The ITU terrestrial model for one terminal in woodland is a radio propagation model belonging to the class of foliage models. This model is a successor of the early ITU model.
Contents
Applicable to/under conditions
Applicable to the scenario where one terminal of a link is inside foliage and the other end is free.
Coverage
Frequency: below 5 GHz
Depth of foliage: unspecified
Mathematical formulation
The mathematical formulation of the model is:
Where,
Av = Attenuation due to vegetation. Unit: decibel (dB)
A = Maximum attenuation for one terminal caused by a certain foliage. Unit: decibel (dB)
d = Depth of Foliage along the path. Unit: Meter(m)
Points to note
The value of
The model assumes that exactly one of the terminals is located inside some forest or plantation and the term depth applies to the distance from the terminal inside the plantation to the end of plantation along the link.
