Prof. Vivek A. Bohara

The upcoming 6G wireless revolution is poised to go far beyond the traditional radio frequency paradigm, embracing novel technologies that leverage light and smart surfaces to meet the ever-growing demand for ultra-fast, energy-efficient, and intelligent communication. This talk, "Beyond Radio: How Light and Surfaces Are Powering the 6G Revolution,"explores the transformative role of Visible Light Communication (VLC), Terahertz (THz) technologies, and Reconfigurable Intelligent Surfaces (RIS) in shaping next-generation wireless networks. We delve into how light-based communication offers massive bandwidth and enhanced security, while RIS enables smart propagation environments that can dynamically manipulate wireless signals. Together, these innovations promise to enhance connectivity in urban, remote, and space-constrained environments, enabling applications such as holographic communications, autonomous mobility, and the Internet of Everything. The talk will highlight recent breakthroughs, practical deployment challenges, and the road ahead for integrating these technologies into a unified 6G framework.

The evolution of 5G and beyond has placed significant emphasis on high-speed, low-latency communication systems, particularly for massive-Machine Type Communication (mMTC) applications such as Vehicle-to-Everything (V2X) communication. This talk presents the design and challenges of an Advanced Analog Front End (AFE) for millimeter wave (mmWave) communication systems, which are vital for meeting the stringent performance requirements of such applications.

The talk begins with the digital front end, leveraging RFSoC platforms that integrate high-speed DACs, ADCs, and embedded FPGAs. These FPGAs act as hardware accelerators, enabling real-time, high-throughput baseband processing essential for dynamic vehicular environments.

The talk emphasise on the key analog front-end components, including modulators, demodulators, power amplifiers, and low-noise amplifiers, which must operate efficiently at mmWave frequencies under strict performance constraints. The talk further explores beamforming techniques and antenna array architectures that facilitate directional communication, critical for maintaining reliable links in mobile, high-speed V2X scenarios.

The impact of analog front-end impairments such as I/Q imbalance, non-linearity, phase noise, and gain mismatches is discussed, along with performance metrics to quantify and mitigate these effects. These metrics are crucial for ensuring robust communication in safety-critical applications.

By focusing on both digital acceleration and analog signal integrity, the talk provides a comprehensive perspective on enabling high-performance, low-latency communication for V2X systems and other mMTC use cases, which form a cornerstone of 5G and future wireless technologies.
