Timing module extends the life of legacy network equipment

Redding Traiger — Tue, 04 Jun 2024 01:08:37 +0000

Microchip Technology announces the new TimeProvider XT Extension System, a fan-out shelf used with redundant TimeProvider 4100 grandmasters to migrate legacy BITS/SSU equipment to a modular and resilient architecture. The TimeProvider XT provides operators with a clear path to replace existing SONET/SDH frequency synchronization equipment while adding timing and phase, essential for 5G networks. As…

What are 5G’s, the different types, and how are they used?

Aharon Etengoff — Wed, 22 May 2024 10:46:23 +0000

5G is much more than cell phones. IoT devices, medical devices, and industrial devices can connect to networks using technologies such as TDD, network slicing, and beamforming. 5G New Radio (NR) made its long-awaited commercial debut in late 2018. Offering significantly faster speeds and greater capacity compared to 4G Long Term Evolution (LTE), 5G NR…

Build a 5G Open RAN test lab with open-source software tools

Lincoln Lavoie, University of New Hampshire Interoperability Lab — Wed, 20 Mar 2024 09:27:38 +0000

Open-source software provides network components that you can use to simulate 5G network functions from the network core to the radio. Developing and deploying a laboratory infrastructure to support testing 5G and open radio-access network (Open RAN) systems can present a daunting and complex task. Prior to Open RAN, this task was only possible by…

Flexible PTP profiles ease the transition to 5G

Eric Colard, Microchip Technology — Wed, 13 Mar 2024 21:46:21 +0000

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?

Martin Rowe — Thu, 25 Jan 2024 21:59:02 +0000

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…

Why O-RAN sync monitoring needs AI/ML

Ramana Reddy, Rakuten Symphony — Tue, 01 Aug 2023 15:45:47 +0000

As Open RAN deployments gather pace and accurate timing, synchronization has emerged as a critical step toward consistent performance. It is a complex task, with devices requiring time synchronization to UTC reference via IEEE PTP/SyncE-based boundary clocks, slave clocks, PRTC clocks with GNSS receivers, as well as accurate, real-time monitoring in support of customer SLAs.…

How IEEE 1588 synchronizes 5G Open RAN

Lokesh Duraiappah and David Spencer, Skyworks — Thu, 06 Apr 2023 19:00:41 +0000

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

Darrin Gile, Microchip Technology — Tue, 04 Apr 2023 09:00:45 +0000

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…
