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…

Board-to-board connector line expanded to include 0.635 mm pitch versions
Samtec has expanded its successful line of Edge Rate board-to-board connectors to include a higher density mated set that is half the width of previous designs and offers a lower-profile 5 mm mated height (ERF6 & ERM6 Series). ERF6 & ERM6 Series Edge Rate connectors support 56 Gbps PAM4 high-speed, rugged mezzanine applications for industrial, embedded vision, […]
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,…
Front-mounted IP67 bulkhead jacks added to panel mount receptacles
Amphenol RF is pleased to expand our versatile SMA product portfolio with additional reverse polarity front mount bulkhead jacks. The bulkhead jacks are engineered to accommodate a variety of micro coax cable types including 0.081 mm, 1.32 mm, 1.37 mm, and RG-178 and are IP67 rated. This makes them ideal for applications in demanding environments […]
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…
High-impedance, high-bandwidth oscilloscope probe captures serial bus signals
The Infiniimax 4 active probe from Keysight reaches 52 GHz, enough to see signals on PCIe 6/7, 800 Gb/sec Ethernet, DDR 5/6, and other high-speed serial buses. Oscilloscopes with 100 GHz and higher bandwidths can display signals on 224 Gb/sec PAM4 serial buses and they’ve been available for several years. Without probes of high enough […]
Simulate 5G physical uplink shared channel designs
AccelerComm announced the general availability of its physical uplink shared channel (PUSCH) Channel End-to-End Simulator, a configurable tool that lets telecoms equipment vendors evaluate the company’s IP components. The simulator lets AccelerComm’s own engineers and its customers comprehensively analyse the detailed behaviour of the PUSCH processing components relative to the Matlab 5G Toolbox, a recognised…
What are some disadvantages of unshielded twisted pair cable?
Contributed by Frances Richards Unshielded twisted pair (UTP) cable is comprised of anywhere from two to 1800 unshielded twisted pairs of 100-ohm copper encased in an outer plastic jacket. This widely used data communication cable is most commonly found in local area networks (LANs) for applications such as computer networking, telecommunications, and Ethernet networks. Benefits […]
