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.”
DECADES-OLD ULTRA-WIDEBAND TECHNOLOGY IS ENJOYING A RENAISSANCE IN SECURE ACCESS AND BEYOND
Like Bluetooth and Wi-Fi, ultra-wideband (UWB) is a wireless technology that uses radio waves for communications. By operating at a very high frequency and using a wide spectrum, UWB outperforms other wireless technologies in terms of accuracy, robustness in wireless connectivity, and security.

UWB Use Cases

Have you ever dreamed of having your front door automatically unlock as you approach? Or wished your house would anticipate your needs and set-up the lights and your TV as you sit on your sofa? Or maybe you want to precisely locate critical health monitoring equipment as you join your shift at the hospital. We are excited to let you know that UWB’s unique fine-ranging capabilities are making these previously impossible applications a reality!

Compelling new experiences benefiting users, combined with the development of an open and interoperable ecosystem, is driving rapid and widespread adoption of UWB across multiple markets and applications.

The (r)evolution has started and UWB will soon be at the heart of our daily lives!
