"Next-Generation Wireless Solutions for the Real World: Theory, Practice, and Opportunities"


Noteworthy challenges and ripe opportunities are unfolding as 5G cellular systems rollout and future 6G systems are imagined. Such systems make use of high carrier frequencies, wide bandwidths, and dense antenna arrays to meet the high-rate, low-latency demands of modern applications. In this talk, I highlight how next-generation millimeter wave (mmWave) transceivers can be upgraded with full-duplex capability: the long-sought ability to simultaneously transmit and receive over the same frequency spectrum. By combining theory and practice, I introduce two novel enablers of full-duplex mmWave systems that rely solely on beamforming to cancel self-interference to levels near or even below the noise floor, all while maintaining backward compatibility with beam alignment protocols in 5G. I demonstrate the effectiveness of my proposed solutions using 28 GHz and 60 GHz phased arrays, the first real-world evaluations of their kind. I conclude this talk by forecasting future research directions that will transform the next decade of wireless connectivity.
