It was not my intention to co-op this thread into a conversation about
"do-it yourself wireless mesh networks", I only meant to support the OP
by pointing out potential uses for those frequencies - and also point
out that big business is -not- necessarily motivated to make the best
use of those frequencies.

I've just did some digging on google and there are abundant examples of
municipally funded and corporately funded wireless mesh networks.

We would need to wait for the cost of long-range high speed wireless
nodes to drop a great deal before there is even a chance of making the
'do it yourself' version of those networks.

The service providers (who might one day try to make it -illegal- to set
up a 'do it yourself wireless mesh network') are currently fighting
against the municipally funded networks.

So Fanta, when you hear about how much that municipal network costs -
you might ask whether the ISPs are funding that message. They would
-love- for the voters to overestimate the tax burden, as a municipal
network means less business for them.

Fanta, the military frequency ranges are not available on civilian
equipment. They have been testing signal generator systems that can set
off IED's before a vehicle even gets near it. Cell phones, garage door
openers, remote controlled doorbells, what have you, they are using
these types of devices to detonate IED's and a freq. gen. on each
vehicle would deter them is the theory I guess. Scary thought if you
ask me. What's to stop someone from placing an IED near a school? It
sure would suck to drive by and set one of those off..

There is a certain range that they have not used. They were reserved for
the defense department sometime after WWII. The military wasnt using
them because of the range. The reports of garage doors opening was near
an air force base.
I brought it up once, and my Instructer, an ex Navy man was talking
about the ranges being such that they didnt have a use for back then.
Newer digital technologies brought more interest in them. I could see it
for IED's, but this was near an Air Force base.
Still, I guess that could still be it.
Ill look for the article.

This is near a Marine Corps base. It says they are using them for
communication purposes.

It freezes the doors...

So much for the Stanley Co. hawking the security of their rolling code
technology!
