Wi-Fi 7 and 5G for FWA need testing
By Xiang Li, Keysight Technologies Follow these three steps to ensure your fixed-wireless access (FWA) designs will be compatible with the Wi-Fi fronthaul and 5G backhaul. Many areas lack the wired infrastructure to bring residential broadband access. Making those connections has become costly and inefficient. Fixed Wireless Access (FWA) has emerged as a compelling alternative…
What to expect from 5G-Advanced
First deployed in 2019 for mobile broadband communications, 5G is now ready for 5G-Advanced, which, for the first time, adds features focused on enterprise use cases starting with 3GPP Release 18. First outlined in 3GPP Release 18, 5G-Advanced (5.5G) (Figure 1) significantly improves network efficiency, latency, throughput, and coverage. 5G-Advanced adds evolved multiple input multiple…
Co-packaged optics: higher data rates increase reliability risks
EE World discussed with GlobalFoundries’ Anthony Yu trends and tradeoffs in co-packaged optics and silicon photonics resulting from the rising data demand that AI thrusts upon us. It’s coming down to speed versus reliability, at least for now.
AI, silicon photonics push networks and test
EE World spoke with Sarah Boen, Director of Technology and ASIC Strategy at Tektronix, who spoke at a panel session on how AI and silicon photonics are changing networks and the challenges facing test engineers and reliability engineers. In OFC 2024: It’s AI or die, EE World reported on how the data generated by AI…
How coherent optical engines send and receive network data
By Paul Momtahan, Infinera Learn about the components inside a coherent optical engine, what they do, and how they use modulation to send and receive data. Optical communications over metro, long-haul, and submarine networks once used simple direct-detect technology. That’s no longer the case. Demand for higher-speed optical connections has brought on complex modulations and…
Wi-Fi 7 and private 5G networks: co-existence or competition?
Integrating Wi-Fi 7 with private 5G in CPE devices can help ensure reliable, gigabit-level speeds, robust security, and centralized management across diverse deployment scenarios. Delivering high speeds and low latency, private 5G and Wi-Fi 7 (IEEE 802.11be) networks offer efficient spectrum use and robust security for a wide range of demanding applications. What are the…
Video: How should 5G, 6G evolve?
EE World spoke with Matsing’s Manish Matta and Keysight’s Roger Nichols on how 5G is evolving into business use cases and where 6G could play a role.
