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.Coverage
Frequency: 900 MHz bandMathematical formulation
The model
The Lee model is formally expressed as: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.where,
Calculation of adjustment factors
The adjustment factor is calculated as:where,
