Cypress is claiming better audio from all-wireless earbuds – headsets without a wire between the transducers. According to the firm, which is sadly not naming names or numbers, the solution features a link budget that is 6dB better than competetors, resulting in up to twice the range – with the extended range improving cross-body performance for uninterrupted earbud audio from ...

Leti and semiconductor IP supplier VSORA demonstrate 5G New Radio Release 15 on a new DSP architecture

MEMS timing specialist SiTime and Intel are to work together on integrating timing for Intel’s 5G multi-mode radio modems, Intel’s 4G chips, and its  millimeter-wave wireless, Wi-Fi, Bluetooth, and GNSS products. SiTime’s MEMS timing solutions enhance system performance in the presence of stressors such as vibration, high temperature, and rapid thermal transients. Such stressors can disrupt the timing signal and ...

California-based design firm Aricent is developing 5G networks software frameworks running on the Intel FlexRAN reference architecture. Aricent’s 5G framework will be integrated with the Intel FlexRAN reference architecture, supporting features compliant to 3GPP specifications for non-standalone modes. The firm’s 4G LTE framework based on Cloud-RAN (C-RAN) architecture also supports Intel’s FlexRAN. Harmeet Chauhan, president, software and internet at Aricent, ...

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 ...
