NI is working with the wireless research centre within New York University Tandon School of Engineering to fund the development of mmWave communications, channel measurement and channel emulation research for 5G communications. NI has donated almost $1m (£806,000) to the NYU’s wireless group. This will include equipping labs with software defined radio hardware and software. Millimetre-wave (mmWave) frequencies have now ...

Georgia Tech researchers have created a non-linear optical metamaterial that produces a spectral shift under only milliwatts of radation, suspecting it to have the strongest non-linear optical rotation ever reported for a chiral metamaterial – about a hundred thousand times larger than the current record measurement for this type of structure, said the university. A 500μW to 15mW change in ...

“Showcasing key enabling 5G technologies for a proof-of-concept environment at the 2018 Winter Olympics in PyeongChang, Korea."

Qualcomm Technologies has selected a RF test system from Rohde & Schwarz to test and characterise its first generation 5G RF transceiver (SDR051). Qualcomm announced its Snapdragon X50 5G modem platform in October 2016. It is designed to support download speeds of up to 5Gbit/s, initially using very wide bandwidths available in the 28GHz millimetre wave (mmWave) band. Sampling of ...

Guildford-based Lime Microsystems is to seek crowd funding to take software-defined radio (SDR) small cell and carrier-class base-stations to market. The campaign, dubbed LimeNET, will launch on 27th April on Crowd Supply. The products it intends to create are: LimeNET Mini (pictured), an app-enabled, small cell base station aimed at residential SDR applications such as IoT. LimeNET, a more-powerful version for carrier-class ...

National Instruments says it has given the world’s first public demonstration of a real-time, over-the-air prototype for Verizon 5G specification operating in the 28GHz frequency band which is likely to be deployed for first 5G services in the US. A prototype system was built using NI’s mmWave transceiver system with a new version of the RF mmWave heads operating at 28GHz and phased array antennas developed ...

Collaborative research taking place between the Universities of Bristol and Lund, National Instruments and BT has set up field trials of a massive MIMO system working in a large indoor environment. The aim was to test massive MIMO spatial multiplexing indoors and improve the understanding of massive MIMO radio channels under mobile conditions with untethered devices. As a result of ...

French lab Leti has modelled indoor V and E Band millimeter-wave propagation to identify space for 5G comms. Classic frequency bands for mobile communication below 6GHz cannot meet throughput requirements projected for future needs due to network congestion and limited bandwidth. However, the majority of demand could be met using millimeter-wave (mm-wave) spectrum – with potential for multi-Gbit/s A key ...

NXP and Canonical have ported Ubuntu Core to NXP's quad ARM Cortex-A53 core LS1043A SoC, aimed at IoT gateways and networking equipment.

AMS has come up with a new communications interface for audio devices that uses the microphone wire in a standard 3.5mm audio cable to carry power and bidirectional data with a rate of up to 16Mbit/s, as well as digital audio signals. According to AMS, this can eliminate the need for a battery in noise-cancelling 3.5mm headsets. Called Accessory Communications ...
