• New IoT ICs deliver highly precise positioning capabilities and fine ranging for IoT applications such as smart locks and IoT sensors
• UWB IoT modules and development kits are available now through NXP’s partner network
• Introducing TrimensionTM under the new brand name NXP offers one of the broadest UWB portfolios available with tailored sensing solutions for vehicles, smartphones, and IoT devices
Indoor positioning is, in many ways, an inside version of the satellite-navigation apps we rely on for outdoor navigation, but with an added twist – it can also be used to help locate people and things.
In this paper we present an overview on the development and standardization of ultra-wideband systems, technical aspects of the IEEE 802.15.4 standard, and improvements made by the 802.15.4z amendment. We also explain the basic workings of a physical access system, the desired seamless access experience and how ultra-wideband technology can enable it. In addition, we briefly compare ultra-wideband to facial recognition access systems. We conclude by mentioning how ultra-wideband technology may extend to other related applications.
Ultra-Wideband (UWB) technology has the unique ability to deliver unprecedented accuracy and security when measuring the distance to a target or determining position, transforming the way people experience connectivity. Computerworld recently said that “One way to think of it is as a radar that can continuously scan an entire room and precisely lock on to an object like a laser beam to discover its location and communicate data.”
