Session Abstract:Exponential growth in wireless data driven by the rapid increase in smartphones is driving carriers to increase the number of base stations in their radio access networks. As the number of base stations increases, it becomes increasingly important that they be made easier to configure, deploy and manage and that optimization and recovery from failures becomes automated. This capability is being labled Self Organizing Network (SON).
SONs use automated mechanisms to configure and optimize themselves. Such networks may use, among other techniques, inter-cell communication as well as feedback from user equipment to configure and optimize themselves. SONs can improve radio channel conditions, filling the holes in network coverage and providing higher user as well as network throughput. We have additional challenges to deal with when SONs use WiFi operating over unlicensed spectrum. Our speakers today will talk about techniques to handle these challenges.

Speaker: Andrea Goldsmith

Bio: Andrea Goldsmith is a Professor of Electrical Engineering at Stanford University with 25 years of experience in the wireless industry. Prior to joining Stanford in 1999, she was an Assistant Professor at Caltech. Her research focuses on state-of-the-art wireless system design. She has published widely on this topic, including three textbooks, and is the recipient of several awards and honors for her research, including IEEE Fellow. Prior to founding Accelera Mobile Broadband, she founded and served as CTO for Quantenna Communications, Inc., a developer of silicon for high-speed 802.11n multimedia home networks. She also served as Chief Scientist at Memorylink Corporation, a developer of broadband wireless backhaul solutions, and has held other industry positions at Maxim Technologies and AT&T Bell Laboratories. She currently serves on the technical advisory boards of Sequans Communications (NYSE: SQNS); Interdigital (NASDAQ: IDCC); and Aviat Networks (NASDAQ: AVNW). Dr. Goldsmith received her BS, MS, and PhD degrees from the University of California at Berkeley.

Abstract: Dr Andrea Goldsmith will discuss the vision of a wireless cloud that implements software defined wireless networking whereby cheap wireless hardware (e.g. small cells and WiFi access points) are extensively deployed, with cloud-based software dynamically optimizing the overall network performance and providing intelligent seamless mobility between WiFi and LTE networks. Dr. Goldsmith will also discuss some of the challenges associated with making this vision a reality. Small cells introduce challenges including interference management between macro and small cells as well as the need for self-configuration. In addition to addressing the spectrum crunch through small cells, the unlicensed spectrum must also be tapped via WiFi. However, WiFi networks suffer from unmanaged interference, unreliable performance, and poor quality-of-experience for the end user. The solution to all these challenges is software-defined wireless networking.

Speaker: Amit Jain

Bio: Amit Jain joined SpiderCloud in September 2011. Prior to SpiderCloud, Mr. Jain was vice president of marketing, sales and service for Airvana's CDMA femtocell business and his tenure at Airvana spanned ten years, including the companys inception. At Airvana, Mr. Jain held several leadership roles in marketing, business development and sales for 3G EVDO macro cellular products and femtocells. Prior to Airvana, Mr. Jain held both technical and business positions at Qualcomm, Ericsson, and McKinsey & Company. He holds an MBA from MITs Sloan School of Management, an MS in Electrical Engineering from University of California at Irvine, and a B.Tech in Electrical Engineering from the Indian Institute of Technology, Bombay.

Abstract: Amit Jain will discuss the challenges of building self-organzing 3G small cell networks and what lies ahead with LTE. Cellular networks are expensive to configure, monitor and optimize. The business case of introducing small base stations (small cells) into the network relies on them being self-organizing. 3G consumer femtocells were the first successful attempt at deploying self-organizing small cells, followed now by 3G enterprise small cells.

Speaker: Rajat Prakash

Bio: Rajat Prakashworks on Small Cells and SON areas in Qualcomm Research and is helping develop solutions to address the 1000x challenge. His areas of interest include mobility performance and protocol architecture in wireless networks. He has participated in several standards bodies including 3gpp, 3gpp2 and IEEE. Recently in 3gpp, he worked on several LTE areas including Home eNodeBs, SON, HetNets, Carrier Aggregation and Relays. Rajat obtained his PhD from the University of Illinois in Urbana Champaign in 2003, Masters from Cornell University in 1999, and Bachelors from the Indian Institute of Technology, Kanpur, all in Electrical Engineering.

Abstract: Rajat Prakash will discuss the key features of the Neighborhood Small Cell model, and highlights of Qualcomm's UltraSON. To address the anticipated projected 1000x traffic increase in wireless networks, the industry is moving to small cells deployments that utilize cell splitting gains. The Neighborhood Small Cell (NSC) model reduces planning efforts for small cell deployments by placing large numbers of small cells at already available backhaul sites in homes and enterprises. UltraSON is a differentiated SON implementation that is tailored for the NSC model, to deal with a dynamically evolving network and maximize capacity and robustness with unplanned small cells.
