For range 5925-7125 MHz (article 11.7), there are different rules for
APs, clients, and very low power devices. For APs (article 11.7.1),
the maximum EIRP is 30 dBm (article 11.7.1.1), and it's INDOOR-ONLY
(article 11.7.1.3); for clients of an indoor AP (article 11.7.2), the
maximum EIRP is 24 dBm (article 11.7.2.1), and it's INDOOR-ONLY
(article 11.7.2.3); for very low power devices (article 11.7.3), the
maximum EIRP is 17 dBm (article 11.7.3.1).
Thinking better about it, I might have miscalculated this one. Since the
smallest channel we use is 20 MHz, and the EIRP power density for
clients is limited to -1 dBm/MHz (article 11.7.2.2), if I'm doing the
calculations correctly the limit for clients would be 12 dBm, that is,
(5925 - 7125 @ 320), (12), NO-OUTDOOR
It's unfortunate that we cannot represent that kind of rule in db.txt,
and are forced to artificially limit the power by 12 dB (the full power
of 24 dBm I had calculated would work only for 320 MHz).
I would appreciate if you could look over these power density rules,
especially the ones which are in dBm/MHz instead of mW/MHz, since I
might have miscalculated something else.
And thinking even more about it, if I'm understanding article 11.7.10
correctly, a client can transmit only when associated to an AP, except
for the negotiation while joining the AP. I believe this corresponds to
NO-IR, so the correct line for that range would be:
(5925 - 7125 @ 320), (12), NO-OUTDOOR, NO-IR
