My thoughts (not speaking for my employer) are right along the same lines.

RE: Alternatives to Bonjour
A number of no-name vendors as well as Crestron, InFocus etc. have devices that you attach to a TV or projector. They display the device’s name/IP/and a rolling code. All the ones we’ve tried need a proprietary client – typically you browse to the name/IP shown to download it – which you then use to connect to the IP or name of the device, enter the code as the password, and you can share your screen. Some have four-way Hollywood squares etc. Some of these devices are wireless with the usual caveats (can’t do WPA2/EAP), but typically you can disable wireless, and some devices are wired only, so your clients use the existing wireless infrastructure without mDNS/Bonjour. The price varies widely from $100-$1999, and none of the devices we’ve demoed seem quite fully baked yet, and there’s a lot of “oh, the IOS/Android client isn’t quite done yet” vaporware. Also, the video quality for showing real video instead of just powerpoint varies a lot. And then you have stuff like Barco Clickshare which combines the worst of both worlds. It doesn’t use Bonjour, but instead must be set up as its own AP. -- Toivo Voll Network Engineer Information Technology Communications University of South Florida From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU] On Behalf Of Chanowski, John Sent: Wednesday, August 28, 2013 1:19 PM To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Subject: [WIRELESS-LAN] Alternatives to Bonjour Does anyone know of an apparatus/application that allows mirroring/streaming to a TV screen wirelessly that does not depend on Bonjour or equivalent protocols and instead relies on more enterprise friendly protocols?

RE: RF interference from 802.11
Putting on my ex-physicist hat for a moment... Without knowing what the experiment is and how it and its room are shielded, it's hard to tell. That being said, giving the concerned faculty member the specs (power level, gain, frequencies) and offering to reduce the power or turn off one of the radios, or do a Let's try it out, and we'll turn it off if it does interfere? offer might work. It might also help to explain that enterprise Wi-Fi devices are pretty clean and do typically not radiate appreciably outside of their intended frequencies. Give them all the technical data necessary for them to make the judgment, and do it with some olive branches to avoid the impression that IT is running over the needs or desires of faculty but rather wants to work with them. Considering that cordless phones and microwave ovens among others will cause just as much if not more interference on 2.4 GHz than a Wi-Fi AP, it seems to me that unless their surroundings have been specifically sanitized you'd not be introducing anything new, which could also be a point to make.

RE: [WIRELESS-LAN] Wireless in Residence Halls
Our experience matches that of a lot of other schools. Initially, for budget reasons, a few buildings got APs in the hallways, but that's a suboptimal RF design and will not work properly, and we quickly moved away from that and instead tackled the hassles of trying to get APs into rooms and suites. This also made for natural small cells, which are pretty important. Things like NetFlix and Hulu are popular uses of the network, and when streamed over wireless, you have to start limiting users per AP. The additional benefit of putting the APs in non-public areas to us as well was accountability, so that if damage were to occur, housing could bill the residents. Luckily, we also have not seen notable loss or damage. We use Cisco APs and small locks to affix them to their brackets, but no protective coverings beyond that. The Cisco brackets also make the cables inaccessible, so we haven't dealt with students unplugging anything*. We and our residence staff were concerned about vandalism initially, but everyone has been pleasantly surprised. In some of our new buildings each suite has a small mechanical closet for water heaters etc. and that turned out to be a good place for the AP, as it's reachable from the hallway and not reachable by the residents, but still basically in the suite. If there's new construction or renovation, doesn't hurt to have a chat with the architect or engineer to see if they have any ideas. The biggest complaint we have received regarding the access points in rooms was that the blinking light bothered residents, so in the residence halls we've turned off the LED indicators. Also, 5 GHz is a must. There's no way to get 2.4 GHz to work reliably, the lack of channels for tiling and microwaves, game controllers and other endless amounts of 2.4 GHz devices see to that, and we strongly encourage students to get dual-band cards or systems. In buildings where we have blanket wireless coverage, the use of wired connections by residents has almost completely vanished even when there's a hot and ready jack right in their room, so there's an obvious strong preference of wireless among the student population. This can maybe be translated into a cost savings to justify the Wifi install. -- Toivo Voll Network Engineer Information Technology Communications University of South Florida *In some of our older classrooms where we rigged wireless using existing jacks that were accessible, we repeatedly had to go and plug them back in because people would ignore any amount of don't unplug / don't touch signage or common sense. Based on that experience, if your jacks / AP jacks are accessible, I'd certainly recommend some kind of enclosure that keeps enterprising self-help fingers off them. -Original Message- From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU] On Behalf Of David Robertson Sent: Wednesday, December 19, 2012 8:37 AM To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Subject: [WIRELESS-LAN] Wireless in Residence Halls We are looking at how we install wireless in our Residence Halls for coverage.

