authorized radio communications.
How do jammers work? 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
prevent the targeted device from establishing or maintaining a connection.
Jamming technology generally does not discriminate between desirable and
undesirable communications. 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 receiving correct positioning signals; and
* prevent a first responder from locating you in an emergency.
Why are jammers prohibited? Jammers do not just weed out noisy or annoying
conversations and disable unwanted GPS tracking. Jammers can prevent 9-1-1
and other emergency phone calls from getting through or interfere with
police and other law enforcement communications. For example, the recent
use of a cell phone jammer in an office building disrupted communications
of a nearby Fire Department. When Enforcement Bureau agents investigated
the incident, we found that a CPA who apparently did not want to be
disturbed during the busy tax season was using a small, inexpensive cell
jammer inside his office. But, the jammer was disrupting critical public
safety communications outside his building as well.
In another recent instance, a high school teacher used a jammer in his
classroom. Responding to a complaint, Enforcement Bureau agents tracked
the device to a locked cabinet in the metal shop. Unknown to the teacher,
the jammer was blocking all teachers, students, and staff throughout the
school from making any calls, including emergency calls, and it could have
had tragic consequences.
