Experimental characterization of a hybrid fiber-wireless transmission link in the 75 to 110 GHz band

We present a detailed experimental investigation of a hybrid optical-fiber wireless communication system operating at the 75 to 110 GHz ( W -band) for meeting the emerging demands in short-range wireless applications. Measured W-band wireless channel properties such as channel loss, frequency response, phase noise, and capacity are reported. Our proposed system performs a sextuple frequency up-conversion after 20 km of fiber transmission, followed by a W -band wireless link. A 500 Mbit/s amplitude shift keying signal transmission is experimentally demonstrated for performance analysis purposes.
