hello! experience with 802.11x and extreme humidity?

> As for why 2.4 GHz... 

1) The small wavelength at a frequency of 2.4GHz is small enough to allow a
   portable (PCMCIA sized) antenna.
2) At the time of design, 2.4GHz was the highest (ISM band) frequency which
   could be mass produced using CMOS technology.

One of the enabling technologies for WLAN was the development of cheap RF
systems operating a frequency high enough to allow a portable antenna.
As faster CMOS transistors become economic, frequencies will migrate to
5GHz (already happening) then 10GHz and so on through the ISM bands, probably
ending up at around 60GHz.

Advantages of the higher frequencies are:
1) Smaller antenna leading to smaller transceivers, or keep the antenna the
   same size but make it an adaptive array.
2) Decreased range - Allows more freqency reuse (hence more network capacity).
3) As mentioned by the previous poster, wider bands are allocated at higher
   frequencies.

Decreased range is not an advantage when you consider a a single user, but
when you consider the network as a whole it becomes an advantage, as total
network capacity is increased.
