Abstract
A test device can be used with an Open Radio Access Network (O-RAN) fronthaul and to test an uplink communication channel. The test device determines an uplink communication channel for passive intermodulation distortion (PIM) testing. The test device generates and transmits control plane (C-plane) messages to request the future RBs from an O-RAN radio unit (O-RU) installed at a cell site according to a delay time period. The test device receives user plane (U-Plane) messages from the O-RU containing data for the future RBs, and determines whether PIM is detected.
