Abstract

With an ever increasing appetite for data over wireless networks, one is forced to think where the additional capacity in the wireless networks come from to carry the traffic? Some would argue that additional spectrum needs to be made available or a substantial increase in spectral efficiency has to come by. However, notwithstanding the above, an additional area that has important implications is to evolve seamless and non-seamless session mobility across disparate access technologies such as WiFi to offload some of the traffic to these alternate networks. Similarly, selective handover of specific flows across smaller cells such as Femto and Pico cells of the same access technology will have an impact on the overall capacity of the network. This not only will improve the capacity of these networks but may also enhance the quality of experience for users.

Author Biography

Ajay Rajkumar, Alcatel-Lucent, 600 Mountain Avenue, Murray Hill, NJ, USA

Ajay Rajkumar is Director, Americas Wireless Chief Technology Office at Alcatel-Lucent. He holds a BS (Honors) in Mathematics from Delhi University, MS in Computer Science from Pune University and received a Ph.D. in Computer Science from Courant Institute of Mathematical Sciences, New York University.
During more than nineteen year in the wireless industry, first at Bell Labs Research and then inWireless Division research, Dr. Rajkumar has led and worked towards extending the cutting-edge of technology in modeling, service applications, network performance, end-to-end wireless network architectures, and various standards. He has worked on the evolution of flatter and efficient Network Architecture and Mobility Management for the Next Generation Networks such as LTE/SAE, UMB, and WiMAX. Dr. Rajkumar led the RAN architecture design for efficient service and application enablement, design of Mobile Edge-Content Delivery Network, EVDO Base Station Router design, and the first prototype for Push-to-Talk onCDMAPacket Data Networks. He was an early proponent and developer of IP Backhaul. He has more than two dozen patents received and pending.
Dr. Rajkumar is a Member of Alcatel-Lucent Technical Academy, Distinguished Member of Technical Staff, and a recipient of Bell Labs President’s Award in 2002 and 2005. He is currently the Chair of the Eastern US Chapter of Alcatel-Lucent Technical Academy. In the past, he has chaired several international conferences. He has been an invited speaker at universities and industry forum.
Dr. Rajkumar also led the wireless industry to develop standards for maintaining seamless session across heterogeneous access networks especially for real-time applications thus enabling networks towards providing ubiquitous coverage. He was the founding Chair of IEEE 802.21 Working Group on Media Independent Handover Services and a member of IEEE 802 Executive Committee from 2004–06.
