5G brought architecture changes that require synchronization. Depending on the location and network site, those timing requirements require different PTP profiles and PTP capacity.
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…
Next-gen Ethernet switches incorporate TSN, port bandwidths from 46 to 102 Gbps
Microchip Technology today announces its next-generation of LAN969x Ethernet switches with Time Sensitive Networking (TSN), scalable bandwidths from 46 Gbps to 102 Gbps, and a powerful 1 GHz single-core Arm Cortex-A53 CPU. For applications that require greater redundancy, the LAN969x Ethernet switches can be configured with High-availability Seamless Redundancy (HSR) and Parallel Redundancy Protocol (PRP).…
How to improve Open RAN security at the hardware level
Open RAN telecom network security begins in the microprocessors that control telecom network equipment. Configure and use these processors with secure booting and build trust.
IMS 2023 roundup: semiconductors and microwave components
Through photos and videos, EE World covers some of the active and passive components that RF and wireless engineers need to connect us all.
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…
Open RAN networks pass the time
Network elements must meet certain frequency, phase, and time requirements to ensure proper end-to-end network operation. Synchronization architectures defined by the O-RAN alliance dictate how Open RAN equipment can meet these requirements. Open RAN continues to attract interest from service providers looking to reduce cost, improve competition, and drive technology innovation. The desire for a…
Our second 5G Handbook is now available
Featuring 15 articles, the 2022 5G Handbook looks at private networks, timing, connectivity, latency, mmWaves, test, and other topics.
How timing design and management synchronizes 5G networks
The infrastructure needed to deliver cost effective, reliable, and secure timing throughout cellular networks needs proper architecture, design, and management. Tighter time accuracy demands for 5G networking equipment requires reliable and robust timing architectures that guarantee network performance.
Timing IC combines functions for Open RAN
Microchip’s ZL30735 integrates eight DPLLs, five low-output jitter synthesizers, and an IEEE 1588-2008 protocol stack. The splitting of radio access network functions creates an Open RAN that promises greater innovation and features in 5G networks. Splitting the traditional baseband unit into radio units (RU), distribution units (DU) and centralized units (CU) brings timing issues not…
