Tesla may be one of the first automakers to use Ultra-Wideband (UWB) technology in their vehicles. According to documents filed with the Federal Communications Commission, the manufacturer has submitted new products that support UWB.
Ultra-Wideband is a radio technology that can use a very low energy level for short-range, high-bandwidth communications over a large portion of the radio spectrum. UWB has traditional applications in non-cooperative radar imaging. Most recent applications target sensor data collection, precision locating, and tracking applications. UWB support has started to appear in high-end smartphones.
In September, Tesla submitted six new “products” for the FCC’s consideration, including two key fobs, a security controller, and a number of “endpoints” that would be installed inside the frame and cabin of a vehicle, according to The Verge. According to FCC filings, at least three of these products clearly support UWB communications.
Tesla's filing with the FCC includes a full description of how the technology works, according to which the latest smartphones could theoretically be compatible. According to the description, a key fob can allow owners to unlock their vehicle without taking it out of their pockets.
As of now, there is no evidence that Tesla will necessarily add UWB to its cars, but filings with the FCC are usually a sign that the company intends to implement the technology. Filing with the FCC is usually one of the last steps before a product goes to market. This is only required if the manufacturer intends to import, sell, or conduct extensive testing of radio products in the United States.
