The DALI Alliance has specified wireless-to-DALI gateways to link existing DALI wired products with Bluetooth mesh or Zigbee wireless ecosystems. “Wireless to DALI gateways provide the flexibility to incorporate DALI luminaires and other DALI devices into the control network, so it becomes straightforward to add lighting capabilities alongside the other features of the wireless ecosystem,” according to the Alliance. “Existing ...
For USB Type-C with Power Delivery, Microchip has created a framework allowing designers to add their code to the its Power Delivery software stack. “With our Power Delivery software framework, all Microchip MCUs and standalone controllers that support USB-C now share the same PD code base,” said Microchip v-p Charles Forni. “This code is provided free to customers and is easy ...
Inmarsat has launched civil court proceedings in the Netherlands over 5G spectrum allocation. It is looking to protect its provision of maritime and aviation safety services from its ground station in Borum. The UK satellite operator says it is seeking a judge’s ruling on potential illegality of the country’s proposed National Frequency Plan. Basically, it is seeking an injunction to ...
Cambridge-based flexible electronics company PragmatIC has been awarded a £1.3m by the UK Government Sustainable Innovation Fund for a recycling scheme based on NFC tags. “PragmatIC consider this to be a commercial pilot, with the next step being commercial rollouts with global partners,” company chief commercial officer Alastair Hanlon told Electronics Weekly. In the year-long scheme, called Sprite (sustainable plastics recycling ...
ETSI’s international emergency communications interoperability plugfest revealed that 87% of 285 test pairings were interoperable. The remote event was a cooperation between ETSI, EENA (European emergency number association) and NENA (9-1-1 association) – this was the first time the European event partnered with NENA’s US ICE 9 event. “Crossing borders and oceans, the event helped to ensure efficient, interoperable emergency communications for ...
In a silicon-compatible parallel to fibre optics, MIT is using polymer-based ribbon waveguides to carry data between chips at 105Gbit/s – waveguide dimensions and material are chosen so that it propagates electromagnetic radiation between 200 and 335GHz, over 300mm of waveguide. To handle suitable sub-Thz frequencies, transmitter and receiver were made on a 130nm SiGe BiCMOS process using largely bipolar transistors in ...
Osaka University has teamed up with Rohm to send 8K video at 48Gbit/s over a 300GHz carrier using a simple modulation technique. “In general, such ultra-high-speed data transmission experiments are performed using multi-level modulations via a complex system with high power consumption that uses off-line or on-line digital signal processing,” said team leader Masayuki Fujita. “The present real-time demonstration, which ...
Maxim has announced a suite of integrated circuits and reference designs for industrial automation using IO-Link communications. IO-Link is a short-range (<20m) point-to-point industrial bus developed to connect sensors and actuators to a local hub, from which the data is transferred to a remote PLC (programmable logic controller) via Ethernet or other long-range field bus. “The IO-Link interface allows every ...
Xilinx has announced an enhanced Zynq RFSoC architecture to meet the requirements of a second wave of 5G. The ZynqRFSoC DFE integrates hardened digital front end application-specific blocks for 5G NR performance. It will operate up to 7.125GHz and is futureproofed for 3GPP and O-RAN radio architectures, says Gilles Garcia, director of Wired Communication, at Xilinx. Release 17 of 3GPP ...
Amazon has released details of its ‘Sidewalk’ medium-distance wireless network, and its silicon partners including Nordic Semiconductor, Semtech, Silicon Labs and Texas Instruments. In a nutshell, it is a combination and coordination of wireless technologies – LoRa and FSK at 900MHz, and Bluetooth Low Energy at 2.4GHz – and shared networking that will offer low-power wireless devices across a neighbourhood bi-directional ...
