Future WLA Ns operating from millimeter wave bands to one terahertz offer both unprecedented capabilities and challenges for mobile communications, sensing, and security. In this talk, I will begin by describing emerging transmitter and receiver architectures that can realize high-frequency communication and sensing. I will discuss key elements needed to realize links that are robust to client and environmental mobility. Moreover, I will show how quasi-optical channel characteristics at terahertz enable a new perspective on wireless sensing. Lastly, I will address physical layer security and resilience to eavesdroppers. Throughout, I will draw on experimental results to explore the gap between idealized theoretical models and real-world systems.
