Title
VoIP for Wireless
Speaker
Prof. Henning Schulzrinne, Columbia University
Biography
Prof. Henning Schulzrinne received his Ph.D. from the University of
Massachusetts in Amherst, Massachusetts. He was a member of technical
staff at AT&T Bell Laboratories, Murray Hill and an associate
department head at GMD-Fokus (Berlin), before joining the Computer
Science and Electrical Engineering departments at Columbia University,
New York. He is currently chair of the Department of Computer Science.
Protocols co-developed by him, such as RTP, RTSP and SIP, are now
Internet standards, used by almost all Internet telephony and
multimedia applications. His research interests include Internet
multimedia systems, ubiquitous computing, mobile systems, quality of
service, and performance evaluation. He is a Fellow of the IEEE.
Abstract
IEEE 802.11-based networks are likely to become popular as replacements
for cordless phones, particularly in enterprise settings, and as a way
to fill in cellular coverage inside buildings and homes. However, using
802.11a/b/g for VoIP poses a number of challenges, including how to make
hand-offs transparent, how to maximize capacity and how to limit the
number of concurrent calls to avoid quality degradation. In the IRT Lab
at Columbia University, we have proposed and investigated a number of
techniques that address these issues. In addition, measurements of
802.11 networks illustrate some of the operational and modeling
challenges.
