Abstract- In recent years the increase in the number of wireless client devices within a single wireless local-area network (WLAN) combined with the fact that each of these devices now demand higher bandwidth to support applications such as streaming high-definition (HD) video has sparkled the need for ever faster WLAN systems. Since the adoption of the first 802.11 standard in 1997, the maximum available data rate offered by the latest WLAN system has increased exponentially and is about to surpass the 1Gbps barrier. This increase in throughput is primarily achieved by utilizing multiple-input multiple-output (MIMO) technologies, offering larger channel bandwidths, and more complicated modulations of up to 256-QAM. This paper describes some of the technical challenges and potential solutions in implementing such high throughput wireless systems.
Masoud Zargari received the B.S. degree in electrical engineering from Tehran University in 1989 and M.S. and Ph.D. degrees in electrical engineering from Stanford University, Stanford, CA, in 1993 and 1997 respectively. From 1996 to 1998 he was a member of the technical staff at Wireless Access Inc., Santa Clara, CA. where he worked on the design and development of wireless systems for two-way messaging networks. In 1998 he joined Atheros Communications as a member of the founding team. He is currently a Senior Director of Engineering at Qualcomm-Atheros focusing on integrated CMOS transceivers for wireless communications. During 1999 and 2000 Dr. Zargari was a consulting assistant professor at Stanford University where he taught courses in the area of RF and analog integrated circuit design.
