This case study explains how CellAdvisor simplifies antenna isolation testing to quickly identify radio link issues in modern C‑RAN deployments. In C‑RAN architectures, radio units are installed remotely on towers or walls while baseband units are centralized in baseband hotels, connected by fiber links that can span tens of kilometers. This separation reduces capital costs and supports higher data rates, but also makes it harder to locate isolation problems. CellAdvisor provides fast, accurate testing to detect interference or coupling between antennas, helping technicians maintain reliable performance in evolving radio access networks.
