Tesla FCC filings suggest ultra-wideband support for seamless, ultra-secure vehicle access

Documents filed with the Federal Communications Commission have hinted that Tesla may consider using ultra-wideband (UWB) technology for its vehicles, being one of the first automakers to do so. UWB, a technology developed by tech giants like Apple and Samsung, would allow car owners to unlock their vehicles without taking their mobile device out of their pocket.

Tesla submitted six new products for FCC review on September 9. These products included two key fobs, a security controller and a number of “end points” that would be installed inside the chassis and cab of a vehicle. At least some of these products have been specifically listed to support UWB communication.

There are several notable aspects in Tesla’s FCC filings. Tesla included a full operational description of the technology, which revealed its intention to adopt a standardized implementation of ultra-wideband technology. This, to a point, suggests that UWB technology from devices like Apple and Samsung smartphones should be compatible, at least in theory. The technology is also designed to let users know how far their vehicle is.

As stated in a report by The edge, this “range” would be the key to avoiding replay attacks, which could make a Tesla believe its keychain is closer than it actually is. This is a point of attack that has been exploited by security researchers in the past, some of whom were able to gain access to a Tesla by spoofing the vehicle’s key fob system. Tesla’s security features like PIN to Drive were a response to these attacks. UWB may also support other uses, such as locating a vehicle in a crowded parking lot.

Granted, Tesla’s FCC filings do not guarantee that ultra-broadband technology is actually coming to its vehicles. However, it should be noted that FCC documents are generally a good sign that a company is serious enough in deploying new technology, with depots sometimes becoming one of the last tipping points for a product before it is released. ‘reaches the market.
