Nobody makes a home access point that cranks out 1 watt (+30dBm).
Inside the access point is the same PCMCIA card that's used in the
laptop.  1 watt would be exessive power and an "alligator" (big mouth,
small ears).  

The assumption with wireless is that the transmit and receive range of
each radio is similar.  If you increase the transmit power of the
access point, it would NOT impove the range unless the power of the
laptop PCMCIA card were increased the same amount.  The range is
limited by the access points ability to hear the laptop transmitter,
who's power is only about +15dBm.

There are also some rules (15.247)(?) about increasing the power level
which limit the antenna gain that can be used.
