RadioPropagation.jl

Julia package implementing radio propagation models.

The following is implemented:

• Two-Ray propagation model.
• Rain attenuation for frequencies in the range 1-400 GHz.
• Fog attenuation for frequencies above 5 GHz.
• Atmospheric attenuation for frequencies up to 1000 GHz.

Installation

The package can be installed with the Julia package manager. From the Julia REPL, type ] to enter the Pkg REPL mode and run:

pkg> add RadioPropagation

Or, equivalently, via the Pkg API:

julia> import Pkg; Pkg.add("RadioPropagation")

Examples

Two-Ray Propagation

Below is an example showing the two-way loss for two-ray propagation compared to that of free-space propagation. The code for the eample can be found in the function documentation.

Atmospheric attenuation

Atmospheric attenuation calculated as per [1].

using Plots

frequency_ghz = collect(1:1000);
attenuation_db_km = RadioPropagation.atmospheric_attenuation_db_per_km.( frequency_ghz );

plot1 = plot(   frequency_ghz, attenuation_db_km,
                xlabel  = "Frequency [GHz]",
                ylabel  = "One-way loss [dB/km]",
                title   = "Atmospheric Attenuation.",
                #ylims  = (),
                label   = "Standard",
                yaxis=:log,
                dpi=300
)

attenuation_db_km = RadioPropagation.atmospheric_attenuation_db_per_km.( frequency_ghz, 288.15, 0 );

plot!(  frequency_ghz, attenuation_db_km,
        label = "Dry air",
        yaxis=:log,
)
