Re: [WIRELESS-LAN] Desktop projection to classroom display
Bruce, Actiontec's widi boxes can use 2.4 or 5. If you have a single band wifi NIC then it will piggy back on whatever you are currently connected as, 2.4 or 5. If you have a dual band card, then it can use the 2nd band for widi only. Works pretty darn good. Most of our teachers only use the widi now even though they have the option to hardwire via VGA or HDMI.

Re: [WIRELESS-LAN] Desktop projection to classroom display
It does but not directly. It also depends on the clients WiFi card. If it is dual channel card then one channel will be for WLAN and one channel will be for WiDi. But only the devices in the last year or two have dual channel cards. So most devices piggy back on the WLAN with their single channel cards. This can be a problem though if a client gets associated with a different access point in the middle of a WiDi session.

Re: [WIRELESS-LAN] Desktop projection to classroom display
Check out Actiontec Screenbeams. We use them in 30 of our classrooms and the wireless video stream is almost perfect. IT does require a good wireless network because WiDi piggy backs on your wireless routers. We use them in the classroom to wireless stream to our projectors.

Re: [WIRELESS-LAN] Using 4 channels rather then 3 for the 2.4ghz wifi
It is possible but not recommended. I would turn down the power on the APs so you have less bleeding. Could you stagger the APs so that you only use three channels, but have four APs? Just put the two APs on the same channel at opposite ends and turn down the power. Also I know for a fact that two Cisco APs can handle 100 users, all streaming audio. We have a Spanish exam that we do yearly that does this without any problems. So I would think if you had three that would be more than enough.

Re: [WIRELESS-LAN] 802.11n tied to 802.3at
You are correct about the 3750E, which are VERY , from Cisco. Cisco will be releasing another line of switches that fully supports this new PoE standard. I do know that if you get the Cisco 1252 access point with the b/g/n single radio, that a 3650 or 3750 will handle the power. What puts the power over the edge for the 1252 is when you have 2 or more radios in there. I heard this directly from a CCIE. The 1252 has the ability to have an A radio, B/G/N radio, and a N radio. If you have the B/G/N radio then y ou have 300mbps on the N radio. If you add the additional N radio it will bump up the speed to 600mbps.

Re: [WIRELESS-LAN] Airespace/Cisco, SNMP monitoring, CiscoWorks, etc.

In this model, without going directly to WCS and controllers, how are you getting info on AP status- can the controllers send effective traps for AP trouble?

Re: [WIRELESS-LAN] Cisco Self-Healing- does it work?
I do not use the self healing feature of my WLSE but I use several other things with it. I can change the code on any and all of my APs in a matter of minutes. Same with firmware upgrades. I can even schedule firmware upgrades to happen at midnight when everyone is gone and email me if anything goes wrong. If you have 50-100 APs then this helps out a ton. Also it has other features such as actual coverage of all of your buildings, with signal strength, overlap, speeds, etc. It can detect rogue APs. Adding in your building layout takes minutes if you already have the drawings in a digital format. It also has some AAA stuff build in. Great if you have WDS going. I prefer to have a good solid site survey before and after like someone has already mentioned and manually set the channels. I have heard that some people basically used the self healing as a plug and play type setup on the initial install and it was a mess. I really enjoy my WLSE but I have around 60 APs. Most are 1200s and a dozen or so 1100s. Once your WDS is setup, using the WLSE is very easy.

Re: [WIRELESS-LAN] Issue with RF collision Domains
Cisco has a new wireless system that uses a controller, much like MERU networks, that allows many APs in a small area. It basically turns 4 or 5 APS into 1 big AP that can handle high density situations like what you are describing. I have never used any of these but I know someone that does and has had good luck with them. You might want to look into something like that. Cisco APs can handle more than 40 clients per AP, although Cisco's recommendations are around 30ish. As long as each client isnt streaming video, you could probably get by fine with a couple of Cisco APs turned down to like 5% power. The 1200 APs are beasts.

Re: [WIRELESS-LAN] Administrative Wireless Network

In the past this administrative network was locked by static MAC addresses and a WEP key. I was wondering how different universities are handling this issue. (ex. WPA, static MAC addresses, 802.1x, etc.) This network will only be used by our IT staff, and the network has access to all university resources, based on firewall rules. Thanks for your help. Create a separate vlan. Put the admin team SSID on that new vlan. Use WPA or WPA2 encryption and you should be pretty secure. WPA2 you will want a radius server to use some of the EAP stuff but you can get by without one with WPA-PSK. Also setup your dhcp server to hand out ip addresses to that vlan. Then trunk all the connections that you want that vlan to have access too. Static MACs can be spoofed very easy, especially if you are only using WEP. Laptop with ethereal can break WEP encryption and find a valid MAC to use in less than an hour. There are even ways to make a access point send out tons of data, which allows the hacker to capture more packets in less time, which allows the WEP key to be discovered even quicker.
