RE: Wireless Bridge Recommendations
We use Ubiquiti for the small stuff like single cameras or special events and use BridgeWave for the hard to get to buildings or as a backup connection.

Initially, we built out a large two story office area that has a fixed connection back to our main campus. Networking within the same building was simple as we did this during the renovation. With our growth, the administration is now planning on throwing together another Ad Hoc office space in a separate building. This building is relatively close to our main office space (+-50 feet), however we have no cabling between buildings and no conduits in place. I'm interested in testing out a low latency line of site wireless bridge, one that I could utilize to distribute to multiple buildings as our growth continues, across up to 1000 feet and from 100-1000mbps speeds. Can you share what vendors you've had success with? Engenius, Ubiquiti, etc., come to mind initially.

RE: Rogue Devices
We use Prime Infrastructure and MSE. With Prime, if you add both APs and switches, you can shut off wired port to disconnect rogue, but you still have the RF interference to deal with. Works pretty good other than all the issues with Prime, but as a whole, this solution works. Just wish we had resources to go after all the rogues . . . they are everywhere.

RE: [WIRELESS-LAN] Channel Utilization
Thanks for the feedback John. I felt that 34% was too low and I’m working with our Cisco wireless SE to get more clarification. If I remember correctly, back in the days of shard Ethernet, we used to use 50% as the measuring stick for a network that was getting congested and at 70-80% you were in the tank. Anyone have any links or data that show the impact of channel utilization.

I'm not sure where the 34% number came from, but it matches with the maximum practical utilization of the Aloha network in the late 60's. Perhaps it is entirely a coincidence that Aloha and 802.11* show similar maximum utilization? I'd love to see graphs of throughput vs. utilization for various protocols, but can't lay my hands on any at the moment.
