I don't really have any experience in the particulars, but I believe
the coverage classes exist for that:
$ iw phy0 set distance
Usage: iw [options] phy <phyname> set distance <distance>
Set appropriate coverage class for given link distance in meters.
Valid values: 0 - 114750
or:
$ iw phy0 set coverage
Usage: iw [options] phy <phyname> set coverage <coverage class>
Set coverage class (1 for every 3 usec of air propagation time).
Valid values: 0 - 255.
