Lee model for the region to the 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 so that the model flexible for different regions of propagation.
Contents
Applicable to / under conditions
This model is suitable for use on data collected in an area specific. The model predicts the behavior of all links that have extremes in specific areas.
Coverage
Frequency: 900 MHz Band
Formulation mathematics
The model
Lee's model is formally expressed as:
where,
L = average path loss. Unit: decibel (dB)
L0 = Loss of reference on the way over 1 km. Unit: decibel] (dB)
= The slope of the curve in the road loss. Unit: decibels per decade
d = distance at which the path loss is calculated.
AF = adjustment factor.
Calculation of the loss of path reference
The loss in the reference path is usually calculated over 1 or 1 km of liaison miles. Any other suitable length of the path can be chosen on the basis of the applications.
where,
GB = Base station antenna gain. Unit: decibels with respect to the isotropic antenna (dBi)
? = Wavelength. Unit: meter (m).
GM = Mobile station antenna gain. Unit: Decibel with respect to the isotropic antenna (dBi).
Calculation of adjustment factors
The adjustment factor is calculated as:
where,
FBH = Base station antenna height correction factor.
FBG = base station antenna correction gain factor.
FMH = Mobile station antenna high correction factor.
FMG = correction factor mobile station antenna gain.
FF = Frequency correction factor
The base station antenna height correction factor
where,
MP = height of the season antenna base. Unit: meter (m).
or
where,
MP = height of the base station antenna. Unit: feet (ft).
The base station correction factor of antenna gain
where,
GB = Base station antenna gain. Unit: decibels with respect to the half-wave dipole antenna (dBd)
The mobile phone antenna high correction factor:
where,
Hm = Mobile station antenna height. Unit: meter (m).
The gain factor of the mobile antenna correction
where,
GM = Mobile station antenna gain. Unit: Decibel with respect to the antenna half-wave dipole (DBD).
The frequency correction factor of
where,
f = frequency. Unit: megahertz (MHz)
