Re: [WIRELESS-LAN] Implementing VOCERA with Cisco Wireless and Cisco Call Manager
Hey Michael - I did this many years ago and have helped tune these for hospitals recently. I am assuming you are talking about badges and not just the smartphone integration. You do need a very robust WiFi coverage to support Vocera - 5Ghz is the way to go. The real tuning is done at the badge configuration - Vocera allows you to tune the roaming characteristics of the badges so that they only scan for the channels you are using. Vocera is really good about helping you tune - in fact they are pretty demanding and won't take your word for it - they want to verify or run the configs they know work.

Re: [WIRELESS-LAN] [EXT] [WIRELESS-LAN] Wi-Fi in the Elevator Car
I have designed and deployed in car WiFi for a few folks - one we had a Cat 5 cable that was part of the traveler cable (so certified from a movement perspective) and the other we had a pair that I used a DSL converter on to get a few MB of traffic for the AP. These were all 10+ story buildings. The AP channel was fixed and discrete from the ones used on each floor - each car in the bank used the same channel and power setup - rarely did the cars stay on the same floor except in the late evening - Signal was basically blocked in the shaft anyway other than when the doors opened. Results were pretty good for the times and good enough to keep a VoIP call going in optimal situations (excluding client generated issues) We looked at P2P from the top of the shaft, but then I visited the top of one of the shafts and realized the dust and grease and access issues made it a non-starter.

Re: [WIRELESS-LAN] Cisco Wireless Controller Feature Gaps
We've been using this (VLAN Pooling) at Brandeis for the same time period and have been very happy with it. One new feature in Aruba OS 5.0 is the ability to have an SSID on any AP (no special provisioning) act in a bridge mode while also maintaining the 802.1x security and any firewall rules that tunneled VAPs have. They market this for branch offices, so users can use the same SSID's and have the same security while dropping them on a local net. We are using this to drop desktop clients on local VLAN segments so they can act like regular desktops. We also have a static IP reservation system for building subnets, so this help as well.

Basically, you create a pool and put as many or as few VLANs you want in that pool. You can even add VLANs as needed. The VLAN pool is tied to an SSID for a group of APs and it acts just like a single VLAN for configuration purposes. The controller load balances users across the VLANs in the pool (by MAC address hash, I believe). This allows us to have may subnets associated with an SSID and automagically spread users across those nets. It works extremely well. I no longer worry about running out of wireless client IP addresses. If the pools start showing higher usage, I just add another VLAN to the pool. That way we keep our subnet sizes down (class Cs), but can support thousands of users on wireless network without having enormous broadcast domains. Aruba’s IP mobility takes care of clients roaming between APs on different controllers. This feature is one of the best that Aruba has come out with. It makes wireless network planning and scaling easy.

Re: [WIRELESS-LAN] Streaming multicast over wireless
We are doing the same thing here at Brandeis. We have Video Furnace and we chose to only stream it over the a network for congestion reasons. If you have a G only network you could do the same thing. In fact you are probably correct that most clients are BG. I should pull a report from our system that will tell us. The comfit on our Aruba system was quite simple to set up multicast. Since you already have your core routers set up for multicast then you are 90% there. http://www.arubanetworks.com/news/release/2006/10/16 http://www.videofurnace.com/success/success.php --- John W.

One good thing we did was to disable the lowest connection rates across all protocols. In our test it wasn't so much a function as number of users, as all 4 channels were essentially broadcast (first generation lightweight APs .. multicast is effectively broadcast). Recently lightweight models for multicast are much better at controlling traffic, but at 2Mbps I doubt you could get too many channels going without affecting the data traffic. Better QoS controls could help though. So I'd say it's good for the press release but at a decent resolution it's going to be difficult to support more than a few channels. -Kevin Chris Hart wrote: I am working on testing streaming multicast video over wireless and wanted to find what others have found in their testing/deployment.

Each channel is currently a 2 Mbps stream. I am starting to test the system over the wireless network. I wanted to see if other schools had done similar testing yet. The first question I am trying to answer is how many users per AP? The second is will this work with 802.11g (not allowing 802.11b speeds). As most of our users still have 802.11b/g radios? The third is what is the implications of adding wireless VOIP sometime soon? Our current infrastructure is Cisco 1200's using a WLSM/WLSE solution.

Re: [WIRELESS-LAN] WPA or VPN
We have 2 SSID's one that is open but blocks most insecure protocols i.e. anything that would expose your university email and password. And a secure WPA2 network that authenticates against our AD (students and Staff) Basically if you can't do WPA2 then why bother trying to make something work WPA is good but not something I'd like to rely on. Running mixed mode WPA/2 is like not running WPA2 at all so why bother? We do offer our Juniper SSL VPN to our open network users. It is configured to auto launch the net connect client and split tunnel only the protocols we want to carry. It also times users out at 2 hours. Any one using WEP is actually doing a disservice to their community as it is providing a false sense of security as the protocol has been officially killed: http://www.cs.ucl.ac.uk/staff/M.Handley/papers/fragmentation.pdf We have a lot of users on WPA2. We provide instructions and a configurator to our users. Though I must say really most people use the insecure wireless as it does all they need. --- John W.
