Detailed Description

@ ITUPathloss chooses the LOS/NLOS pathloss and shadowing models according to a distance-dependent probability.

In ITU-R M.2135 (IMT.EVAL) pp. 31 the probability distributions for each scenario are given.

This class implements a semi-random probabilistic pathloss distribution by hashing the position of the two antennas and the distance between them. These hashes have random number properties and are then used to determine the LOS/NLOS model and the log-normal shadowing component.

Using hashes makes it possible to imlement the ITU-R models without any memory overhead. At the time of writing this model is able to calculate ~ 16250 pathloss values per second.

Usage:

This model is a base for all ITU-R specific pathloss for the ITU-R scenarios. The resulting models however, may all be used as any other RISE pathloss model.
