Streaming multicast over wireless
In reference to this topic, we have been successful with multicasting over LWAPP. We are using Vocera and they require multicast for their broadcast groups. One key configuration step is to disable IGMP Snooping on the Vocera VLAN. Have you tried this for your application VLAN?

Re: [WIRELESS-LAN] LWAPP Client Communication...
We run over 100 medical applications, and moving from IOS WLAN to LWAPP hasn't caused any issues of this sort. Haven't heard of this before. Kevin Johnson, CCNA Cisco Wireless Specialist Health First Network Services 3300 Fiske Blvd. Rockledge, FL 32955 Phone 434-5557 Pager 634-7633 Cell 321-403-2542 >>> Justin Aharoni <[EMAIL PROTECTED]> 12/01/2006 11:35 AM >>> Happy Friday All: Gotta love the seemingly simple issues. So we have a Cisco LWAPP network all up and running, playing nice with just about everything. Ran into a problem this morning where a workstation management application couldn't talk to any of the client computers. The setup worked in the past when we used the regular 1230 AP's but since we've switched its decided to not work. Does anyone know if there is some kind of peer-to-peer client restriction that is configurable on the controller/WCS?

Re: [WIRELESS-LAN] using four channels instead of three
We experience and ran a 4-channel model for over a year. For data, 802.11b, not bad. But when you start adding voice and Cisco to the mix, who by the way doesn't approve of a 4-channel model (with documentation verifying this), you will run into issues. The perception thing will also get you into trouble from any vendor bringing in an application running across wireless.

Carder ( mailto:[EMAIL PROTECTED] ) To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Sent: Tuesday, January 02, 2007 10:44 AM Subject: Re: [WIRELESS-LAN] using four channels instead of three It was written: > 4 Simultaneous Channels Okay For 802.11b It's important to understand the differences of 3 channel vs 4 channel spacing for 802.11b vs 802.11g. Take a look at the transmit spectral mask shown in Figure 96 of IEEE 802.11 1999. At 11 MHz away from the frequency center you have to be down -30 dB, and at 22 MHz away from center you have to be down -50 dB. Here's a good document describing this for 802.11b and shows the differences in the xmit mask for 802.11g. Note that it is "easier" to get away with 4 channel spacing with b's CCK compared to g's OFDM. http://www.cisco.com/en/US/products/hw/wireless/ps430/ prod_technical_reference09186a00802846a2.html In a nutshell, 4 channel spacing is not really a problem for 'b', provided you're starting out with a low noise floor. If you're concerned about throughput on 802.11g, you may not want to use 4 channel spacing. Dale -- Dale W.

Re: [WIRELESS-LAN] Vendor Choice
We have been a Cisco shop for over 4 years. Not to take anything away from Aruba, but like vendor products always work well together. I am very pleased with our WLAN, both LWAPP and IOS solutions. Solid, stable, and reliable. Kevin Johnson, CCNA Network Engineer Cisco Wireless Specialist Health First NS&T 3300 Fiske Blvd. Rockledge, FL 32955 Phone 321-434-5557 Cell 321-403-2542 >>> Jay Howell <[EMAIL PROTECTED]> 10/19/2007 10:12 AM >>> I am in the process of evaluating vendors for a campus-wide rollout of wireless. I have narrowed my choices down to Cisco and Aruba. We are planning on creating three roles which are faculty/staff, student, and guest.Each of these roles will have varying degrees of access to systems on the network. Because of manpower issues we will be broadcasting the SSID and using Novell's LDAP to authenticate to the system. We are not a Cisco shop so there is no advantage either way as far as dropping into our existing system. My question is are there any gotchas I might be missing with these two vendors? From what I have seen, both systems seem to work nearly identically. You can access the same information from each controller, and both are self-healing when an AP goes out. Are there any support issues I should be aware of? We plan on making our decision around the first of November, so I look forward to any comments this group might have. -- * Jay Howell Executive Director of Information Technology Chowan University Ph: 252-398-6361 * ** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/. # This message is for the named person's use only.

Re: [WIRELESS-LAN] WiFi Location & Tracking
We have just rolled out Aeroscout RFID solution. I would be more than happy to discuss further details. One word of caution, your WLAN density will determine your accuracy in locating devices.

Every wireless device in the hospital building can be seen by at least three access points.
