Topic: Green Distributed Antenna Systems and Upper Bound for Energy Efficiency
Speaker: Mikhail Popov, Acreo
Abstract: Mobile communication services today are made available through a mobile communication network (e.g. 4G/LTE) which consists of basestations and the packet-based core network. The basestations provide the wireless links to the mobile units, and today’s basestations account for more than 50% of the total energy consumption in the whole mobile communication network. Recent research results show that the energy efficiency (in Joule/bit) of the mobile communication network can be substantially reduced without sacrificing coverage and QoS through applying architectural changes, optimization and directive antennas. In the present work, we have shown that in some cases one can reach a 10-fold or more improvement in energy efficiency. We have also shown that in an integrated optical-wireless system there might be an upper bound for energy efficiency.
Mikhail Popov: Mikhail Popov received the M.Sc. degree (with honors) in Electrical Engineering in 1995 from St. Petersburg Electrotechnical University and the Ph.D. degree in Electromagnetic Theory in 2002 from the Royal Institute of Technology (KTH), Stockholm, Sweden. He joined Acreo in 2001 as a research scientist and project manager. In 2008-2011, Mikhail was the coordinator and technical manager of the FP7 Large-Scale Integrating Project ALPHA – “Architectures for fLexible Photonic Home and Access networks” and also served as Chair for the Converged and Optical Networks cluster of the EC FP7 Future Networks projects. His current research interests include next generation optical and wireless networks, green network planning and operation, QoS provisioning/control plane, and mobile backhaul and fronthaul issues in networks. Dr. Popov has authored and co-authored 80 papers on electromagnetic theory, optical communications and networking. Dr. Popov is a Senior Member of IEEE.
