The infrastructure of data communications networks needs lots of fiber, semiconductors, and network equipment to bring data to the masses. Optical data networks form the backbone of today’s communications. Data centers, which seem to dominate any discussion of digital communications, depend heavily on fiber-optic connections from a few meters to many kilometers. Getting those bits…
Our 2024 Communications Handbook is here
EE World announces its 2024 5G, Wireless, & Wireline Communications Handbook in digital form. It’s that time again. EE World’s 2024 5G, Wireless, & Wireline Communications Handbook is here. The 41-page e-book contains ten technical articles plus an editorial. This year, we cover: Network timing, mmWaves (two articles), Power amplifiers (three articles), test & measurement…
RF power transistor delivers 2500 W
The ART2K5TFUS and ART2K5TFUG power transistors from Ampleon amplify signals from 1 MHz to 400 MHz.
5G software stack runs on small cell PHY SoC
Integrate a 5G Open RAN L1-L3 software stack into a small-cell design.
OFC 2024: It’s AI or die
Today’s data rates are already too slow, and so are tomorrow’s. Expect more complaints about slow networks in 2025.
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.
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…
Ethernet turned 50 in 2023, what’s next?
EE World interviewed John D’Ambrosia, who told a few stories from earlier times and gave a peek at what’s coming next from the IEEE 802.3 set of standards.
How trace roughness, glass weave, and stackup affect signal integrity
How do circuit board materials and construction affect the integrity of signals that travel across the board?
