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…
How IEEE 1588 synchronizes 5G Open RAN
The three units that comprise Open RAN 5G networks need precise timing to properly interoperate. Standards dictate what is needed, but it’s up to design engineers to properly implement timing circuits. 5G networks, with their promise of increased bandwidth and improved responsiveness, impose new challenges on equipment designers and network architects. One such challenge comes…
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…
How timing propagates in a 5G network
5G’s high speeds place extreme demands on the components that maintain accurate time. Compliance with industry timing standards calls for accuracy in the face of temperature changes, shock, and vibration.
Synchronizer keeps 5G networks on time
The Zyntai network time synchronizer from Net Insight picks up where precision-time servers leave off. Without timing and synchronization, networks would simply not run; data would never arrive at its destination. That’s where network timing products come in. At MWC 2023, Swedish network equipment vendor Net Insight will demonstrate Zyntai Time Node and Zyntai Director,…
RF over fiber: overcoming an inherent transmission-line problem, part 1
Optical fiber can carry analog RF signals from antenna to receiver with far less loss than coaxial cables.
ICs and software synchronize Open RAN networks
The Si55xx and Si540x timing ICs from Skyworks work in tandem with AccuTime software to provide low-jitter clocks and IEEE 1588 PTP fronthaul sync. In networks, timing is everything. Without solid, accurate timing and synchronization, data gets lost. Skyworks has introduced ICs that work with its software to address the timing relative to 5G radios…
Synchronizing 5G networks brings timing challenges
Frequency synchronization in the radio access network (RAN) minimizes disturbances at the air interface, ensures mobile handover between radio base stations, and fulfills legal and regulatory requirements associated with a frequency license.
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.
Oscillator shrinks size and power
The Elite X Super-TCXO from SiTime provides stable timing from 1 MHz to 60 MHz for edge computing, vehicles, and cellular base stations.
