Zhejiang University and Microaiot have created a passive crystal-less tag IC that both receives its instructions and is powered by Wi-Fi, and sends its responses over Bluetooth. They described the device at ISSCC in San Francisco this week. The tag has two antennas, with both used to extract power from the incident Wi-Fi field. One also receives the Wi-Fi (802.11b) ...

Anritsu has cut down its ME7873NR 5G New Radio RF conformance test system to create a bench-top ‘Lite’ model (right) supporting 5G sub-6GHz (FR1) TRx test cases. “ME7873NR Lite is an all-in-one tester,” said the company. “In comparison to the predecessor rack models, the lite model has stronger test performance at a reasonable price as a result of cutting the ...

Tokyo Institute of Technology has created a Sub-THz 6G transceiver, which will be revealed next week at the VLSI Symposium. Capable of transmission and reception at over 100GHz, and at 112Gbit/s, “by effectively suppressing the self-interference caused by the transmission signal leaking into the receiver, the proposed architecture reaches unprecedented data rates while maintaining a surprisingly compact size”, according to ...

With Matter communication in mind, Murata has combined Wi-Fi 6, Bluetooth and IEEE 802.15.4 LR-WPAN radios in a single module – LBES5PL2EL, which it described in detail at Embedded World in Nuremberg today. “There are still only a few Matter-compliant solutions on the market, yet the potential for it to deliver convenience and comfort to the places in which we ...

The Square Kilometre Array radio telescope got its next official launch this week, when director-general Philip Diamond travelled to the site where SKA-Low (below) will be built in Western Australia and council chair Catherine Cesarsky went to the SKA-Mid (right) site in South Africa’s Northern Cape. “The SKA project has been many years in the making,” said Cesarsky. “Today, we ...

The person behind the excellent and very professional Signal Path YouTube channel has taken apart a 60GHz WiGig terminal and then x-rayed the tiny phased array antennas inside. That’s right, he has access to a high-resolution x-ray machine. I have to be honest here and admit that at first thought they were badly-wired passive phased arrays until I realised that ...

U-blox has announced a radio module supporting Wi-Fi 6, Bluetooth low energy 5.2 and IEEE 802.15.4 (Thread and Zigbee) that occupies only 10.4 x 14.3 x 1.9mm. “Wi-Fi 6, also referred to as 802.11ax, offers better network efficiency – especially in congested areas, lower latency and improved range over previous Wi-Fi standards,” said U-blox. “Thread paves the way for low-power IP-based mesh ...

Land speed record cars are fascinating things, with technology pushed to its limits. If safety of the driver is of primary concern – as it should be – then few people can afford to play at the highest levels. However, I just came across something that sounds fun, and intellectually challenging, and safe for the driver. And that is radio ...

I think this counts as one for our Gadget in Extremis category: a radio telescope the size of earth. Yes, the one capable of taking pictures of a Black Hole.

Inspired by acoustics, a French-US team has found a way to locate objects in a room simply by their microwave scattering characteristics. Similar to diffusing reverberant acoustic wave spectroscopy (DRAWS), the techniques relies on the room having walls that reflect radio waves – reflecting sufficiently to fill the room with a complex field of interference patterns. An object introduced or ...
