usage means here?

usage means here?

Want usage? See usage. Have usage. But you are not saying what usage are you looking for.
i theory means some thing like air time utilization but is very imprecise
in 2.4ghz wifi devices like (rb951) i have compared the readings of this utility in contrast to a known spectrum analyzer and i have very different readings
when he says “14.3” you’re saying?
thank you very much for this great clear my incognita.