RE: wireless as network standard?
That has been one of our concerns as well. People increasingly (due to some internal budget / property accounting rule changes) are getting laptops and devices they can take off-campus, and our desktop management group has been starting to look at solutions which “phone home” for patches and upgrades and inventory control – those would at least somewhat ameliorate the lack of WoL. Residence halls are almost all wireless, even if wired is available. Faculty and staff offices are still all wired to PCs. Imaging and backups and all the virtualized applications and cloud based computing works better when users are on Gigabit instead of contending for airtime, but this of course again depends heavily on your users.

RE: gaming consoles
A couple of observations, in no order of importance: -Getting people to buy the dual-band wireless adapters, instead of 2.4 GHz –only ones, for consoles that aren’t natively wireless. -NAT will kill a lot of games. Unless there’s a magic way to support uPnP in an enterprise wireless system, you may have to put the consoles on public address space or come up with some other workaround, or give people limited functionality (unless you already enforced NAT on the wired consoles and people are used to it.) -Wiis have been a problem, and require slowest 802.11b rates. Some Nintendos also didn’t work well with some load balancing algorithms. We’ve told Wii users to pay up for the wired adapter, as we can’t support them on wireless anymore.

This seems to be telling him that although his connection speed is pretty good, his uplink/downlink is buffering and could have dropped packet issues (see below). We get basically the same report when we checked this, however we were able to download a debian ISO while streaming some music with no problem.

RE: Wifi Support Staff
We have 200+ buildings, and some 3000 APs. We have four network engineers and two operations technicians. Two of the four engineers have a bit more familiarity with wireless, but nobody that’s mainly a wireless engineer. Operations handles installing APs for small projects, replacing broken ones etc. There’s a separate help desk that assists users in configuring wireless and does basic troubleshooting. In new construction projects, we’ve lately been getting the contractors to hang the APs for us. Not speaking in an official capacity or for my employer in any way, my opinion is that our staffing level is not enough, and having someone dedicated for wireless is a good idea. Larger scale wireless is totally undoable without centralized management, and even centrally managed (controller based) wireless is sufficiently complex that it really would warrant a full-time job to make sure it’s done right. When something goes wrong, it’s invaluable to have someone on staff that’s familiar with what’s under the hood in the system and can figure out configuration anomalies and is comfortable with troubleshooting tools. A lot also depends on the complexity of your environment (size of mobility domain, SSIDs, VLANs, authentication, guest access, VoIP / Video support expectations, location etc.) Our setup is relatively simple, but the engineering staff also does a lot of other things that take up time (DNS, DHCP, RADIUS, MRTG, NAGIOS etc.) -Toivo From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU] On Behalf Of Brian Deem Williams Sent: Tuesday, July 26, 2011 01:33 To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Subject: [WIRELESS-LAN] Wifi Support Staff Hi guys, Just as an inquiry I would like to know what kind of support staff other universities have for their Wi-Fi environment.

RE: [WIRELESS-LAN] Wireless Site Survey cost
You can certainly set dBm limits for signal and survey, or data rate limits, or client density limits, and survey with those. However, there are aspects that just require one to have knowledge or a feel, of campus. For example: Where do people typically congregate and use laptops? Which students typically are heavy users of data and which aren’t? Why is one outdoor seating area really popular and another one isn’t, and might that hold for the students two years from now? Do the MIS or Geography students work on large databases wirelessly from their study lounge? Where ARE the study lounges, sanctioned and ad-hoc in the first place, and where will they be next year? Are you expected to cover a given space for special events where you have hundreds of users, but only a few times a year? Etc, etc. Typical site surveys with well-thought out criteria as basis for planning are certainly useful, especially in the administrative (corporate) spaces, but once you get into the academics you have to put in a lot more external information to make use of them beyond the basic coverage aspect.

