The switch I am looking to replace is at my core, tying my APs together, and to the main router. The one I am looking at/leaning to is the Dell Powerconnect 2708. Its Web manageable, and has some pretty impressive features, including broadcast storm control VLan tagging, and port mirroring.

BTW, this is what gets lots of people in trouble. Quoting 16-18 mesh nodes per square mile may be a correct number in AZ or TX. You may need 3 times that in my neck of the woods here in NE USA. Even more where interference shrinks cell sizes. Be cautious John. Brad -Original Message-

Here in Atlanta, Metrocom reported that it took 4 times the average number of nodes to provide coverage. Technology has changed a good deal since then, but then again they were also using 900Mhz, which has a lot more success with our pine trees than 2.4Ghz. -Matt Brad Larson wrote: BTW,

I haven't read your summary yet, but would like to chime in a bit on Mesh... When the DoD developed TCP/IP, they built it to be robust under war-time conditions. This means fault tolerant, rerouting, change-over, change-back. It would wonderful to hear the Mesh scientists (not sales people)

The internet is the largest mesh network in operation today. However, there is no comparison to internet routing and redundancy to that of private network routing and redundancy. The internet is so huge that smart routing decisions can only be made at the edge. With a private network, the size

I used street pricing for the radios in question, but certainly didn't cover pricing on any other items that would be required. Coverage area wasn't taken into consideration as it has no bearing on topology. -Matt Dawn wrote: Matt, Are these actual costs? What is the coverage area? Thanks,

There is a very big difference from fiber mesh and wireless mesh. Wireless is classicly a bunch of HDX links where fiber is PtP links. Your example doesnt make it clear that the difference is what cause's 802.11[a|b|g] mesh suck and fiber/copper mesh's not suck. The solution is multi radio

My example used wireless P2P links, which has no inherent weakness over fiber P2P links from a topology point-of-view. It would appear you are falling into the same trap as others by forcing mesh to be something it is not. Mesh is just a network topology; no more, no less. Sure it is possible
