Technical seminar with the following abstract: The journey of wireless communication has transformed our world, evolving from simple voice calls in 1G to the immersive experiences and massive machine-type communication envisioned for NextG. However, this progress brings critical challenges: sub-6 GHz systems struggle with energy efficiency and sustainability, while mmWave networks face reliability issues and scalability constraints when serving large numbers of clients. This talk introduces groundbreaking solutions to these challenges, paving the way for a more sustainable and reliable wireless future. I will present GreenMO and PhaseMO, innovative approaches that leverage hardware virtualization to dramatically reduce power consumption in Massive MIMO systems, making them more energy-efficient. Additionally, I will present mmReliable and mmFlexible, transformative strategies that enhance mmWave network scaleability and reliability by employing multi-directional beamforming to enable multi-user and overcome blockages and ensure consistent connectivity. Together, these advancements redefine the possibilities for NextG wireless systems. Finally, I will share insights into ongoing research at WCSNG UCSD aimed at creating NextG software driven wireless networks, that can sustain the ever-growing demands of modern communication networks.
