Without coverage and capacity, mobile communication falters, and quality installation must be employed at mobile cell sites to ensure high performance. Macro towers and in-building DAS solutions require proper installation of antennas, cables, connectors, and other in-line components. The return loss and Passive Intermodulation (PIM) measurements are crucial techniques that verify quality installation of cellular networks. This course provides you with a technical understanding of various line sweeping measurements, including return loss, Voltage Standing Wave Ratio (VSWR), Distance-To-Fault (DTF), insertion loss, and PIM. The curriculum will provide step-by-step procedures for efficient cell site troubleshooting and an introduction to measurement units and required hardware for cell site technicians and tower climbers.
