Course Overview

This course will provide participants with a comprehensive introduction to the many fundamental concepts that drive the design and performance of an In-building communications system. This module will provide a review of the physics, mathematical, and communication system principals that are fundamental to implementing In-building wireless initiatives, beginning with coverage of how cellular radio signals propagate indoors through clutter with the goal of being able to determine the density of antennas and RF power levels necessary to achieve the service objectives for the subscriber community.

Intended Audiences

  • In-building technologists
  • DAS equipment manufacturers and test equipment manufacturers
  • Personnel who desire to refresh and advance their understanding of In-building technical concepts
