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.

Today the US Patent & Trademark Office published a patent application from Apple that relates to a "Modular Wall Unit System." It's a vastly grander vision for Apple's next-gen Smart Home project – and well beyond a simple mesh network.

Since the iPhone 11 announcement, theories have abounded that Apple’s new U1 wireless chip is actually a Decawave Ultra Wideband DW1000. But it turns out the iPhone’s ultra wideband chip is Apple’s own design, and they have some exciting plans for it.

Imec has developed a impulse-radio UWM transmitter IC measuring 0.155mm², with a power consumption of less than 10 milliwatt (mW), fabbed in 28nm CMOS.

At the recent ISSCC conference, imec presented a fast and low-power UWB transmitter chip and a low-power flexible MPU.

Some embodiments include a system, method, and computer program product for managing the Ultra Wideband (UWB) systems, especially when the UWB system is collocated with another wireless system (e.g., WiFi) to transmit and/or receive UWB signals with an occupied bandwidth (OBW) that satisfies a UWB OBW standard (e.g., a UWB OBW>=500 MHz.) In some embodiments a TailBit signal (e.g., a periodic signal at a selected frequency) is added to a UWB packet to generate frequency components at the selected frequency that enables the power spectrum of the TailBit UWB signal to satisfy the UWB OBW standard. In some embodiments an altered code sequence is used to generate an altered spread signal, where the altered code sequence reduces or removes a frequency component peak near DC frequency of the power spectrum of an altered UWB signal, resulting in altered UWB OBW that satisfies the UWB OBW standard.

This invention generally relates to ultra wideband (UWB) communication, and in particular to methods and apparatus for enabling such communicationWC 1 through a building, comprising generating a UWB signal and coupling the UWB signal to at least one electrical conductor of a mains power supply circuit of the building to distribute the UWB signal. This facilitates implementation of a UWB network with reduced interference. AlterWC 1native building wiring systems may be employed such as Cat 5 for computer networking or onWC 1e or two conducters of a telephone cable. The coupling may be direct or contactless such as capacitative coupling.
