Part its ‘IoT Evolve’ programme, CENSIS teamed up with consultancy FarrPoint to monitor humidity, temperature and visitor numbers in the Ravenspoint Centre Museum (right) using a LoRaWAN network – adding to an existing network which covers the museum’s storage facility. Visitor tracking sensors are now mooted for the on-site café. “The system will automate data collection, a task previously performed ...

Nanusens has demonstrated a mems digitally-tuneable capacitor for 5G and 6G RF front-ends, that is compatible with CMOS IC processing and can be integrated with circuitry. The Q-factor is above 100 at 1GHz, and the four-bit capacitor has a minimum capacitance of 450fF (30fF/capacitor) with them all off and tunes up to ~1pF – a capacitance ratio of 2.2 which ...

OMC has launched a fibre optic transceiver shield for Arduino Uno, designed to work with PMMA (polymer) optical cables up to 25m long, plus demonstration software. Operation is possible at 300, 600, 1,200, 2,400, 4,800, 9,600, 14,400, 19,200, 28,800, 38,400, 57,600 or 115,200bit/s. “The actual fibre optic emitter and receiver pair can operate up to 5M baud – the shield ...

Arrow Electronics has developed an ISO 15118 vehicle-to-grid data communication evaluation module. “The software, developed at Arrow’s engineering centre in Gdansk, contains protocol stacks for ISO 15118 V2G. There is also sample application code, as well as support for OCCP [Open Charge-Point Protocol] and Control Pilot interfaces as defined in IEC 61851 and SAE J1772,” said the company. ” V2G ...

A mixer-first sliding-IF architecture has been chosen by a PhD student to create a 300GHz radio receiver front-end using 300GHz Ft (450GHz Fmax) transistors from a 130nm SiGe BiCMOS process. According to the thesis of Sumit Singh, studying at University of Oulu in Finland, down-conversion of the 300GHz carrier is initially by a local oscillator at two-thirds of the carrier, ...

Imec unveiled a CMOS 56Gbit/s zero-IF D-band beam-forming transmitter at the IEEE RFIC Symposium in Washington. “It is a key component of a 4-way beamforming transceiver chip currently being developed by imec’s researchers,” according to the Belgian research lab. “With this technology, they aim to support the deployment of short-range wireless services at frequencies above 100GHz.” It sees Gbit/s communication ...

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 ...
