The opening of the 60GHz ISM (Industrial Scientific Medical) band has triggered intense interest in industry as well as academia on how best to exploit the available 5- 7GHz bandwidth. From a network design point of view, this frequency band offers a specific challenge not seen at lower ends of the spectrum (for instance the bands we are more familiar with, between 2-5GHz). At 60GHz, the signal attenuation is high because of oxygen absorption and absorption by many materials commonly used in construction. Therefore, reflected components of a signal tend to be significantly attenuated as compared to a direct path. In this talk, we present SDMA (Spatial Division Multiple Access) algorithms that exploit the peculiar propagation properties of this part of the frequency. We show that in typical indoor environments, one access point can deliver over 8 gbps total throughput.
Candy Yiu received her Bachelors degree in 2001 and M.Phil degree in 2003 from Hong Kong Baptist University. She is currently a Ph.D. student in the department of Computer Science at Portland State University, Portland, OR. Her work focuses on the emerging area of 60 GHz Wireless Networking. This work has been published in several conferences and a journal. Her research interests are performance study in digital communication, architecture design and software defined radio. She is expecting to graduate in summer 2010.
