Spectrum above 100 GHz provides a promising foundation for realizing unprecedented capabilities in next generation wireless networks. The speaker will begin by describing emerging transmitter and receiver architectures that can realize high-frequency communication and sensing. This talk will then address the key elements needed to realize highly directional, high data rate links that are robust to client and environmental mobility. The speaker will also describe how new sensing capabilities can simultaneously provide millimeter scale resolution without traditional array processing methods used in lower frequency bands. Lastly, physical layer security will be addressed: while narrow beams can make an eavesdropper’s task more difficult, the speaker will describe a new class of “Metasurface in the middle” attacks that yield a formidable adversary. Throughout the talk, experimental results to illustrate current capabilities in these areas will be used.
