GARRET T. OKAMOTO received the B.S. and Ph.D. degrees in Electrical and Computer Engineering from the University of Texas at Austin in 1990 and 1998, respectively, and the M.S. degree in Electrical Engineering from Stanford University in 1991. In 1998 he joined Santa Clara University and is currently Assistant Professor of Electrical Engineering.

Dr. Okamoto worked for the Communications Systems Research Section at the Jet Propulsion Laboratory in various capacities (Member of Technical Staff, Contractor, Co-op) from 1987 until 1998 and achieved success on a number of notable projects including the Mars Pathfinder TCU and the GOPEX Laser Transmission and Monitoring System (first successful laser transmission into deep space). He also worked as a Member of Technical Staff at Sandia National Laboratories, specializing in failure analysis of radiation-hardened devices.

Smart Antenna Systems for WLANs - Developed the Smart Wireless LAN System, which adapts smart antenna techniques for 802.11-compatible wireless LAN systems to increase the range, throughput, capacity, and reliability while reducing power consumption and dead spots. Reduced complexity beamforming algorithms, timing synchronization, QoS measures, implementation issues, etc.

Dynamic Slot Allocation Algorithms - Requires a combination of MAC scheduling, adaptive channel estimation, beamforming, priority designations for data, and reduced complexity slotting algorithms to enable multiple simultaneous transmissions to/from 802.11-compliant users. This would enable up to 8 simultaneous transmissions over an 802.11 channel where current products are limited to a single user at a time.
