The mean path loss is characterised by a dual-slope model with a break point d_BP, an exponent of 2 for all distances less than d_BP, and an exponent of 3.5 otherwise. In short, the mean path loss, L, in dB is

...

The log-normal distributed shadowing with the corresponding standard deviations deviation is applied to the pathloss calculated.

This propagation model is used to calculate terminal-terminal interference and takes account of shadowing losses due to objects between the two terminals, but does not explicitly account for any loss from near-field objects, such as the person carrying the equipment.
