rode-shutterstock_1888235593-300x200.jpg

The next edition of the 3GPP 5G Advanced standard (Release 19) is expected to bring ambient IoT within 6G to increase connectivity from billions of devices to trillions. Voting in December, the telecom companies and mobile operators that make up 3GPP membership will define what is to be in the latest standard. “Ambient IoT will almost certainly be part of ...

Tethered drone covers 28km2 for private 4G LTE, and more for P25 radio

Simoco P25 radio on Vocus mobile network drone

A tethered drone has been used to demonstrate a pop-up large area private 4G LTE cellular network. “This allows the drone to act as a mobile tower in the skies, granting connectivity across expansive areas, covering up to 28km2 for 4G and even further for P25,” according to Simoco Wireless Solutions, which provided P25 radio equipment for the proof-of-concept. “Imagine ...

Can inter-vehicle communication improve road safety, and help drones cooperate?

CEA Leti V2X cooperation

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 ...

BLE Audio and its place in the evolution of Bluetooth

wireless-in-1-300x200.jpg

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). ...

Automotive software

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 ...

VLSI Symposium: 100GHz transceiver for 6G comms

TiTech VLSI2023 6G 100GHz transceiver

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 to scan phones for abuse images is itself open to abuse

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 ...

Reclocker redriver IC for USB 3.2 over 15m cables

Microchip EQCO5X31 cable extender app

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 ...

Japan-USA-Europe fibre link takes the Northwest Passage

Far North Fiber map

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). ...

Phone processor for gaming and AI photography

MediaTek Dimensity_7200

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 ...
