ORAN or Also Ran? A New Generation of RAN Interoperability Begins to Gel

IEEE CTN Issue: September 2018

When you read this article you will note that I stole the excellent “Also RAN” quip from the author, Joe Madden who, following on the heels of a big ORAN meeting in August, provides us with an inciteful view of the ORAN interoperability effort, comparing it to the OBSAI/CPRI efforts in the 3G era and pointing out some new technical challenges brought about by 5G. As we learned from OBSAI and CPRI these kind of efforts come with tremendous promise of change but also with tremendous obsticles to implementation, both technical and political. Your comments, rebuffs and cheers are welcome as always in the comment section at the bottom of the article.

Coding for Distributed Computation on the Edge: Enabling Robust and Resilient Edge Computing in a Service Oriented Network

IEEE CTN Issue: August 2018

Edge compute is seen as an important part of future high bandwidth 5G networks, but it comes with the challenges of distributed compute over a network with variable availability of bandwidth and compute capacity due to the service orientated nature of modern wireless networks. This month Songze and Salman present distributed coding of computation as a technology to combat these issues, outlining two new strategies to balance compute and network bandwidth requirements to optimize the Edge compute QoS. Fascinating stuff. Your comments as always are very welcome.

Coding the Network: Next Generation Coding for Flexible Network Operation

IEEE CTN Issue: July 2018

This edition we take a look beyond the latest codes used in 5G and other transmission standards towards coding designed to support the network rather than just the link. Flexible and multi layered coding techniques are just beginning to get some traction especially, in this editor’s experience, in coding for redundant storage. But Kerim, Muriel and Kavim paint a much larger use case picture while explaining the basic principles. Your comments and questions are, as always, very welcome.
