site and terrain visualization, propagation model specification and visualization, path loss, tirem™, longley-rice, outdoor and indoor ray tracing

rf propagation describes the behavior of electromagnetic radiation from a point of transmission as it travels through the surrounding environment. the analysis of rf propagation is essential in understanding how electromagnetic waves incur losses from a transmitter to a receiver in different scenarios. you can use propagation models to calculate the coverage, sinr, signal strength, path loss, and link loss between a transmitter and a receiver in basic, urban, terrain, and multipath environments.
