Terrain-aware coverage

Per-node signal heat maps combine your chosen propagation model with Bullington / δ-Bullington (ITU-R P.526 / P.1812) diffraction over real elevation. Shadows and valleys behave like the real world, not a flat circle.

How coverage works

Link & path analysis

Per-link terrain profiles with Fresnel zones 1 & 2, the 60% clearance rule, earth-curvature correction, and multi-node paths rendered as one continuous cross-section.

Full link budget

FSPL or Okumura–Hata path loss, terrain diffraction, antenna gain, cable loss, receiver sensitivity and per-direction margins, plus optional vegetation loss from the land-cover layer using the Weissberger model.

Link budget & loss

Per-node antennas

Height, gain, 3 dB beamwidth, heading, front-to-back ratio, downtilt and measured MSI patterns. Each node is configured independently, with an on-map cone preview and tap-to-aim heading picker.
