:1Watt? thats quite a bit of power, not quite what the FCC quite had in

FCC 15.247
(b) The maximum peak output power of the intentional radiator shall
not exceed the following:
(1) For frequency hopping systems in the 2400-2483.5 MHz band
employing at least 75 hopping channels, all frequency hopping systems in
the 5725-5850 MHz band, and all direct sequence systems: 1 watt. For all
other frequency hopping systems in the 2400-2483.5 MHz band: 0.125
watts.
(3) Except as shown in paragraphs (b)(3) (i), (ii) and (iii) of this
section, if transmitting antennas of directional gain greater than 6 dBi
are used the peak output power from the intentional radiator shall be
reduced below the stated values in paragraphs (b)(1) or (b)(2) of this
section, as appropriate, by the amount in dB that the directional gain
of the antenna exceeds 6 dBi.
(i) Systems operating in the 2400-2483.5 MHz band that are used
exclusively for fixed, point-to-point operations may employ transmitting
antennas with directional gain greater than 6 dBi provided the maximum
peak output power of the intentional radiator is reduced by 1 dB for
every 3 dB that the directional gain of the antenna exceeds 6 dBi.
[This table was useful!

Note that 6 dBi on 1 Watt output gives 4 Watts EIRP.
Also note that if the link is point to point, then there is no limit
to the EIRP -- e.g., if you were to drop 10 dBi in transmitting power, you
could increase the directional gain by 30 dBi to a total of 36 dBi.
Or so I read it.
