Comms coverage
tr_comms_coverage
What it does
RF coverage from transmitter sites: received power with free-space loss and knife-edge diffraction, line of sight with 60% Fresnel clearance, best server, coverage and dead zones.
Like Radio frequency coverage workflow (Viewshed 2 + RF tools) in ArcGIS Pro and GRASS r.viewshed + Raster calculator in QGIS. Run by the product's terrain engine on 30 m cells from Copernicus DEM GLO-30 (full resolution): 740 x 930 = 688,200 cells; no model was called.
RF coverage from up to 3 dominant heights
3 site(s) cover 100.0% of the analyzed ground at -100 dBm; 58.8% has a 60% clear Fresnel zone.

Notes
- DEM: Copernicus DEM GLO-30 (open data; cached). Copernicus DEM GLO-30: produced using Copernicus WorldDEM-30 (c) DLR e.V. 2010-2014 and (c) Airbus Defence and Space GmbH 2014-2018 provided under COPERNICUS by the European Union and ESA
- sites: on the dominant heights DH-1 (2,456 m), DH-2 (2,080 m), DH-3 (2,046 m)
- the grid (30 m) is finer than the DEM (30.9 m): values between DEM samples are interpolated
- bare earth: clutter, buildings, vegetation, antenna patterns and multipath are not modeled
- paths evaluated every 2 cells and filled to the nearest evaluated cell