We can require that an area will have no less than -68 dBm signal and do the survey to determine what it will take. However, if folks are saying that in a high density area like a ResHall just providing coverage is not enough and we must go much denser what good is the survey? If coverage is not enough then how do we determine our density? Is it just by feel? Up until now I figured I was not going to do a survey. I figured for the cost of the survey I could buy an additional 30-50 APs. When pulling wire I’d have facilities leave a 20’ coil and pull double the wire I originally guessed based on past experience. Then we would just “Throw it up” and see what happens. If we move slowly and do a ResHall at a time we should be able to get a feel for it. Now I have a shot at doing a survey this summer after the fact by using students from a nearby University that has a MS in Networking as an internship. The cost is much less than a professional survey but I have to ask if it is still worth it if capacity is what we are going for? Perhaps I should be looking at a different internship.

RE: [WIRELESS-LAN] AP Enclosure
We don’t always have open access to the hallways either without a chaperone, so the difference between hallway and room in many residence halls wasn’t that major. Also, the hallways are straight, so all the APs would end up within line-of-sight of each other, which isn’t good for RRM algorithms, and staggering them around the rooms improves not only RRM and coverage but also things like location accuracy. Finally, as Joe pointed out, if something in a hallway gets damaged, nobody’s responsible. If an AP in a given student’s room gets damaged, they’re liable for it because it’s part of the structure of their room.

Mike Mike Wiseman Manager, Information Security Information + Technology Services University of Toronto Here’s the backdrop for my questions: For 802.1x authentication on the WLAN, we use PEAP w/ MS-CHAPv2, against our AD environment. This works wonderfully and always has. The rub- we have a set of users not in AD- they are in our ED (LDAP). I’ll thank you not to ask why. These LDAP credential folk cannot use the 802.1x setup as it is, as they are not in AD. LDAP lookups aren’t possible because PEAP w /MS-CHAPv2 doesn’t work with LDAP. Potential options: - add support for TTLS/PAP against LDAP on a new SSID (yuck) - add support for TTLS/PAP on current SSID to make it support two EAP types (never done it here) - insist that everyone be AD (politics) - insist that everyone be in LDAP and go to TTLS/PAP globally This is not a terribly important issue right now, but looking down the road it will come up and so I’d like to get my thoughts lined up. Does anyone else use a single SSID with two EAP types? Or have AD and LDAP both at play in any other way? Anyone using TTLS/PAP that can comment on it’s suitability and reliability versus PEAP w/ MS-CHAPv2?

RE: Student Wireless Satisfaction Survey
We haven’t sent out a survey per se, but we do have a feedback form including a freeform comment box that follows our captive web portal registration as well as an email alias. We’ve gotten some pretty decent information from the form, especially about where faculty and students want to see more wireless, which wasn’t always where we would have thought they did. The “survey” itself consists of two questions, ease of registration and wireless coverage, so it’s probably a bit more rudimentary than what you’re looking for.

Re: [WIRELESS-LAN] WLAN Authentication
Ideally 802.1x/WPA(2), with captive web portal for guest access. In reality, a large number of non-guest users also use web portal and unsecured web, either because host OSes make WPA configuration unduly burdensome/difficult, or don't support enterprise WPA (as opposed to PSK-WPA) at all.

Based on some secondary research we have conducted, it seems like most colleges/universities are using the browser-based approach and that the VPN approach is not common.

RE: [WIRELESS-LAN] 802.11n AP recommendations
We benchmarked a Cisco 1142 and an Aruba AP125 (both controller based) a while back. They had basically identical performance, although they did vary a bit depending on how many concurrent traffic streams you had, how many clients you had, whether traffic was uni- or bi-directional etc. One vendor was better at one thing, the other at another, but neither did clearly better or worse at the end. Obviously, you run into issues such as being able to utilize both 2.4 and 5 Ghz bands to spread the load, possible interference from within or outside of the room, client capabilities etc. If the client doesn't have enough chains, there's not much you can do on the AP end to change that. One big tweak is to kill all the slower legacy protocols and transmit rates if you can, and minimize any multicast / broadcast traffic making it onto the air. Also, if you can deploy multiple APs to further reduce the number of clients per AP / channel, the more bandwidth you have per client. Also, considering you're within a room, you probably do not want to be running full power, so even 15.4W of PoE ought to allow for all chains to operate with both vendors, but you might want to confirm that. -- Toivo Voll University of South Florida Information Technology Communications -Original Message- From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:wireless-...@listserv.educause.edu] On Behalf Of Tom Lowry Sent: Thursday, April 08, 2010 2:41 PM To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Subject: [WIRELESS-LAN] 802.11n AP recommendations We have a robotics research group that wants the highest-speed wireless connections possible.

