With the advent of broadband wireless systems operating at microwave frequency bands, and with the entailed shrinkage of cell coverage for high capacity wireless access, the simplification of the antenna stations becomes crucial to reduce access infrastructure cost. For this purpose, radio-over-fiber (RoF) distribution antenna systems are an attractive option for the transparent delivery of wireless data signals from a central office location to remote antenna sites via optical fiber. In this way, the complicated and costly (in particular for high RF frequencies) wireless signal processing can be placed in the central office.
This presentation will give an overview of the Fiber Assisted Wireless for Broadband Access Networks. The approach is based on passive optical network architectures that can support the generation, transmission and delivery of high frequency signals required in wireless links. In addition these architectures allow the sharing of a single central office and provide additional direct interconnectivity of the antenna station so dynamic bandwidth allocation can be addressed as mobile customers enter or leave the coverage area of different cell coverage.
Professor Nicholas Madamopoulos is currently an Associate Professor at the Department of Electrical Engineering, City College of CUNY, New York. He received his B.S. in Physics, from the University of Patras, Patras, Greece in 1993 and the MS and Ph.D. in Optical Science and Engineering, at the The School of Optics, University of Central Florida, Orlando, FL, in 1996 and 1998, respectively. His research interests include optical communications, passive optical networks, analog photonics, photonic sensors, photonic systems for telecom and non-telecom applications.
