RF Propagation

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.
