The mention of ETSI EN 300 328 in item 55 (a) leads me to believe that
this is the limit we should be using, i.e. 500 mW. It is a bit confusing
though since it seems like such devices would also fall under "digital
modulation transmitters."

This looks correct.

Since this range requires TPC we need to set the power limit at 100 mW.

These ranges also require TPC so we need to set the limit at 500 mW.

In the document the ranges are 5650-5725 MHz and 5725-5850 MHz. I
suspect that the existing rules fudge that to line up with the wifi
channels, which technically is okay because the rules in the former
range are more restrictive. I wonder if we shouldn't be recording them
here as per the document and adding AUTO-BW. Johannes, any thoughts?

This looks correct.

Thanks,
