This latest feature enables field technicians to install and maintain fronthaul networks by testing connectivity and data integrity between the remote radio headend (RRH) and the baseband unit (BBU) on new fiber-fed cell towers. This enhanced CPRI functionality reduces the need for unnecessary tower climbs, thereby lowering maintenance costs and overall operating expenses (OPEX).
FTB-700G-w Legacy cell towers with copper cabling are being rapidly upgraded with fiber optic infrastructure. These new fiber-fed architectures offer flexibility and scalability, helping mobile network operators ensure service coverage and increase the capacity of their fronthaul radio access networks.
Alongside fiber, CPRI is playing a significant role in tower upgrades. CPRI is a new protocol that runs between the BBU and RRH, digitizing the incoming radio frequency signal over fiber. With CPRI, the base station no longer needs to be located directly next to the antenna on rooftops or other costly and inefficient locations. In contrast, the base station can be installed in locations where size, climate, and power availability are more easily managed.
Extended CPRI functionality is fully integrated into the NetBlazer FTB-700G and FTB-800 series handheld meters, with user-friendly interfaces. This greatly simplifies the work of field technicians for CPRI and fiber, as the test instruments have been designed and pre-configured to deliver comprehensive results with minimal training.
