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.…

Developers can now implement Ultra-Wideband (UWB) support in their apps with Android Jetpack after it was only available for system apps.

The tech will make features like AirDrop more powerful and can help you find lost items or easily manage nearby appliances using just your smartphone.

Apple has announced a new 'Nearby Interaction' framework, that will allow developers to take advantage of the iPhone's U1 chip in iOS 14.

Opening the Find My feature to other companies was seen as an olive branch to developers. But Apple threatened legal action if developers talked about the software.

Tile is preparing to introduce a new product this year that will serve as a rival to Apple’s long-awaited AirTags and other lost-item trackers coming to the market, including those from Samsung, TechCrunch has learned. While previous Tile trackers have leveraged Bluetooth to help users locate lost items — like a misplaced set of keys, […]

Imagine a world where you never have to worry about your assets running out of power. UWB asset tracking can make this dream a reality! Self-powered, batteryless technology will be the key for widespread use of UWB - spanning a wide range of IoT devices - tags, product packaging, labels. In this article, we will discuss how UWB technology can be used to track assets without the need for a battery.

Ultra-wideband (UWB) radars are sensors allowing to track people in critical environments and situations. The results reached by single UWB sensors for such applications have shown that they are able to detect and track a person very well in a single person scenario. However, in multiple moving person scenarios, the ability of a single UWB sensor to detect several persons is usually significantly reduced. This is caused by a mutual shielding among people. In this paper, we will deal with the mutual shielding effect and its impacts, as well as with the methods of improving multiple moving person tracking by UWB radars. Firstly, we will provide a comprehensive description of the mutual shielding effect. Then, based on its analyses, we will state three complementary approaches created by the authors of this paper to reduce its impacts. They include an enhancement of the low-level echo of the targets, radar antenna array positioning at a convenient height, UWB sensor network application and, finally, their mutual combinations. The properties of those approaches will be demonstrated by two experimental measurements aimed at through wall tracking of two and three people, respectively. The results obtained in the experiments will illustrate the mutual shielding effect and the potential of the methods we have proposed to reduce its impacts.

The safety aspects of people exposed to the field emitted by ultra wideband (UWB) radar, operating both in the spatial environment and on ground, for breath activity monitoring are analyzed. The basic restrictions and reference levels reported in the ICNIRP safety guideline are considered, and the compliance of electromagnetic fields radiated by a UWB radar with these limits is evaluated. First, simplified analytical approaches are used; then, both a 3-dimensional multilayered body model and an anatomical model of the head have been used to better evaluate the electromagnetic absorption when a UWB antenna is placed in front of the head. The obtained results show that if the field emitted by the UWB radar is compliant with spatial and/or ground emission masks, then both reference levels and basic restrictions are largely satisfied.

Remarkable progress has been achieved in the detection of single stationary human. However, restricted by the mutual interference of multiple humans (e.g., strong sidelobes of the torsos and the shadow effect), detection and localization of the multiple stationary humans remains a huge challenge.
