Keynote Title: Reconfigurable Intelligent and Holographic Surfaces for Wireless Communications

Abstract: A Reconfigurable Intelligent Surface (RIS) is a planar structure that is engineered to have properties that enable the dynamic control of the electromagnetic waves. In wireless communications and networks, RISs are an emerging technology for realizing programmable and reconfigurable wireless propagation environments through nearly passive and tunable signal transformations. RIS-assisted programmable wireless environments are a multidisciplinary research endeavor. This presentation is aimed to report the latest research advances on modeling, analyzing, and optimizing RISs for wireless communications with focus on electromagnetically consistent models, analytical frameworks, and optimization algorithms. In addition, the interplay between RISs and holographic surface-based transceivers will be discussed with focus on near-field communications in line-of-sight channels.

Keynote Title: Going Long: The Future of Low Frequency Communications

Abstract: In this talk we consider how low frequency wireless communications will evolve and become integrated into wireless networking systems. Cellular 6G will add higher frequency operation to the multi-radio mix, providing high-bandwidth in line-of-sight conditions with miniature arrays that can be matched with intelligent reflective surfaces and be used by autonomous air and ground vehicles. In the future, the desire for penetration and persistent robust connectivity in dense and cluttered environments will lead to the incorporation of low-bandwidth low-frequency radios. Evolving low frequency standards will build upon advances in electrically small antennas, cognitive networking, and multi-agent autonomy. The resulting addition of low frequency radios will enable new tools for ad hoc networks for disaster response, topology tracking and network management, indoor/outdoor operations, sensing and situational awareness, and autonomous vehicle networking.

Keynote Title: Communication Models and Protocols: Syntax, Semantics, Pragmatics

Abstract: Wireless connectivity augments human capabilities beyond their natural domain, enabling operation and interaction with objects and subjects placed within an extended space-time domain. This talk will relate the notions of semantics and effectiveness of data transmission to the real-time aspects of communication. We will discuss the general concept of timing in wireless communication systems and networks and its relation to effective information generation, processing, transmission, and reconstruction at the senders and receivers. Starting from latency, a specific instance of timing being in the focus of 5G, the talk will present a statistical framework of timing requirements in wireless systems. This framework can accommodate various notions of correctness, semantics, and effectiveness of information transfer. The talk will discuss how timing can be optimized in various communication models, ranging from point-to-point links and up to models for distributed learning/inference and consensus.
