The iCIRRUS project concerns an intelligent cloud-Radio Access Network for 5G

Anritsu has announced that the LTE-Advanced RF Conformance Test System ME7873LA has obtained PTCRB certification for RF Conformance Tests of 5 Downlink Carrier Aggregation (5DL CA) forming a key LTE-Advanced technology. With 5 Downlink Carrier Aggregation (5DL CA) when used with MIMO downlink throughput speeds of 1Gbit/s will be possible as 5G enters commercial service in North America and Japan ...

The MIPI Alliance, the mobile interface specification body, has released a common data format for transmitting software trace and debug information between a test system and a device, such as a system-on-chip (SoC) or platform.  The MIPI SyS-T specification is publicly available to developers, and an accompanying example implementation library is accessible via GitHub. The aim is to avoid market ...

What is believed to be the world’s first demonstration for cellular vehicle-to-everything (C-V2X) direct communications technology operating across vehicles from different manufacturers took place in Washington DC, USA this week. Using Qualcomm’s C-V2X chipset in Audi and Ford vehicles, demonstrations showed how C-V2X communications can alert nearby vehicles to potential hazards when the driver’s view may be obstructed, such as ...

The improvements of 5G networks are undisputed, but how can the faster downloads and better network connectivity be used? Caroline Hayes looks at some real cases at a Bristol urban network weekend and the recent Winter Olympic Games in PyeongChang. Improved download speeds of 10Gbit/s – a considerable increase from the 150Mbit/s of 4G LTE and 300Mbit/s of 4G LTE-Advanced ...

US energy harvesting firm Powercast has developed a battery-free retail price tag that can be changed from 2m away using a hand-held UHF programmer. Key to the tag is the firm’s PCC110 UHF-to-dc harvestign chip and an Eink display that only needs power to change, retaining its display after power is removed. “Powercast developed the concept tag to free retailers ...

For the first time anywhere in the world this weekend people in Bristol will experience LiFi provided by pureLiFi

Silicon Labs revealed a Wi-Fi transceiver which consumes so little that it can be used in battery powered IoT sensor nodes, for example. Revealed at Embedded World, the WFM200 system-in-package (SiP, 6.5 x 6.5mm LGA52) consumes 200µA (average, delivery traffic indication message (DTIM)= 3). “We’ve delivered the first low-power Wi-Fi portfolio designed specifically for the IoT, enabling secure, battery-powered connected ...

The mobile industry’s decision at the end of 2017 to agree on millimetre-wave frequency bands for 5G has provided the trigger for an acceleration in 5G network development At Mobile World Congress in Barcelona this week, mobile operators said the ratification of the 5G New Radio (NR) standards will mean they can aim for a rollout of commercial 5G services ...
