Detailed Description

This class implements following formula:

pl = offset + distFactor * log10(distance * distNormFactor) + freqFactor * log10(frequency)

As in all Pathloss-models, minPathloss is guaranteed, so the returned value is max(minPathloss, pl).

offset, distFactor and freqFactor are configurable via pyconfig::Parser, distNormFactor is 1, if distanceUnit was set to "m", 1/1000, if it was "km".

You have to provide sensible values for validDistances and validFrequencies in your configuration. You can use whichever Pathloss model you like as out of range strategy (e.g. Constant, Deny, FreeSpace, another MultiSlope), but keep in mind that the pathloss will be discontinuous at the validDistances borders, if set up improperly.

Pathloss.py contains two example configurations, one sets up the Umts3003Outdoor model that was used in SGOOSE, the other sets up a free space model.
