Leader, 5G Radio Technology, Huawei, Canada
David Wessel is Leader, 5G Radio Technologies at Huawei Technologies, Canada Research Center. He has been with Huawei in various roles in Wireless and Technology R&D since 2009 where his research has focused on advanced Radio Access technology development in both sub 6Ghz and millimeter wave components, circuits and systems. He was employed from 1991 to 2009 with Nortel Networks in capacities ranging from RF amplifier systems to advanced radio architectures for wireless systems. Previous to Nortel he worked in advanced radar amplifier technology research.
Radio hardware challenges for 5G systems
5G systems, as currently envisioned in both sub-6GHz and Millimeter Wave bands present new challenges for radio systems design and deployment. M-MIMO and mmWave will require new views on radio hardware design and implementation as well as new technology ecosystems to overcome cost, power, weight and size issues. New technology advances will be required and a change in view of how we design overall radio architectures and partioning.
