Abstract: The Radio Access Network (RAN) forms the backbone of mobile communication systems. Traditional RAN architectures, characterized by tightly coupled proprietary hardware and software, have long dominated the telecommunications landscape. However, with the advent of 5G and the increasing demand for scalable, cost-efficient, and flexible networks, these architectures face significant limitations. Virtualized RAN (vRAN) addresses these challenges by decoupling hardware from software, enabling dynamic resource allocation, centralized management, and cost savings through the use of Commercial-Off-The-Shelf (COTS) hardware. This paper provides a detailed comparison between traditional RAN and vRAN, examining their architectures, operational efficiencies, and implementation challenges. Real-world examples are presented to illustrate how vRAN transforms network deployment and management.

Keywords: Traditional RAN, vRAN, Radio Access Network, Virtualization, 5G, COTS, Centralized BBU.
