Longley-Rice propagation model is also known as the Irregular Terrain Model (ITM) added in this update. RadioPlanner 2.1 uses version 1.2.2 of the Irregular Terrain Model in PTP-mode. This propagation model is considered the industry standard for calculating radio coverage in North America.
The implementation of the Longley-Rice model and FCC contours calculation in RadioPlanner 2.1 was carefully tested and verified using L-R TV stations coverage from the website www.rabbitears.info. See screenshots.
For TV and radio broadcasting projects only, for mobile coming soon.
