Solution Marketing Lead
Dr. Konstantinos Stavropoulos develops and executes the marketing strategy for EXFO's mobile network (access, core, end-to-end) monitoring/optimization solutions, which include intelligent software platforms and expert professional services. His main areas of focus are 5G, 4G evolution, network virtualization/transformation, analytics, and automation. In addition to EXFO’s 5G solutions and market positioning, he actively contributes to the promotion of EXFO’s solutions for automated operations and fiber monitoring.
Konstantinos has been focusing on mobile networks for more than 20 years, through academic and professional roles. His experience covers diverse areas, from antenna array systems research and mobile network planning/optimization consultancy to the development/management/marketing of innovative software solutions. These solutions have supported automated planning/optimization, customer experience geolocation, device interoperability and acceptance testing, service assurance for physical/virtual networks, centralized and automated operations, and (big data) analytics. Konstantinos holds a PhD in electrical and electronic engineering from Imperial College London, has presented at dozens of conferences and webinars, and has authored several articles, blogs and white papers on mobile networks.
Has 5G made mobile radio access a hot topic of discussion again? Perhaps. Is the radio access network (RAN) attracting more attention because of architectural changes, especially those required by network virtualization/cloudification and the move to open (non-monolithic) architectures? Maybe.
Whichever the case, mobile RAN has been evolving for a number of years, gradually taking a multifaceted new—effectively “hybrid”—form (including but not limited to “physical” and “virtual” or “cloud” RAN). This has also impacted RAN-related challenges.
In fact, many challenges are similar to those encountered in the past (e.g., spectrum availability). Some have become more complex (e.g., RAN optimization). Some are due to the different nature of supported use cases. And there are also new (e.g., fiber and cloud network infrastructure) challenges following the RAN disaggregation and the adoption of IT concepts. So, if we consider all challenges—and benefits—together, are we now better or worse off with the new RAN?
Our webinar is based on mobile industry experience and engagements with leading network operators worldwide. Join us for a lively discussion, ask questions in the Q&A session and decide if the new (hybrid) RAN is a “beauty” or a “beast”!
