At the beginning necessary geometry parameters are calculated, based on input parameters. Then, depending on the range in which the transceiver and receiver are, ITM model computes a reference attenuation Aref – the median attenuation relative to a free space. The reference attenuation is a function of distance d, what is illustrated below. The cumulative attenuation comprises reference attenuation and attenuation of quantiles A(qT, qL, qs) – which are calculated based on normal distribution, as variability of time, localization and reliability.
