Wireless Access Point

[agabriel-lg01uRcdP2Fg9hUCZPvPmw at public.gmane.org (Anthony Gabrielson)]

Well,
   I did end up going with something commercial, as I will be in a field and
need to get a reliable link between the two machines.  I don't think I'm
going to have time to work on this aspect for more than a few minutes as we
need to collect data in a short time period.  Work IT came up with network
express cards and they tell me they can provide them inside a week.  I'm
told that the field I will be in has cellular access so I'm crossing my
fingers it works.  If it doesn't I will just need more generators put in and
a trip to staples for several WAPs.

I appreciate the help.  My deciding factor was really the time required to
get in products and test them.  I had to write a non trivial amount of code
as it was to control the hardware that we will bringing with us, so I had
less time to hack on this.

Just in case I do need to fall back on plan B, what can I expect for range
in a field (good line of sight) from a typical WAP?  The weather conditions
will probably be extremely warm and humid, I guessing the heat index will be
at over 100F.

Thanks,
Anthony
