5G, Social Justice and the role of the IEEE ComSoc

IEEE CTN Issue: August 2015

A few weeks ago, for my sins, I was transportation and security for a crowd of high-spirited teenagers heading off to a youth gathering in Detroit. Each evening the event organizers had a big get-together in the Ford Center, where they packed 30 thousand kids and their adult chaperones in for an evening of unreasonable enthusiasm, unbearably loud music and a few quite interesting talks. There was a lot of talk of social justice at this event; and what all these young folk could, and should, do to help Detroit get back on its feet. In particular, one young lady told us of the Empowerment Plan:  a company she had created based on a class project...

The Death of 5G part 2: Will analog be the death of massive MIMO?

IEEE CTN Issue: June 2015

The exponential growth of data rate has led to the demand for 5G wireless systems with an expected data bandwidth of several GHz and carrier frequencies in the millimeter wave range (tens of GHz to 100GHz) [1-5].  Due to large propagation losses at this frequency range, beamforming with massive MIMO plays a central role in establishing reliable communication links. It is expected that the required number of antennas will be an order of magnitude larger than existing wireless systems. This presents significant challenges in the analog front end design.

Will Densification be the Death of 5G?

IEEE CTN Issue: May 2015

A vast majority of the increased mobile data throughput we are always hearing about has been enabled by ever-increasing network densification, i.e. adding more base stations (BSs) and access points that have a wired backhaul connection [1]. This trend is set to continue for the next decade at least, primarily through the provisioning of small cells such as pico and femtocells. What if we ever reached a point where adding more infrastructure did not allow increased wireless network throughput? This would be comparable to the impending end of "Moore's Law"; a cataclysmic event having far-reaching consequences (i.e. beyond our own industry).
