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.

Topics

Site Viewer

Site Viewer basics, basemaps, and troubleshooting.

Troubleshooting Site Viewer

When you start Site Viewer up on showing a txsite or rxsite object, a check is made to make sure that you have an internet connection to retrieve the default basemap and terrain data.

Propagation Models

When to use the different propagation models based on frequency, type, and limitations.

Access Basemaps and Terrain in Site Viewer

To download MATLAB® basemaps:In addition, Site Viewer also supports three external basemaps that you can select from the basemap picker.
