Spotlight on Young Researchers: Connectivity for all


Over one third of the global population still struggles to connect to the Internet: This leaves especially people in rural areas cut off from the rest of the World, hindering opportunities for growth. To ensure connectivity for all, researchers are working to enhance multi-beam satellite systems, with the goal to provide cheaper, demand-driven broadband internet services.

“The problem with current satellite systems is that they are not designed to adjust to changes in demand profiles. This can lead to issues such as overloaded or underused satellite beams, poor SINR performance, and interference. In simple terms, current satellite systems manage radio resources very poorly. To address this issue, my research focuses on interference mitigation and resource allocation techniques for dynamic beam-forming satellite systems,” explains Puneeth Jubba Honnaiah, Telecommunication scientist working on a collaboration between SnT and SES S.A.

The research Puneeth works on specifically revolves around developing adaptive systems that can adjust to changes in demand profiles.

“Techniques such as demand-driven beam densification, adaptive multi-beam pattern and footprint optimisation, and user scheduling algorithms have made sure that more people in remote areas can enjoy lightning-fast, reliable, and affordable broadband internet services, even in places where it’s traditionally been difficult to get online,” Puneeth explains.

The challenge: Adaptive satellite systems

One of the main challenges in this field of research is developing dynamic beamforming satellite systems that can adapt to the ever-changing needs of users and environments: This requires advanced algorithms and techniques for real-time resource allocation, interference mitigation, and beam pattern design that can optimise satellite systems to provide reliable and affordable broadband internet services – even in the most remote and challenging areas.

The development of innovative technologies that can reduce the cost of satellite infrastructure and improve the efficiency of spectrum usage also remains a critical challenge in the field.

The main obstacles standing in the way of solving these challenges are the limitations of existing technology and our current knowledge of complex systems. There is still much to learn about how to optimise dynamic beamforming satellite systems for real-time resource allocation, especially in changing and unpredictable environments.

However, progress is being made, and with continued investment in research and development, the obstacles and bring affordable, reliable, and high-speed internet services to everyone, everywhere.

Eliminating digital barriers using machine learning methods

Using optimisation techniques, machine learning methods, and real-time resource allocation strategies, Puneeth’s research aims to create adaptive satellite systems that can quickly and efficiently adjust to changes in user demand and environmental conditions. rn

“By designing more efficient and effective beam patterns, we are also working to increase the coverage and capacity of satellite systems. This will make them more accessible and affordable for people around the world.”

My research has contributed to the development of novel adaptive techniques for satellite internet services. Through my investigations, we have identified effective approaches for improving demand satisfaction and throughput performance in satellite internet services. Additionally, with my work, we can now have more efficient spectrum and interference management in demand-driven dynamic systems.

“Overall, my research has the potential to significantly improve internet access for individuals and communities in remote rural areas and even mid-ocean ships and mid-air flights, helping to bridge the digital divide and promote connectivity for all.”

Puneeth Jubba Honnaiah is a telecommunication scientist Completed PhD in 2022 and at the time of writing works as a research associate (postdoc) at SnT, SIGCOM research group, University of Luxembourg. The project runs in the framework of an FNR Industrial Fellowship, which supports collaboration between academia and industry.
