SPARK Microsystems SR1120 UWB ultra-low-power transceiver delivers up to 41 Mbps throughput

SPARK Microsystems SR1120 is the company’s second-generation ultra-wideband (UWB) wireless transceiver capable of up to 41 Mbps throughput at ultra-low power and up to 100 times lower power ranging than UWB competitors. The Canadian company also highlights the outperformance of their UWB solution over Bluetooth with the new SR1120 offering 40 times higher data rates than Bluetooth chips, while consuming 25 times less power than Bluetooth and offering 60 times lower latency. However, readers should note that Bluetooth LE is supposed to support up to 2 Mbps, so it should (only) be up to about 20 times faster, and Bluetooth HDT is coming soon with data rates of up to 7.5 Mbps to further narrow the gap. SPARK SR1120 key features and specifications: Compliant with the upcoming IEEE 802.15.4ab low-energy UWB PHY standard Dynamically reconfigurable UWB spectrum 6.2–9.5 GHz band Up to 3 dBm TX power RX sensitivity of -81 […]

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 […]

NOVELDA’s latest UWB radar presence sensor consumes less than 100 µW

NOVELDA has unveiled a new low-power ultra-wideband (UWB) radar presence sensor with a power consumption of under 100 µW and designed to operate on two AAA batteries for up to four years. We first wrote about NOVELDA in 2021 where we covered their UWB X4 presence sensor capable of detecting submillimeter movements with a power consumption of under 2mW. The company has further optimized the technology and has come up with a 30x5mm module capable of doing the same with 0.1mW power consumption. The sensor is said to work behind various materials such as plastics, tempered glass, and ceramics, the detection zone size and shape can be adjusted to meet the application requirements, and the device provides accurate angle and distance information. The new ultra-low power UWB radar presence sensor will mostly be useful for energy/resource savings, lengthening a product’s life cycle, and health monitoring with some of the potential […]
