Area-to-area Lee model

The Lee model for area-to-area mode is a radio propagation model that operates around 900 MHz. Built as two different modes, this model includes an adjustment factor that can be adjusted to make the model more flexible to different regions of propagation.
Applicable to/under conditions.
This model is suitable for using in data collected. The model predicts the behaviour of all links that has ends in specific areas.

Frequency: 900 MHz band
Mathematical formulation.
The model.
The Lee model is formally expressed as:
formula_1
where,
Calculation of reference path loss.
The reference path loss is usually computed along a 1 km or 1 mile link. Any other suitable length of path can be chosen based on the applications.
formula_3
where,
Calculation of adjustment factors.
The adjustment factor is calculated as:
formula_5
where,
Base-station antenna height correction factor.
formula_6
where,
"or"
formula_7
where,
Base-station antenna gain correction factor.
formula_8
where,
Mobile-station antenna height correction factor.
formula_9
where,
Mobile-antenna gain correction factor.
formula_10
where,
Frequency correction factor.
formula_11
