While gps signal jammer and spoofing are a problem in many areas of transportation and critical infrastructure, it is often most visible in maritime transport. This is because the automatic identification system (AIS) for collision avoidance and traffic management for large ships transmits location data based on GPS inputs.

These transmissions are received by coastal networks and satellite systems. AIS data is often freely available or easily accessible to the public.

Ships in Russian waters being forged into inland airports, ships in Chinese ports reporting they are inland and circling government buildings, and ships in part of the world broadcasting their location thousands of miles away and in the ocean off Northern California circling, are three of the highest provide examples in recent years.

The FCC has no doubt that “these devices pose a serious risk to public safety communications and may prevent you and others from making emergency and emergency calls. wireless jammer can also disrupt law enforcement communications. "

"Jamming devices pose a serious security risk," said a statement on the website of Fr. Michele Ellison, chief of the agency's enforcement bureau. "In the coming weeks and months, we will intensify our efforts by partnering with law enforcement agencies to address those who continue to break the law."

The agency lives in a world where low-power signal jammer could have a range of 30 feet, while more advanced devices could block all transmissions within the size of a soccer field. Obviously, this raises public safety issues.

But what if a steering wheel with a range of just a few centimeters could incorporate a small-scale blocking technique that is not enough to affect surrounding vehicles or even other occupants of the car, but is sufficient to affect the drivers to keep stupid?

What if this technology was flexible enough not to interfere with medical devices such as pacemakers or insulin pumps? Or with streaming music services?
