The radio spectrum above 100 GHz has no active transmitters now in regular use because the technology is only now becoming practical. For several reasons there is a much higher density of passive scientific uses in this spectrum than at lower bands. These passive uses are in highly protected bands but for bands in the 71-275 GHz ITU has acknowledged since 2000 that sharing might be possible with active transmitters. This talk will discuss why transmitter use now is of interest and how the unusual physics of such speaker make the possibility of active transmitters coexisting with passive uses may be possible and the challenges it presents.
Michael Marcus was educated in electrical engineering from MIT. Prior to working at FCC for almost 25 years, he worked at Bell Labs, served in the U.S. Air Force, and analyzed electronic warfare issues at the Institute for Defense Analyses. At FCC his work focused on proposing and developing policies for cutting edge radio technologies such as spread spectrum/CDMA and millimeter waves. Wi-Fi and Bluetooth are results of his early leadership.
He is director of Marcus Spectrum Solutions LLC, an independent consulting firm based in the Washington D.C. area and focusing on wireless technology and policy. He has taught at MIT and Virginia Tech and is now an adjunct professor of ECE and principal research scientist at Northeastern University’s Institute for the Wireless Internet of Things. He was recognized as a Fellow of the IEEE and received in 2013 the IEEE ComSoc Award for Public Service in the Field of Telecommunications "For pioneering spectrum policy initiatives that created modern unlicensed spectrum bands for applications that have changed our world."
