A test device tests conditions associated with a fronthaul in an Open Radio Access Network (O-RAN). The test device can field test an O-RAN radio unit (O-RU) installed at a cell site by emulating an O-RAN distributed unit (O-DU) in the O-RAN connected to the O-RU via the fronthaul of the O-RAN. The testing includes testing connectivity of the O-RU to the fronthaul. The testing includes executing managing plane (M-plane) and synchronization plane (S-plane) messaging to test management session establishment, device setting testing, and master clock synchronization testing. Additionally, optical insertion loss in the fronthaul and frequency and power of signals transmitted from the O-RU can be tested.

Test device with distributed unit emulation for testing in open radio access network

Systems, apparatuses, and methods for implementing a real-time Open Radio Access Network (O-RAN) fronthaul analyzer and graphical user interface (FHA/GUI) are provided. In one example, a method describes receiving an O-RAN fronthaul (OFH) packet traffic flow; parsing packet headers of the OFH packet traffic flow; identifying and tracking active flows in the OFH packet traffic flow using the parsing; and presenting a visual representation of the active flows using the tracking of active flows. In some examples, the real-time O-RAN FHA/GUI may be used for testing an OFH link for compliance with the O-RAN standards.

Real-time O-RAN fronthaul analyzer and graphical user interface

A cell site test tool provides field technicians with resources to support multiple aspects of cell site testing. The cell site test tool includes multiple, integrated and removably connectable modules such as a base module, a user interface module, and a battery module. Additional modules include a CPRI module to provide Common Public Radio Interface testing, an OTDR module to provide dedicated Optical Time-Domain Reflectometer testing, a CAA module to provide Cable Antenna Analysis testing, a fiber inspection module to visually inspect optical fiber, and an SA/CPRI module to provide Radio Frequency over Common Public Radio Interface testing.
