Tiago Rodrigues provides an update on the long range, low power connectivity standard that he believes is the next big thing for the IoT. Wi-Fi HaLow has been called an IoT enabler that overcomes the challenges faced by wireless low-power IoT devices, but what is it, and why does it matter? Also known as IEEE 802.11ah, Wi-Fi HaLow began life ...

Antenna maker Taoglas has started manufacturing enclosures that include antennas. Called the Thunder series, the enclosures allow a router to be mounted outdoors, right next to the antenna “significantly reducing the need for long RF cables – cutting tens of meters per deployment – minimising signal loss”, according to the company. There are 14 ABS enclosures covering seven routers from ...

Anritsu has teamed up with Microwave Vision to offer a Wi-Fi 7 over-the-air tester. It combines Anritsu’s MT8862A wireless connectivity test set (below) as a signal source with Microwave Vision’s multi-probe over-the-air test system (right) to support IEEE 802.11be measurements – which is the standard behind Wi-Fi 7. “Advanced technologies such as 320MHz channels, 4K QAM and MLO are incorporated ...

Bluetest and Rohde & Schwarz have created a MIMO stress testing perform for IEEE 802.11be  (Wi-Fi 7) equipment. It consists of R&S one-box CMX500 signaling tester (right), a Bluetest RF reverberation chamber – its RTS65, for example (below left), and Bluetest’s Flow control software. “In contrast to anechoic test chambers, reverberation chambers extensively reflect an RF signal inside the chamber, ...

The Qorvo QPF4239 is an integrated front end module (FEM) designed for Wi-Fi 7 (802.11be) systems. The compact form factor and integrated matching minimises layout area in the application. Performance is focused on optimising the PA for a 3.3V supply voltage that conserves power consumption while maintaining the highest linear output power and leading-edge throughput. Integrated die level filtering for ...

Raspberry Pi has announced the Wi-Fi and Bluetooth version of its 21 x 51mm Pico 2 microcontroller board. Called ‘Pico 2 W’, it shares the dual 150MHz Arm Cortex-M33 cores, which can be replaced at boot by dual Hazard3 RISC-V processors. Memory remains 520kbyte of on-chip SRAM plus 4Mbyte of on-board QSPI flash. The added wireless interfaces are 2.4GHz 802.11n ...

Samudrapom Dam looks at the challenges faced by Wi-Fi receivers and the technologies used by newer receiver models to tackle those issues. Wi-Fi/IEEE 802.11 technology is increasingly common as demand rises for faster, more reliable Wi-Fi connections. The technology is constantly evolving to keep pace with rapidly expanding digital services and applications. Wi-Fi receiver challenges One challenge is signal interference ...

STMicroelectronics and Qualcomm have agreed to integrate Qualcomm’s Wi-Fi, Bluetooth and Thread wireless IC, which it describes as ‘AI-powered’, into STM32 development tools. Beyond this, ST said that it plans to introduce self-contained Wi-Fi, Bluetooth and Thread wireless modules that including Qualcomm ICs – with initial products expected to be available to OEMs in the first quarter of next year. “We ...

Blu Wireless, the Bristol mmWave specialist, and railway system integrator Nomad Digital have rolled out superfast wireless connectivity to a key commuter line through Silicon Valley, California, USA. Together, they have implemented Blu Wireless’ mmWave wireless system, LightningBlu for onboard Wi-Fi on Caltrain’s electrified commuter railway service. Blu Wireless’  LightningBlu technology has delivered high connectivity speeds to train passengers right ...

The Qorvo QPF4750 is an extreme wideband medium power front end module (FEM) designed for Wi-Fi 6E (802.11ax) systems. This FEM implements extreme wideband amplfier technology to create an easier to use and extremely compact solution for Wi-Fi applications where operating on any channel within U-NII1-8’s 2GHz of bandwidth is deisred. The small form factor and integrated matching minimizes layout ...
