Abstract

This talk describes high-speed Internet access over quasi-stationary wireless channels between a basestation and a number of residential customers. Orthogonal Frequency-Division Multiplexing achieves robust channel transmission and permits non-line-of-sight operation through advanced beamforming techniques at the receiver. Clever partitioning of modem functions between a high-speed DSP and a highly integrated ASIC yields a cost-effective yet flexible chipset architecture. Deployment issues and examples of the first field trials of broadband wireless access are discussed.

Biography

Michael Polley received his B.S., M.S., and Ph.D. degrees in electrical engineering from the Massachusetts Institute of Technology in 1990, 1990, and 1996. In 1996 Mike joined the DSP Solutions R&D Center of Texas Instruments to help TI influence the DSL standards bodies and enter the ADSL market. From 1997 to 2000, Mike was manager of the ADSL research group developing DSP based solutions for evolving DSL standards. Since then, Mike has come unwired; he currently leads the Broadband Wireless Access Systems team, helping TI establish a leading role in fixed-wireless access technology.
