In the particular frequency spectrum reserved for 802.x operations,
weather is not a contributing factor (unlike your DirectTV and
DirectWay satellite links which are affected), unless they've added a
frequency I don't know about.

I haven't looked too closely at the specifics of 802.16.  Supposed to
be faster (good).  What I look at are radio specifics.  Range (I'm now
using Wi-Lan radios in the UNII band -- 5.8GHz -- and they guarantee
connections using the correct antennas and good line of sight,
including a clear fresnel zone, of up to 47mi/75km), throughput, and
number of clients that can connect (approx 200).  Note that this is
almost certainly overkill for residential use (and incredibly
expensive, APs run over $3500.00 without the antenna, and clients over
$750 without the antenna).  I still use Proxim 2.4GHz equipment
(802.11b/g) for hotspots and at home.

Called:  right tool for the job.  So I care little about 802.x specs
(theory), but I do care about radio specs (implementation).
