5G Cellular Networks with Prof. Ekram Hossain

This week we were delighted to welcome Professor Ekram Hossain from the University of Manitoba, Winnipeg, Canada. Professor Hossain is a well-known IEEE fellow, author and editor in ‘Communication Networks’ publications, and is the main lead for the ‘Wireless Communication, Networks and Services (WiCoNS)’ research group at Manitoba.

The presentation included and discussed current 3G and 4G technologies, licensed and un-licensed spectrum bands, multiple and co-existing architectures, the latitude of networks for users and providers, as well as the fabrications needed to support a clear rise in user density on mobile networks. Examples of such support and architectural enhancements are smaller base stations known as femtocells, picocells, and microcells. These stand in contrast to current macrocells which are commonly known as cell towers.

Professor Hossain further described the radio spectrums as ‘invisible real-estate’. Just as we try to become more environmentally efficient in everyday life by using greener technologies, for instance running our homes with energy harvested through solar panels, and cars running on electricity, we must also try to run greener cellular radio systems. ‘Energy harvesting’, a form of long-range induction charging through smart- and network-devices, could prove to be a highly efficient and intelligent way of conducting resource management.

The presentation concluded with a fantastic follow-up discussion on security, related and evolving technologies, and the deeper aspects of multi-tier architectures.

We would like to thank Professor Hossain for travelling all the way from Canada to deliver an exciting and insightful presentation, and we would be delighted to see him again in the near future. Until then, we wish him all the best and continued success with his exciting research.
