Free Space Loss model

This model describes the theoretical minimum propagation path loss achievable in free space conditions. This model is appropriate to use on paths were unobstructed direct-Line-of-Sight propagation could be expected (e.g. point-to-point fixed service links, links over short distances in open areas, etc).

The Free Space Loss formula is applied by SEAMCAT as follows:

Note: The Free space model allows the possibility to include some variations in the similar manner as it is done for all other built-in models. If user wants to use just the median theoretical value, the variations option should be disabled.