RE: [WIRELESS-LAN] Encryption and Authentication
Your choices may be limited if you plan to run 802.11n. At least Cisco reads the specs as mandating that you must do WPA2 / AES on 802.11n, other types (TKIP, WPA) will bump you off 802.11n rates. Also consider what your user population is. XP may need a hotfix applied to do WPA2. A lot of older systems, WVoIP phones, barcode scanners, Crestron-type room controls etc. may be limited to WEP or WPA. -- Toivo Voll Network Administrator Information Technology Communications University of South Florida -Original Message- From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:wireless-...@listserv.educause.edu] On Behalf Of David Blahut Sent: Wednesday, December 23, 2009 14:25 To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Subject: [WIRELESS-LAN] Encryption and Authentication Greetings, We are beginning to deploy encrypted wireless and I am looking for some words of wisdom.

RE: [WIRELESS-LAN] Restricting of wireless access in classrooms
Consider what happens if the professor moves class, cancels class, lets people out early, or someone decides to skip class and work on a project for something else in a study area nearby, or is in on-campus dorms sick, trying to access class material online, or any number of similar scenarios. I don't see how these kinds of restrictions are workable - we've told our faculty that the wireless coverage serves people outside of just their classroom, and we cannot disable wireless for just one classroom - it is up to the instructor to police the class if they do not want computers or internet used. That being said, we've seen very few requests like this. -Toivo Voll (Not speaking for my employer or offering official policy.)

So if you could find a way to populate the access policy based upon the user's schedule of classes, you could deny them access to the wireless network during class times. The problem is that some professors encourage Internet access during class, so you would have to have an opt in by a professor/class preference. You could do it by AP, but what if that AP serves multiple classrooms? And, what if the student connects to an AP from an adjoining building? I know of one professor who has their TA's patrol the classroom and monitor what the students are doing. That may actually be cheaper, and more effective than a technical solution. Peter M.

RE: [WIRELESS-LAN] WLAN Deployment-High number of users
LWAPP does bring significant benefits. Whether they're worth the cost is another matter. 1) Radio Resource Management. The system will figure out how to properly interleave channels and set power levels for minimum interference. It's not 100% perfect, but I wager it's better than almost any human can do and can respond to changing conditions. 2) No more manual firmware updates, configuration back-ups etc. All the AP management is centralized; if one goes down or catches the flu it's all on a central console. 3) Roaming. You can have multiple subnets, one SSID, and when users move from an AP in one subnet to the other, the controller(s) handle the roaming transparently to the user. With autonomous APs the client loses connectivity, has to re-dhcp and all that. Depending on your physical environment this can be a big one. 4) Security, authentication etc. stuff. Downside: unless you can get two controllers, you have a single point of failure: controller goes, and you no longer have a wireless network anywhere. You have two subnet/vlan sizing issues; the subnet presented to the wireless users and the network on which the management interface on the APs sits. Neither should be too big; you want to keep broadcast traffic low on the radio side so that broadcasts don't end up eating up all your air time; you want to keep broadcast traffic low on the wired side because the APs (especially old ones) have some issues with broadcast loads. Because all user traffic is tunneled to the controller, it really doesn't matter what network an AP is on, though, from the wired side as long as it can talk to the controller. Unless you have outdoor coverage from light poles and such or a campus with no wired backbone, I don't see much use for mesh. I'd stay away from multiplying SSIDs. We're using a single SSID university-wide to lessen customer confusion and reduce help desk load. Other factors: 1200-series and 1100-series APs can all be converted from autonomous to LWAPP - investment protection. Past that, if you're looking at having to fork-lift hardware (old vxWorks APs) Aruba is a pretty solid option too at very similar price. -- Toivo Voll Network Administrator Information Technology Communications University of South Florida -Original Message- From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:wireless-...@listserv.educause.edu] On Behalf Of reflect ocean Sent: Friday, May 15, 2009 1:52 PM To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Subject: [WIRELESS-LAN] WLAN Deployment-High number of users Hi I run a medium-sized wifi network.We are cisco shop (autonommous access points).Recently wifi users number have reached limits we didn't expect.Because of that,we had to adjust our subnet network in order to support more users associated to the only SSID our wireless network use.
