Wireless Communication Standards

Todor Cooklev has been with San Francisco State University since 2002 where he teaches courses and conducts research in the area of wireless communications. During 1999–2002 he was with Aware, Inc. of Bedford, MA and Lafayette, CA. Prior to joining Aware he was with US Robotics, later 3Com Corporation, where he received the 3Com Inventor Award. In addition to wireless communications, he has worked in the area of voice band modems, DSL technology, and digital signal processing. He also has experience in consulting for government organizations and private technology and venture capital companies. Dr. Cooklev has given a number of short courses, seminars, and invited talks and has also made contributions to the IEEE 802.11, 802.15, and 802.16 families of standards. He is a member of the IEEE Standards Association and has served the IEEE in a number of volunteer capacities. He is also on the Advisory Board of the IEEE International Conference on Telecommunications. He received the Ph.D. degree in electrical engineering from Tokyo Institute of Technology, Tokyo, Japan, in 1995, and also received a NATO Science Fellowship Award in that same year. He is the inventor on several patents in the United States and author of a number of publications in the areas of communication systems, protocols, and signal processing.
