Hi Jeff,
I haven't seen you on a.i.w all that much lately, but, I knew
you frequented s.e.r more studiously, so, I'm very glad you
stopped by to help us out.

All we want to do is nail down the iPad WiFi specs.

There is speculation that they are substandard (as compared to
similar non-Apple equipment); but let's leave that speculation
out of the factual data for now, and just figure out what it is.

I have a question about what those numbers in the quote are for.

If the transmit "output" is 16dBm at 2.4GHz and 17dBm at 5GHz,
I presume you mean sans an antenna because I don't see the
customary 3dB difference between the two numbers (which would
be entirely antenna related).

If so, the radio transmit power is roughly 40mW at 2.4GHz.
And, at 5GHz, it's roughly 50Mw.

Are my assumptions above about nominal transmit power correct?
