The Virtualization Revolution in Cellular: Management, Economic, and Policy Implications

Instructors: Marvin Sirbu (lead), Chris Boyer, Brian Daly, Mike Barnes, Diane Rinaldo 

Course Description: This course describes the long-term trend towards virtualization in cellular systems and its implications for operators, customers, and society. Mobile network operators once built infrastructure from hardware devices tied to a single vendor and replaced them with every new generation. Today, more functionality is shifting to software, often running in cloud servers through technologies like virtualization, software-defined networking, and Open Radio Access Networks (O-RAN). This allows operators to upgrade and customize networks without replacing devices, while also reshaping industry structure and how we view security and privacy. Operators will have more competitors to choose from, potentially driving down prices. The course will explore operational issues from the operator’s perspective, vendor management, security, energy efficiency, and customization for large customers, as well as societal implications, including security, privacy, supply chain trust, opportunities for domestic entrepreneurs, and workforce development.

Intended Participants: The course is designed for professionals from mobile network operators who are involved in infrastructure strategy, cybersecurity, marketing, and vendor relations. It also welcomes government officials engaged in spectrum policy, telecom regulation, infrastructure expansion, and market development. Additionally, representatives from civil society organizations and other stakeholder groups focused on digital access, privacy, and technology policy will find the course highly relevant.
