        Okumura-Hata Propagation Model
        The Okumura-Hata propagation model is a simple empirical model with short computation time.
        Extended Hata Model
        The Okumura-Hata model was extended to the frequency bands from 30 MHz to 3000 MHz¹. This combination is denoted as the Extended Hata model.
        Empirical Two-Ray Model
        The empirical two-ray model (ETR) model computes the path loss to each pixel based on the assumption that the direct ray and the ground-reflected ray would exist.
        ITU P.1546 Model
        This model is used for point-to-area radio propagation predictions for terrestrial services in the frequency range 30 MHz to 3 000 MHz.
        ITU-R P.525 & P.526 Model
        This propagation model combines the free space attenuation (ITU-R P.525) with the diffraction loss (ITU-R P.526) for any type of path as defined by a terrain profile.
        Deterministic Two Ray Model
        The deterministic two-ray (DTR) model computes the direct ray and the ground reflected ray with ray optical algorithms.
        Longley-Rice Model
        The Longley-Rice (or irregular terrain) model predicts long-term median transmission loss over irregular terrain relative to free-space transmission loss.
        Parabolic Equation (PE) Model
        The parabolic equations model employs numerical evaluation of the parabolic equation (PE) to compute the field strength in a macro-cellular area based on terrain data.
        Knife Edge Model
        This model takes the effect of the actual environment into account by using 3D vector building data (plus terrain profile).
        Rural Dominant Path Model
        The Dominant Path Model uses a full 3D approach for the path searching, which leads to realistic and accurate results.
        Rural Ray Tracing Model
        The rural ray-tracing model is a (deterministic) multipath propagation model, considering phenomena like multiple reflections and wave guiding effects in canyons is required to obtain accurate predictions of the signal level and the spatial channel impulse response.

      - Working with Rural Projects (Pixel Databases)
        Propagation of electromagnetic waves in areas with a low density of buildings depends mainly on the topography and the land usage (clutter). The vector data of the buildings must not be considered in such scenarios.
      - Working with Rural Projects (Vector Databases)
    - Urban
    - Indoor
      The phenomena which influence radio wave propagation can generally be described by four basic mechanisms: Reflection, diffraction, penetration and scattering. For the practical usage of propagation models in real scenarios these mechanisms must be described by approximations.

ITU-R P.525 & P.526 Model

This propagation model combines the free space attenuation (ITU-R P.525) with the diffraction loss (ITU-R P.526) for any type of path as defined by a terrain profile.

The computation of the diffraction loss is based on the modified Deygout method, but also makes use of the spherical Earth diffraction model. The method is fairly quick since only the diffraction loss is calculated. It is mostly useful in the UHF and above frequency range, where the influence of the surface of the earth in most cases can be neglected.
