Faculty Host: Thomas Little

Refreshments will be served outside Room 339 at 3:45 p.m.

Abstract: For the past fifteen years, wireless local area networks have operated successfully in the 2.4 GHz band and the 5 GHz bands. Signals from these bands do not confine themselves to a given room or even household, so security and frequency re-use are issues for concern. Alternative frequencies such as 60 GHz or optical wireless links are currently being investigated as alternatives to these leaky lower bands.

This talk will give an introduction to some of these transmission methods and then focus on diffuse optical wireless communications. A proposed method for sending information via light is asymmetrically-clipped optical Orthogonal Frequency Division Multiplexing (ACO-OFDM). Some recent results for ACO-OFDM are presented and discussed.
