The aws says it means "Advanced Wireless Systems".
There are however only 13 question with this tag, and all except possibly two are written obviously thinking it's Amazon Web Services.
Option 3: Leave tag definitions alone, remove aws from questions related to Amazon Web Services.
Option 4: Do nothing.
I prefer options 1 and 2 (in that order). 3 seems unhelpful. 4 leaves a dozen questions apparently mis-tagged.
What think you all?
