u-blox has announced F10, the company’s first dual-band GNSS (Global Navigation Satellite Systems) platform combining L1 and L5 bands to offer enhanced multipath resistance and meter-level positioning accuracy. The platform caters to urban mobility applications, such as aftermarket telematics and micromobility. Applications that use GNSS receivers for accurate positioning are on the rise. Yet, current…
Researchers develop frequency-selective surfaces
The growing number of devices connected to wireless networks has highlighted the need for innovative solutions to ensure seamless connections. Now, researchers from Nagoya Institute of Technology have introduced a metasurface that can distinguish wireless signals based on both frequency and pulse width. This metasurface can be integrated into antennas to accommodate more devices within…
How does a 224 Gbps-PAM4 connector work?
Designing 224 Gigabits per second four-level pulse amplitude modulation (224 Gbps-PAM4) interconnects is challenging. But it’s required to support the demands of generative artificial intelligence (AI), machine learning (ML), 1.6 Terabits per second (Tbps) networking, and other high-speed applications in advanced data centers, as well as 5G and 6G communications infrastructure. At these elevated data…
Open RAN: Interoperability is not plug-and-play
EE World spoke with Adam Smith of LitePoint about the progress and challenges of Open RAN interoperability and testing.
Module simulates 8×8 MIMO for 5G testing
Anritsu Company introduces its Butler Matrix 8×8 MA8118A module that simulates 8×8 MIMO connections for efficient 5G UE throughput tests. Designed for use with the industry-leading Radio Communication Test Station MT8000A, the MA8118A Butler Matrix is a transmission path with 8 input and 8 output ports and supports the 0.6 GHz to 7.125 GHz 5G Frequency…
What’s the difference between an Ethernet extender and a media converter?
Extend the reach of Ethernet by converting the signals to different electrical or optical signals. Ethernet extenders and media converters can both be used to expand network coverage. Extenders operate over unshielded twisted pair (UTP) or coaxial cabling, while media converters change the signals from electrical to optical and back. Extenders and media converters can…
