Course Overview

Coverage and capacity are extremely important for mobile communication and they are tightly coupled with quality installation of hardware components at cell sites. Both macro towers and in-building DAS solutions require proper installation of antennas, cables, connectors, and other in-line components. Return Loss and Passive InterModulation (PIM) measurements are crucial techniques to check quality installation of cellular networks. This course provides a technical understanding of various line sweeping measurements including Return Loss, VSWR, Distance-to-Fault (DTF), Insertion Loss, and PIM. The course covers fundamentals, step-by-step procedures for efficient cell site troubleshooting and introduction of measurement units and required hardware for cell site technician and tower climbers. Hands-on exercises using industry approved measurement units towards the end of the course help understand current field practices using effective line sweeping tools.

Intended Audiences

  • Field Technicians, RF Engineers, Tower Technicians and Foreman.
  • Equipment Engineers
  • Decision-makers and operations personnel
  • Members of Operations’ team who are involved in troubleshooting, In-Building DAS Installers, Design-ers and Project Managers
