US FCC Plans Major UWB Rule Update to Support AI Sensing and Advanced Ranging

According to an analysis by Ceva product director Navot Goren in EE Times Taiwan, the US Federal Communications Commission (FCC) has announced plans to comprehensively update ultra-wideband (UWB) regulations established in 2002. The proposal aims to reflect advancements in high-speed transmission, precise positioning, and coexistence with other wireless services, while considering a new UWB device category to support emerging applications such as AI sensing, advanced ranging, and next-generation access control. In practical deployments, the FCC previously granted an exemption allowing Tesla to use UWB for outdoor ground-based wireless charging alignment, overcoming legacy restrictions on outdoor fixed infrastructure. Concurrently, the IEEE 802.15.4ab standard enhances non-line-of-sight ranging performance and radar sensing capabilities. On the silicon integration front, Ceva and LG Electronics have collaborated to combine baseband IP with RF technology supported on TSMC 22nm process nodes. The article also cites ABI Research forecasts projecting UWB device shipments to grow from 597 million units in 2026 to nearly 1.18 billion units by 2030.

Key takeaways

• The US FCC is planning its first comprehensive UWB regulatory update since 2002, exploring new classifications for AI sensing and ranging.
• Tesla received an FCC waiver to utilize UWB for outdoor wireless charging alignment, demonstrating expanding needs for physical positioning.
• The IEEE 802.15.4ab standard enhances non-line-of-sight performance and radar sensing amid 6G spectrum coexistence challenges.
• ABI Research estimates UWB device shipments will rise from 597 million units in 2026 to nearly 1.18 billion units by 2030.
