If you have a question about this talk, please contact Kin K Leung. Please tell Kin K Leung if you are interested in discussing with the speaker. We study the impact of higher-order sectorization (up to 12 sectors per cell site) in cellular networks with low angle spread and a high density of users. We show that under ideal sector patterns (with no intersector interference), the mean throughput per site scales directly with S, the number of sectors per site. Fixing the number of antennas per site to be 12, higher-order sectorization with S = 12 and single-antenna transmission per sector is shown to achieve higher average throughput compared to a conventionally sectorized system with S = 3 and capacity-achieving multiuser MIMO transmission with M = 4 antennas per sector. A circular antenna array architecture is proposed for generating S = 12 sectors using fixed beamforming. Beams generated using an array prototype were measured in an anechoic chamber were shown to achieve a similar response as the one used in simulations, and the wind load improvement is a factor of 8 compared to a conventional S = 3, M = 4 configuration. Bio: Howard Huang was born in Houston, Texas in 1969. He received a BS in electrical engineering from Rice University in 1991 and a Ph.D. in electrical engineering from Princeton University in 1995. Since then, he has been a researcher at Bell Labs (Alcatel-Lucent) in Holmdel, New Jersey, currently as a Distinguished Member of Technical Staff in the Wireless Communication Theory Department. His interests are in communication theory, multiple antenna (MIMO) techniques, and the system design of wireless networks. He served as a guest editor of two issues of the IEEE Journal of Selected Areas in Communications— one on next-generation MIMO wireless networks and another on cooperative communications in MIMO cellular networks. He has taught at Columbia University and is a co-author of the book MIMO Communication for Cellular Networks (published by Springer 2011). Dr. Huang holds over a dozen patents and is a Senior Member of the IEEE . This talk is part of the Featured talks series. This talk is included in these lists:
