This is used in hands-free digital car keys that unlock a vehicle on approach, for example.<\/p>\n<p>Enhancements enabled by multi-millisecond ranging (MMS) and narrowband assistance (NBA) extend operating range, strengthen connections with devices, it says. Whether carried in bags or rear pockets, for example. And it enables direction finding at close range to better interpret user intent.<\/p>\n<p>The 4ab update also enhances radar mode, improving use cases such as child presence detection (CPD) in vehicles. This is a potentially life-saving feature recommended by Euro-NCAP, the independent vehicle safety assessment organization.<\/p>\n<p>\u201cIEEE 802.15.4ab is the foundation for enabling a new generation of key fobs as part of a digital key system,\u201d said Daniel Siekmann, Head of Car Access HW D&amp;D Team, Forvia Hella.<\/p>\n<p>\u201cIt offers more than eight times the range of 802.15.4z and significantly better non-line-of-sight performance, which allows for key fob functionality to reliably perform from a back-pocket or inside a bag. With backward compatibility to 802.15.4z, it provides a practical path to replace legacy HF\/LF key fobs with a modern ultra-wideband based architecture, a transition that is further enabled by STMicroelectronics\u2019 new ST64UWB chips.\u201d<\/p>\n<p><em>Image: STMicroelectronics<\/em><\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The ST64UWB family from STMicroelectronics supports both the IEEE 802.15.4z and the upcoming .4ab ultra-wideband standard with multi-millisecond ranging (MMS) including narrow-band assistance radio (NBA).
