NXP Trimension SR250 short-range UWB radar supports secure ranging for Smart Homes and Industrial IoT

NXP Semiconductors has recently introduced Trimension SR250 UWB radar, which NXP is calling the industry’s first single-chip solution that combines on-chip processing with short-range ultra-wideband (UWB) radar and secure UWB ranging. Operating at 6-8.5 GHz, the SR250 supports features like 3D angle-of-arrival (AoA), time difference of arrival (TDOA), and time of flight (ToF) measurements accurate to within ±5 cm. The integrated on-chip radar processing reduces power consumption, which increases efficiency and it can work with AI/ML algorithms on host processors like NXP’s i.MX, RW61x, and MCX families. The SR250 is supported by firmware, middleware, and sample applications, simplifying development and deployment. Applications for this device include smart home automation (e.g., turning devices on/off based on presence), secure access, and safety monitoring, as well as industrial uses such as worker tracking, collision avoidance, and danger zone detection. Trimension SR250 UWB radar specification 3D secure ranging Fully interoperable with IEEE 802.15.4z HRP […]

Teledatics HaloMax Wi-Fi HaLow LGA or M.2 module supports over 1000 clients, have been tested at a 100+km range (Crowdfunding)

Teledatics has launched a crowdfunding campaign for the TD-HALOM HaloMax Wi-Fi HaLow module available in LGA and M.2 form factors for long-range and low-power connectivity, as well as HaLow development boards based on the module and various daughterboards for expansion. The wireless module, powered by Newracom’s NRC7394 SoC, is the product of a collaboration between Newracom and Teledatics. According to Zac Freeman, VP of Marketing & Sales at Newracom, the HaloMax module is “the highest output power Wi-Fi HaLow module available on the market. The Teledatics TD-HALOM module transmits at the highest allowable FCC power output and offers a Maximum Range HaLow solution.” Earlier this year, Teledatics broke the record for the longest distance for a Wi-Fi HaLow connection using the HaloMax wireless module and TE Connectivity Yagi antennas. Two Raspberry Pi 4 Model B units were able to communicate over a distance of 106km between Mount Greylock and Mount […]

Bluetooth 6.0 features accurate two-way ranging using Channel Sounding, latency reduction, improved scanning efficiency, and more

The Bluetooth Special Interest Group (SIG) has just announced the release of the Bluetooth 6.0 Core Specification with features and feature enhancements that include Bluetooth Channel Sounding for two-way ranging between BLE devices, decision-based advertising filtering and monitoring advertisers to improve device scanning efficiency, an enhancement to the Isochronous Adaptation Layer (ISOAL) for lower latency and higher reliability, the LL extended feature set, and a frame space update for throughput optimization. Bluetooth 5.4 was released as a minor update mostly adding electronic shelf label (ESL) support in February 2023, or about 18 months ago, but Bluetooth 6.0 is a major update with the most notable feature being Bluetooth Channel Sounding to enable two-way ranging between two Bluetooth LE devices. It’s not the first time we’ve heard about “Bluetooth Channel Sounding” for distance measurements as it was implemented in WiFi 7/6 and Bluetooth 5.4 chipsets such as Synaptics SYN4382 and Broadcom […]
