Since I do respect your knowledge of wireless technologies, what are
your thoughts on WiMax?  Does 802.16 indeed have any tangible benefits
over 802.11?  What about implementational differences?  Anyone have
anything promising?  The rags say WiMax is supposed to service people up
to 10 miles... but that's not really that informational, since the
record length for 802.11 is 86miles, and 30miles is already achievable
with a yagi.  Does the .16 have increased power so this 10 miles can be
using an omni?  The spectrum is higher so wouldn't it be more likely to
attenuate with weather (perhaps insignificantly)?

Thanks.

| | Well, I know that satellite is going to be slow and unreliable
| | (particularly in areas with heavy rains).
| |
| | What I would do:  do a line-of-site survey to see where I could see
| | (including, if I had to, from a 50' tower).  Get good signal put in
| | where I could see and buy a pair of good point-to-point radios in the
| | 5.8GHz range (something like the Wi-Lan Ultima3-ER radios).  These
| | radios can provide signal with the long range antennas up to 47 miles
| | (75 km) with good throughput (like 10Mb, same as ethernet).
| |
| | You can get good towers from Texas Towers (crankups if you don't want
| | to climb).  To do my 50' survey, I'd just hire a high-lift bucket
| | truck (here they run me $100/hr, probably a little more where you
| | are).
| |
| | Ultima3 radios will run about $2200 for each point on a
| | point-to-point, but are reliable (make sure you get good lightning
| | protection installed).
