French laboratory CEA-Leti looking to find ways to improve road safety through automated vehicle-to-vehicle communication. Its initiative is intended to “contribute to a higher level of vehicle automation and cooperation by expanding the latest developments in vehicular wireless communications that improve reaction time, pedestrian detection and overall vehicle performance”, according to Leti. By “combining learnings from participation in three EU ...

Bluetooth Low Energy Audio is finally available in IoT devices. Dr Nick Wood, of Insight SiP, explains why it has taken more than two years from SIG revision to realisation. In early December 2020 the Bluetooth SIG (Special Interest Group) released revision 5.2 of Bluetooth. One of the key upgrades was the addition of BLE Audio (Bluetooth Low Energy Audio). ...

Using a safety channel to counter weaknesses in algorithms could steer the automation of commercial vehicles, proposes Eric Richter of BaseLabs. The safe automation of commercial vehicles is a tremendous request from the market. Business cases appear attractive and technical issues seem solvable, yet still, ensuring the safety of such highly automated vehicles is challenging. Designers have to consider 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 ...

Software designed to detect child abuse images on smartphones, which could be mandated by governments in some counties, can be covertly repurposed to intrude on personal privacy, according to research at Imperial college. ‘Client-side scanning’ (CSS) is an image analysis technique based on ‘perceptual hashing’, and is mooted as a way to get around the legitimate problem of criminals hiding ...

Microchip has created a set of dual-channel single-lane USB 3.2 Gen1 SuperSpeed reclocker redriver ICs for automotive and industrial cables up to 15m long. “Adding electronic components to applications across automotive, industrial and consumer industries has spurred the need for far-reaching USB cabling products,” according to the company. EQCO510 is the automotive version, qualified to AEC-Q100 Grade 2 and operates ...

Route planning has started on the pan-Arctic submarine cable that could link Europe, North America and Asia via the Northwest Passage – the latter opening as formerly permanent ice yields to climate change. The idea of the project, dubbed Far North Fiber, is to terminate in Japan, Norway and Ireland, and have branches to Alaska, Canada and Greenland (see map). ...

MediaTek has announced some details of its Dimensity 7200 phone SoC. To be built on a 4nm process from TSMC, it will have eight Arm cores: two 2.8GHz Cortex-A715 cores and six Cortex-A510, then MediaTek’s own AI processing pnit (APU) and an Arm Mali G610 GPU. Memory runs at 6.4Gbit/s and there is UFS 3.1 for storage. For gamers, there ...

BT and Stratospheric Platforms are to test phased array antennas designed to provide 4G and 5G coverage from stratospheric aircraft into the wilds. “This partnership will build on SPL’s world-first 5G demonstration from the stratosphere in 2022,” said SPL CEO Richard Deakin. Funded by Innovate UK, the trials will be at BT’s labs at Adastral Park and “could offer transformational ...

To defend against quantum computer based hacking, Infineon and partners have revealed an electronic passport demonstrator that meets the security requirements of the quantum computing era, claims Infineon. “Today we are launching the encryption procedures which will be needed to repel quantum computer attacks of tomorrow,” said company head of identification products Maurizio Skerlj. “Working together with our collaboration partners ...
