Challenges and Design Aspects for 5G Wireless Networks John Smee Qualcomm Abstract: After a brief background on the evolution of cellular wireless networks from 1G to 4G, we introduce the technical goals and timeline for 5G. The improvements targeted by 5G include spectral efficiency, energy efficiency, throughput, and latency with a focus on both enhancing mobile broadband and enabling new services. 5G networks will include a continue evolution of network topology and a growing range of technologies and spectrum types including licensed, shared, and unlicensed spectrum. The talk breaks down the challenges and design approaches for the 5G air interface focusing on mobile broadband, mission critical services, and massive IOT. BIO: Dr. John E. Smee is a Vice President of Engineering at Qualcomm Technologies Inc. He joined Qualcomm in 2000, holds 54 US Patents, and has been involved in the system design for a variety of projects focused on the innovation of wireless communications systems such as CDMA EVDO, IEEE 802.11, 3GPP LTE and 5G. His work involves taking advanced system designs and signal processing techniques from theory through design, standardization, implementation, and productization. He is currently a 5G project engineering lead in Qualcomm’s research and development group. John was chosen to participate in the National Academy of Engineering Frontiers of Engineering program and is a recipient of the Qualcomm Distinguished Contributor Award for Project Leadership. He received his Ph.D. in electrical engineering from Princeton University, and also holds an M.A. from Princeton and an M.Sc. and B.Sc. from Queen's University.
