The context of rising bandwidth and a drive towards cost-efficiency have forced mobile network operators (MNOs) to find new ways to increase competitivity while maintaining the quality of service that their customers have come to expect.
To achieve greater scalability, more capacity and longer-reach distances, MNOs across the globe are overhauling the traditional coaxial-based systems on their cell towers with fiber-optic cabling carrying CPRI protocol data.
Although these new fiber-based network architectures offer numerous benefits to MNOs, they also give rise to a new set of challenges, especially when it comes to troubleshooting issues at the cell tower and verifying the CPRI links between the remote radio head (RRH) and baseband unit (BBU). To do so effectively while avoiding costly interventions, cell technicians need to be well versed in various testing scenarios, and equipped with the right tools for the job.
