Curious if anyone has any feedback on firetide's mesh routers? thanks. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Nigel Ballard Sent: Tuesday, July 16, 2002 4:24 PM To: [EMAIL PROTECTED] Subject: [BAWUG] canopy
Canopy doesn't mesh. They certainly play down the LOS aspect which is very real in this instance. You need a high and clear mast, building roof is better. The Canopy solution has expandability, robustness and security all engineered in, and as such, is one viable alternative to 802.11b. And for short range <2Mile LOS building to building secure hops, it is a slam dunk.

Okay, so if the access points don't need a backhaul, they > gotta retransmit from other access points, right? It's a nested star arrangement from what I can see: you home the users on a "ecll site"; 1 or more reecivers on mid-band for the customers; then a backhaul radio on hi-band (do I have the segments right?) up to 20 miles with 2 dishes to your hub. Multiple hubs could probably combine to other backhaul radios to your NOC. I presume you'd want to avoid wires entirely if you could.

Guess so. :-) Cheers, -- jra -- Jay R.
