U-blox has created an indoor positioning antenna for Bluetooth, designed to be built into end-user products. Bluetooth indoor positioning uses the angle-of-arrival of a signal to at several fixed points in a room. The signal is emitted by the mobile entity to be tracked – a Bluetooth tag, for example. Location is measured to sub-metre accuracy in real-time, according to the ...

Digi-Key Electronics has announced a global distribution partnership with SPARK Microsystems, the ultra wideband specialist, to offer its ultra-low power wireless communications ICs. Described as next-generation ultra-wideband wireless transceivers, the products target personal area networks and IoT-connected devices. For example, the SPARK SR1000 UWB IC family (pictured) support data rates of up to 10 Mbps at 1.5 nJ/bit (energy consumption ...

NXP has combined NFC, secure authentication, anti-tamper and a sensor interface into a single battery-free chip family called NTAG 22x. The parts are aimed high-volume tagging applications, for example: authenticating retail products or protecting them from tampering, or battery-free environment sensing. They include ISO/IEC 14443-A communication and function as an NFC Forum Type 2 tag, and include AES-128 cryptography and CC EAL3+ ...

Silicon Labs has introduced a wireless microcontroller with a hardware AI accelerator that can work with Matter, Zigbee, OpenThread, Bluetooth Low Energy and Bluetooth mesh. It comes along with a software tool kit for machine learning. Called EFR32MG24, “this new hardware and software platform will help bring AI and ML applications and wireless to battery-powered edge devices,” according to the company. ...

U-blox has announced two LTE Cat 1 module series offering multi-regional data coverage. “The modules offer device makers facing imminent 2G and 3G network sunsets a migration path to 4G technology for data streaming applications,” according to the Swiss company. “Additionally they offer MQTT Anywhere and MQTT Flex connectivity via u-blox’s Thingstream platform out of the box, enabling seamless roaming.” ...

Movandi, the 5G mmWave RF specialist, and South Korea’s Doosan Group, have hooked up to design and manufacture smart repeater modules based on Movandi’s BeamXR technology. Together, Movandi and Doosan are delivering BeamXR-powered platforms including O-RAN RU radio units, small cells, mobile devices to global providers of 5G mmWave network repeater equipment including FRTek (Fiber Radio Technologies). Movandi recently announced new, upgraded ...

Siretta is a UK manufacturer and developer specialising in the IoT, with a focus ...

U-blox has announced two modules designed to enable AWS (Amazon web services) cloud services for device and fleet management. “For many businesses, connecting devices to the cloud remains challenging,” according to the company, claiming: “Existing solutions involve installing and maintaining dedicated software to manage connectivity on the devices. In addition, many legacy devices are too resource-constrained to accommodate the additional ...

Onsemi has introduced a Bluetooth wireless microcontroller, which has topped the charts on two of EEMBC’s benchmarks. Dubbed RSL15, it has Arm’s secured Cortex-M33 processor running at 48MHz, plus Bluetooth Low Energy 5.2 wireless. “RSL15 was certified by the Embedded Microprocessor Benchmark Consortium,” said Onsemi. “The ULPMark CoreMark measures the energy efficiency of microcontrollers used in embedded systems while active. RSL15 ...

u-blox is aiming at centimeter-level positioning for industrial navigation and robotics with a pair of GNSS (global navigation satellite system) correction receivers and a corresponding up-grade to its existing ZED-F9P high-precision GNSS receiver module. The correction receivers stream correction data from communication satellites. The “new correction service receivers offer broad geographical coverage across Europe, continental US and Japan,” according to the ...
