Java Implementation of ITU-R M.2135-1 Propagation Model

This code repository contains a Java software implementation of path loss model from Report ITU-R M.2135-1 (Tables A1-2 and A1-3). Note that only outdoor scenarios UMa (urban macro), SMa (suburban macro), and RMa (rural macro) are implemented in this version. The model supports LoS and NLoS propagation conditions as well as the LoS probabilities.

This version of the code is also implemented in SEAMCAT.

The following table describes the structure of the folder ./src/ containing the Java implementation of the M.2135 model.

File/Folder	Description
main/M2135.java	Java class implementing WINNER II propagation model
test/M2135Test.java	Java class implementing validation tests

Function call

L = tl_m2135(f, d, h1, h2, W, h, env, lostype, variations);
