What is PWID control?

Hello community, Ițm new here.
I have a RAK v2 online for 3 months now. Anyway there are some things that I cannot understand and havent find anything online like documentation.
So in the specification of the device i found a table that intrigues me because nobody talks about this. Before the table there is this text:

The RAK Hotspot has an excellent transmitter performance. It is highly recommended to use an optimized configuration for the power level configuration, which is part of the HAL. This results in a mean RF output power level and current consumption.

In the table there are 3 columns: PA Control, PWID Control and Power.
What are all these word, what do they mean?
