MATLAB/Octave Implementation of Recommendation ITU-R P.1411 (Site-General Prediction Methods)

This code repository contains a MATLAB/Octave software implementation of site-general prediction methods in Recommendation ITU-R P.1411-11 §4.1.1, §4.2.1 and §4.3.1 with propagation data and prediction methods for the planning of short-range outdoor radiocommunication systems and radio local area networks in the frequency range 300 MHz to 100 GHz.

The following table describes the structure of the folder ./matlab/ containing the MATLAB/Octave implementation of Recommendation ITU-R P.1411.

File/Folder Description
tl_p1411_belowroof.m ITU-R P.1411 §4.1.1
tl_p1411_aboveroof.m ITU-R P.1411 §4.2.1
tl_p1411_lowheight.m ITU-R P.1411 §4.3.1

§4.1.1: Site-general model where both the Tx and Rx stations are located below-rooftop regardless of their antenna heights

L = tl_p1411_belowroof(f, d, type, var)

Required input arguments of function tl_p1411_belowroof

Variable Type Units Limits Description
f double GHz See Note Frequency
d double m See Note 3D direct distance between Tx and Rx stations
type int 1 - LoS, Urban (high-rise, low-rise)/Suburban, 2 - NLoS, Urban high-rise, 3 - NLoS, Urban low-rise/Suburban, 4 - NLoS, Residential Envirnonment type
var boolean Set to true if variations are to be computed in Monte-Carlo analysis

Note

URBAN: LoS, Urban (high-rise, low-rise)/Suburban
f = 0.8 - 82 GHz, d = 5 - 660 m
HIGH_RISE_URBAN: NLoS, Urban high-rise
f = 0.8 - 82 GHz, d = 30 - 715 m
SUBURBAN: NLoS, Urban low-rise/Suburban
f = 10 - 73 GHz, d = 30 - 250 m
RESIDENTIAL: NLoS, Residential
f = 0.8 - 73 GHz, d = 30 - 170 m

§4.2.1: Site-general model where one of the stations is located below-rooftop, and the other above-rooftop regardless of their antenna heights

L = tl_p1411_aboveroof(f, d, type, var)

Required input arguments of function tl_p1411_aboveroof

Variable Type Units Limits Description
f double GHz See Note Frequency
d double m See Note 3D direct distance between Tx and Rx stations
type int 1 - LoS, Urban high-rise, Urban low-rise/Suburban, 2 - NLoS, Urban high-rise Envirnonment type
var boolean Set to true if variations are to be computed in Monte-Carlo analysis

Note

URBAN: LoS, Urban high-rise, Urban low-rise/Suburban
f = 2.2 - 73GHz, d = 55 - 1200 m
HIGH_RISE_URBAN: NLoS, Urban high-rise
f = 2.2 - 66.5 GHz, d = 260 - 1200 m

§4.3.1: Site-general model for terminals of low hight from below roof-top to near street level (1.9 m < h < 3 m).

L = tl_p1411_lowheight(f, d, type, p)

Required input arguments of function tl_p1411_lowheight

Variable Type Units Limits Description
f double MHz 300 ≤ f ≤ 3000 Frequency
d double m 0 < d ≤ 3000 3D direct distance between Tx and Rx stations
type int 1 - Suburban, 2 - Urban, 3 - Dense urban/high-rise Envirnonment type
p double % 0 < p < 100 Location percentage

Optional input argument of function tl_p1411_lowheight

Variable Type Units Limits Description
w double m transition region width between LoS and NLoS (typical w = 20 m)

Output

Variable Type Units Description
L double dB Basic transmission loss
