In August 2013, a New Jersey man was fined $32,000 by the Federal Communications Commission for operating a GPS interceptor. The US Federal Communications Commission (FCC) announced that the man was a driver of a work vehicle, "alleging that he installed and operated a jamming device in a vehicle provided by the company to prevent the GPS system used by the employer from being installed on the vehicle.
Technology news source Gizmodo investigated GPS jammer and found that they were "dangerous, cheap and easy to [obtain and use]". They are also illegal, but this will not prevent people including drivers from using them. GPS scramblers will not only harm your business, but also destroy the emergency frequencies used by 9-1-1, ambulances, fire and police departments. GPS signal jammers even interrupted aircraft navigation.
The use of GPS jamming devices may be more widespread than expected. According to a 2012 study (called the Sentinel project), there are 50 to 450 GPS tracker failures in the UK every day. Fleet drivers and truck drivers are responsible for 90% of such cases. Another study conducted by Rohde & Schwarz in 2014 found that about one-third of trucks on major U.S. highways transmit at the same frequency as GPS-suggesting that these trucks may use GPS signals Jammer.
