These people are adults, and as such, should be able to decide on their own if they are going to attend class. The college is not their parents, and it's not a daycare.

What's next, disable WiFi if that don't take out the trash from their dorm room, or decide not to shower, or protest some decision the campus made, etc? Will you disable WiFi except in the stadium during a game, so as to force students to attend? Something wicked this way comes, and it's at UTK. I'm curious, does your honor code, guide to student life, etc. state that attending class is mandatory? If not, how are you able to levy sanctions against a student for not attending (disable WiFi)? I can see it now... Student doesn't show up for class. Said student is in trouble, but can't the necessary help (send email, make a skype call, etc.) because none of his/her devices can connect to the network. Student becomes seriously ill, or dies, etc. because of this new policy, and the college faces a huge lawsuit. Don't get me wrong, it's an interesting technological solution, but it's still wrong in my book. If a student is not attending class, your dean of students needs to bring the student in for a discussion. Jeff Hanset, Philippe C phan...@utk.edu 4/1/2011 9:22 AM All, University of Tennessee has had some class attendance issues lately, especially with Sophomores. We came up with a location based wireless solution that could fix this issue. We have built a database of rooms surrounding Access-Points that we correlate with a class roster. Basically if a student is supposed to be in room x at time y, our filtering only allows the student access to a set of access points surrounding that room during that time. No wireless elsewhere. Dormitories are included in the algorithm. If you are doing something similar, we would like to know some of the caveats.

Re: [WIRELESS-LAN] WiFi blockers in classrooms
(Macro towers, DAS, etc..), is that students that cannot join the Wi-Fi network in classrooms will find other wireless technologies to get access (Smartphones, tethering laptops, air-cards or just a book, but not the textbook!). So, students that can afford cellular-data access can still be distracted. This could be an interesting research. The hypothesis would be Is it about who you know or what you know or TextBook VS FaceBook ;-) Philippe Univ. of TN On Nov 19, 2010, at 9:45 AM, Luis Fernando Valverde wrote: Yes, we do.The idea is to block any source of wireless connection to the WiFi network. lf *From:* The EDUCAUSE Wireless Issues Constituent Group Listserv [ mailto:WIRELESS-LAN@LISTSERV.EDUCAUSE.EDUWIRELESS-LAN@LISTSERV.EDUCAUSE.EDU] *On Behalf Of *Hanset, Philippe C *Sent:* Jueves, 18 de Noviembre de 2010 07:42 p.m. *To:* WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU *Subject:* Re: [WIRELESS-LAN] WiFi blockers in classrooms And do you plan to block air-cards on cellular as well with that jammer?

However, we use our classrooms for multiple academic activities (MBA programs, seminar and in-company events), and we need to find a simple device to block the signal in a 10-20 meters radius / classroom. So, the adjacent classrooms can work with the signal of their own access points (some professors require Internet signal to teach their sessions – internet dynamics, simulations over the internet, cloud computing services, etc.). I have heard that this is implemented in some universities in the USA, Europe and Asia (for instance, I was told that in the Indian School of Bussiness’ classrooms there are switches to enable/disable wireless signals.

Re: [WIRELESS-LAN] WiFi blockers in classrooms
Oh, I don't think it's worth it; I believe this to be an instruction issue, but there are good points on both sides. Wouldn't need re-authentication; just some method of kicking off those authenticated users at specified times. I'm not a programmer, nor do I know if this is done in any product, but I'd think it would be possible to do. The sharing of access creds is a good point. BUT, if the authentication was by machine and not user, that would go far in solving that issue. For example, Enterasys NAC authenticates on MAC address that has been registered by a user. SO the algorithm would be look at class list, look at student user id, look at MAC(s) registered, perform individual block action. And I will say again, yes, a lot of work to solve what I think is an instructor issue, and yes it does nothing to address 3/4G. But it's an interesting academic exercise...if you'll pardon the pun :) Greg On Fri, Nov 19, 2010 at 12:13 PM, Curtis, Bruce bruce.cur...@ndsu.eduwrote: On Nov 19, 2010, at 10:35 AM, Greg Schaffer wrote: Finally, with regards to WiFi blocking, I don't think the simplest solution has been offered yet.

I don't see why not, but I may be missing something(s)... Greg You would have to tune the wireless system to require re-authentication quite often, otherwise students could just connect to the network 5 minutes be fore class and still be connected during class. Also this would create a situation where students are highly motivated to share their access credentials with others. Is the administrative overhead to enter all of the data for class times worth it when the future will only bring higher and higher percentages of students with smart phones or netbooks that access the Internet through 3G and 4g celluar? ** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/.

Re: [WIRELESS-LAN] Wireless site survey tool
Title: Wireless site survey tool AirMagnet has a new tool called Surveyor that they demonstrated at InterOp; I think it's out, and the list price was in the $2K range. Runs on a laptop. I haven't looked at it yet but it does look like a good tool for site surveys. I don't think it (or any product for that matter) can "auto discover" the exact location of an AP, but the resulting survey of signal strength and distribution should be enough to "figure out" where it is.
