NXP has combined short-range 6 – 8.5GHz UWB radar, secure ranging and angle-of-arrival processing on a single chip. Called SR250, it is for “a world that anticipates and automates, enabling a variety of new user experiences based on location, presence or motion detection across consumer or industrial IoT applications”, claimed the company. It is said to support 3D angle-of-arrival and ...

This year is the time for ultra-wideband to rise and shine, says Jean-Christophe Doucet. Ultra-wideband (UWB) was once considered a niche, but intriguing alternative to incumbent presence detection and tracking technologies, including radio frequency identification, localisation trackers and infrared sensors. Despite its advantages, the industry overlooked UWB until recently. Experts now project that UWB implementation will grow significantly. They estimate ...

NXP has introduced an intelligent automotive RF IC that can implement automatic vehicle unlocking and short-range in-cabin radar, for example. “This enables OEMs to transform a single UWB-based car access system into a flexible, multi-purpose platform, enabling multiple use cases with the same hardware – for example, OEMs can leverage their secure car access system to also deliver features like ...

Infineon has bought the Zurich-based UWB startup 3db Access (3db). 3db delivers secured, ultra-low power and high-precision integrated UWB ranging and sensing products which enable a broad range of applications including provable secured access to valuable assets (vehicles, buildings), secured proof of proximity for seamless mobile payments and real-time high accuracy and precision localisation of connected, intelligent devices. Infineon now ...

Belgian lab Imec is claiming record ranging precision and power consumption for a novel 6 – 9GHz IEEE 802.15.4z UWB (ultra-wide-band) impulse-radio transceiver: 1.4mm ranging, and 8.7mW Tx plus 21mW Rx consumption in continuous mode. “It paves the way for a variety of automotive applications,” according to Imec. “One use-case includes the creation of radar-on-chip systems for in-cabin child presence ...

Renesas has teamed up with consultancy Altran to develop a social distancing wearable platform based on ultra-wideband (UWB) radio technology – earlier this year Renesas licensed UWB technology from fabless chip firm 3db Access. Physically, it is a band worn like a wristwatch, combining Renesas’ S128 MCU with secure ranging based on 3db Access’ 3DB6830 UWB chip. It is a message-and-reply system, ...

The ASSA ABLOY Group which includes HID Global, and NXP Semiconductors, Samsung Electronics, and Bosch have launched the FiRa Consortium. The new coalition is designed to grow the Ultra-Wideband (UWB) ecosystem so new use cases for fine ranging capabilities can thrive, ultimately setting a new standard in seamless user experiences. Sony Imaging Products & Solutions Inc., LitePoint and the Telecommunications ...

Ultra-wide-band (UWB) pulsed radar is the key to scanning sewer pipes quickly, claim researchers from Louisiana Tech University.

UWB rides again with an interesting application in time-of-flight measurement enabled by the Sofia-Antipolis RF packaging specialist, Insight-SIP, which is celebrating its 10th birthday today with a party for 100 people in the South of France. UWB is a relatively new departure for Insight-SIP which has based most of its product portfolio on Bluetooth LE using a Nordic Semiconductor chip-set. ...

Over the last month or so, the discussion around Ultra Wideband (UWB) has been about recent developments in the companies developing the technology. WiQuest, an early leader in the UWB space, announced at the end of October that it was unable to raise a new round of funding and had to shut its doors. On the heels of that news ...
