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…
10BASE-T1S brings a single pair of wires to the network edge
The 802.3cg Ethernet standard uses a single pair of wires, and it manages data flow without switches, making it suitable for industrial networks at a lower cost than traditional Ethernet. Industrial plants have long used digital data to monitor and control their production facilities. Networks in factories, data centers, and commercial buildings push the edges…
Small footprint 3GPP 5G conformance test systems perform RF and radio-resource tests
Rohde & Schwarz has developed two additions for its R&S TS8980 family: the R&S TS8980S-4A and the R&S TS8980FTA-3A.
Cellular SoC includes RF amp, power management, GNSS, NB-IoT, and DECT NR+
Nordic Semiconductor announces the expansion of its nRF91 Series cellular IoT devices with the introduction of the nRF9151 System-in-Package (SiP). The nRF9151 further enhances Nordic’s end-to-end cellular IoT solution, which encompasses hardware, software, tools, and nRF Cloud Services, providing advanced capabilities and seamless integration to significantly simplify the development process. The nRF9151 offers a compact,…
How do you test an Open RAN installation?
Open RAN telecom networks need testing for each disaggregated component, but that’s not enough. End-to-end testing is also necessary. In How do Open RAN interfaces work?, we covered how Open RAN redefines traditional RAN architecture by disaggregating it into three primary components: the radio unit (RU), distributed unit (DU), and centralized unit (CU). This paradigm…
Wireless tester performs Wi-Fi 7 PHY and MAC layer tests
Keysight’s E7515W lets you test Wi-Fi 7 chipsets and systems. As Wi-Fi 7 (802.11be) chipsets, routers, access points, and mobile devices come into production, engineers need to test them for RF conformance and for protocol functionality. Keysight automates those tasks by adding Wi-Fi 7 testing with the E7515W. A variant on its UXM test platform,…
GPS at 50: Now what?
EE World interviewed Microchip’s David Chandler and Duke Buckner on the status and future of GPS, a technology we rely on for location tracking and network timing. Ethernet isn’t the only ubiquitous technology invented in 1973. GPS, the network of satellites that provide location and timing information, was also born that year. GPS has come…
Reconfigurable intelligent surfaces: what, why, where, and how?
Metamaterial arrays allow the wireless medium and path to be “adjusted” to compensate for its many imperfections and changes.
PAs, LNAs boost cellular signals inside vehicles
Guerrilla RF, Inc. announces the formal release of two ¼ W linear PAs and two LNAs earmarked specifically for the automotive market. All four devices were qualified to meet rigorous AEC-Q100 quality standards – a critical benchmark for semiconductor devices used within automotive applications. These new PAs and LNAs are used primarily in cellular compensators (essentially…
