Strengthening the backbone for 5G and beyond

CTN Issue: August 2016

This month we take a look at the optical transmission that without which all of the fancy wireless systems would not be able to access the internet. The bandwidth pressure on the optical backbone will be at least as intense as it is on the wireless access. But never fear, the engineers in this area are also making strides. So this month we hear from Kevin and Yu Rong at British Telecom on their recent successful trial of a 3Tb/s super channel, as well as some of their thoughts on the future for optical networking. As always, your comments are welcome.

Revisiting Cloud RAN from a Computer Architecture Point of View

CTN Issue: July 2016

This month we have asked Prof. Trevor Mudge's team to give us an update on some of the work they are doing in cloudRAN L1 architecture. Trevor's team has a best in class reputation for computer architecture generally and comes at this problem from that view point. In particular Qi's thesis [1] is well worth a read. We hope you enjoy their summary below. Comments always welcome.

5G Moves into the light: Holographic massive MIMO

CTN Issue: June 2016

This month we highlight new technology that uses optical holographic methods to literally image the signals coming off the massive MIMO antenna array, avoiding a lot of the difficult issues with ADC cost and beam processing. Could this be the missing technology to bring practical mMIMO to the field? We thought it was fascinating. Your comments are most welcome.
