"Optical Wireless Technologies: Opportunities and Challenges in beyond 5G" with Alexis A. Dowhuszko
On 6 February 2026, at 10:30, the Blue Room of the TeCIP Institute will host the seminar entitled “Optical Wireless Technologies: Opportunities and Challenges in Beyond 5G”, delivered by Dr. Alexis A. Dowhuszko.
Abstract
5G relies on dense network deployments and advanced technologies such as millimetre-wave communications, massive MIMO, network virtualization, and slicing. However, its key performance indicators will not be sufficient to meet the demands of services expected by 2030, including massive machine-type communications, 3D service areas, and ultra-high data-rate Beyond-5G (B5G) use cases. In addition to higher throughput, reliability, latency, and scalability, future networks must also address new requirements such as sensing and positioning, security, privacy, trust, and sustainability.
Optical Wireless Communication (OWC) has emerged as a promising complement to Radio Frequency (RF) systems, which are increasingly constrained in meeting these demands. OWC offers ultra-dense deployments with low interference, high energy efficiency, inherent physical-layer security, electromagnetic compatibility, and access to a license-free spectrum with higher allowable transmit power.
In this presentation, we start with an overview on the common characteristics of OWC systems, making emphasis on the differences that exists between laser-based and LED-based technologies used for (long-range) point-to-point and (short-range) wireless access links, respectively. Then, we present some key results on different OWC systems, focusing on the opportunities that this new technology has to offer in the B5G landscape. Finally, we present a vision on the activities that should promote the adoption of OWC technology, reflecting on the challenges that are delaying its massive use.
Short Bio
Dr. Alexis A. Dowhuszko is a Doctor in Engineering Sciences, currently serving as a researcher and project specialist at the Department of Information and Communications Engineering, Aalto University, Finland. He received his Telecommunications Engineering degree from Blas Pascal University (Argentina) and his Ph.D. in Engineering Sciences from the Universidad Nacional de Córdoba in 2010.
Dr. Dowhuszko’s research spans advanced wireless and optical communication systems, including experimental optical wireless links, 5G New Radio technologies, and next generation 6G networks. His work bridges theory and practice, addressing topics such as physical layer link adaptation, resource allocation, and system-level performance analysis across both optical wireless and radio domains.
Prior to his current role at Aalto University, he conducted postdoctoral research in Finland and held a senior research position at the Centre Tecnològic de Telecomunicacions de Catalunya (CTTC) in Barcelona. Across his career, Dr. Dowhuszko has contributed to the development of disruptive communication technologies, and his work has been published in top peer-reviewed venues and supported by collaborations with international research groups.
