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,…
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…
6G conference exhibits demonstrate possible technologies
At the 6G Symposium and 6G Summit, attendees saw the latest research that could lead to the next generation of wireless.
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…
Signal generator tests 5G FR1, LTE, Wi-Fi components and systems
Designed for bench and production use, the N5186A generates wireless signals to 3 GHz, 6 GHz or 8.5 GHz depending on model. Designing commercial or military wireless receivers, amplifiers, and systems means you’ll need to generate test signals. Keysight’s N5186A MXG vector-signal generator (datasheet) is available in one-channel or four-channel models with Type-N connectors. Each…
Maxwell’s classic Treatise returns after 115 years
New Bedford, Mass. — In June 2023, a rare 1881 copy of James Clerk Maxwell’s An Elementary Treatise on Electricity turned up in a West Virginia library. In remarkably good condition, the book was returned to its original library in New Bedford. The book was last checked out in what looks like 1908, making it…
How RF measurements verify satellite links
Noise measurement, LO substitution, receiver stress testing, power measurement, CCDF and PAPR characterization, and antenna-pattern measurement play critical roles in link budget, bit-error rate, and SNR requirements. Low-Earth orbit (LEO) satellite systems are being deployed for mission-critical use cases at an accelerating rate. This brings associated critical test requirements that, if not performed accurately, could…
EE World’s 2023 communications handbook is here
Our 2023 5G, Wired, & Wireless Handbook is now available in ebook form. Download your copy today. It started on a cold January day with an editorial call. A month later, the abstracts came in. After another month, the manuscripts came in. Then came the editing and some back-and-forth with the authors. Next, it was…
5G mmWave test builds on RF best practices
The high level of integration in today’s mmWave phone means traditional test methods no longer apply.
