Behind the research

Author: Mallik Tatipamula, FRS FREng FRSE My previous CHEDDAR article (https://cheddarhub.org/blog/from-iot-to-physical-ai-how-6g-transforms-connected-things-into-intelligent-environments-2/) explained Physical AI as the evolution beyond IoT at the application level. This note complements it by demonstrating that this shift arises from a deeper architectural transition in networks, from packet delivery to workload execution to verifiable multi-agent interaction explaining why 6G must be designed as coordination infrastructure rather than merely connectivity infrastructure. Abstract Mobile networks are commonly interpreted as communication systems whose evolution is primarily driven by advances in radio performance, such as higher throughput, lower latency or improved spectral efficiency. Historical deployment patterns, however, suggest an additional [...]

From Convergence to Continuity in the Design of Intelligent Systems Written by Dr Mallik Tatipamula, FRS FREng FRSE, CTO, Ericsson Silicon Valley    Executive Summary The evolution from connected things to intelligent environments fundamentally changes what infrastructure must guarantee. In the Internet era, correctness meant delivering data reliably. In the era of Physical AI, where autonomous agents sense, decide, and act across the real world, correctness must expand to preserving meaning, intent, trust, and accountability across distributed intelligence. This article introduces cognitive continuity as the missing architectural property of AI-native infrastructure: the ability of systems to sustain coherence as cognition [...]

Written by Dr Laksh Bhatia, Wireless Systems Researcher, Engineer and Innovator, InterDigital, Inc “What is the use-case? Why should we build it?” This has been the guiding principle of my academic and industrial journey. Over the past decade, I have dedicated myself to designing and constructing systems that have since been deployed on over a million devices. My work has encompassed a wide range of areas and has been conducted under different paradigms. From wireless sensor networks to the Internet of Things (IoT), cyber-physical systems, and more recently 6G research, the overarching objective has remained the same: to design efficient [...]

Written by Dr Mallik Tatipamula, FRS FREng This article explores Physical AI as the next step beyond IoT, and why 6G and Integrated Sensing and Communications (ISAC) are critical to enabling safe, intelligent, and resilient physical systems. In recent years, leaders in the AI and robotics community have increasingly framed the next frontier of artificial intelligence as Physical AI or Physical Intelligence: systems that do not merely process information, but perceive, reason, and act in the real world. As Nvidia CEO, Jensen Huang and others have emphasized, the transformative impact of AI will come not from disembodied models alone, but from intelligence embedded in physical [...]

Researchers from the University of York presented their recently published paper, Formal Verification of Physical Layer Security Protocols for Next-Generation Communication Networks, at the 26th International Conference on Formal Engineering Methods (ICFEM2025) on 11 November 2025. Background Physical Layer Security (PLS) is gaining traction as an additional security layer for future communication systems. Unlike traditional cryptographic approaches, PLS secures wireless communication by leveraging the physical characteristics of the wireless channel itself such as noise, interference, fading, and dispersion. While cryptographic protocols have long benefited from formal verification tools that can identify vulnerabilities and rigorously validate security guarantees, PLS mechanisms have not received the same level [...]
