RF Propagation

Site and terrain visualization, propagation model specification, communication links, signal strength, signal coverage maps, Longely-Rice

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.

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.

Access Basemaps and Terrain in Site Viewer

You need an active internet connection for all basemaps except Dark Water.
