Keysight Technologies and Credo Semiconductor have demonstrated IEEE P802.3dj draft specification compliant 1.6Tbit/s Ethernet measurements for full line rate Layer 2 Ethernet traffic in hardware. “This provides proof that 1.6T Ethernet speed is possible, and that its performance can be measured,” according to Keysight. The rig transmits and processes more than a billion packets per second over a two meter electrical ...

As accelerated computing reaches its tipping point, Nvidia’s CEO explained the company’s plan is not to drive down costs but to scale up performance. He was speaking at Nvidia GTC in San Jose, introducing the Blackwell AI superchip. It will democratise trillion parameter AI, promises Huang, to meet the 1.8 trillion parameters computing performance of accelerated computing. In the home ...

U-blox is sampling a module that combine LTE-M cellular communication (23dBm output) and GNSS for precise location finding. SARA-R520M10 is the super-set device, combining on-board an LTE-M and NB-IoT IC (v2 of UBX-R5) with the company’s M10 GNSS receiver IC, allowing concurrent communication and location-finding in a 16 x 26 x 2.2mm package. Cellular coverage is global, and the module ...

Parallel Wireless (PW), the US  O-RAN specialist has deployed 1,500 O-RAN  sites across Africa. Expanding mobile connectivity throughout Africa is a unique challenge due to unreliable or inaccessible sources of electricity and challenging landscapes that make physical access difficult. PW partnered with regional telecommunications providers and governments in countries including Nigeria, Tanzania, Guinea Conakry, Ghana, South Sudan, Uganda, DRC, and ...

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 ...

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 ...

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 ...
