How IEEE 802.15.4ab UWB Sensing Is Driving the Next Wave of Automotive Innovation

Ultra-Wideband (UWB) is moving beyond digital keys to become a versatile foundation for automotive sensing, secure ranging, and data communications. With IEEE 802.15.4ab introducing standardized, coordinated multi-anchor sensing, automotive manufacturers can expand UWB applications while improving coverage, reducing blind spots, and addressing interoperability challenges.

This whitepaper from ABI Research explores how next-generation UWB technology is enabling new automotive capabilities, from child presence detection and gesture control to advanced parking assistance. It also examines how Calterah's One UWB Platform enables automotive OEMs to reuse existing hardware across multiple applications, reduce system complexity, and support future vehicle features through software updates.
