Greg, your suggestion makes sense in many ways especially as those students should be in the class! If they are not in class their "punishment" is no internet on campus... I would have a concern about what happens when a class location is moved (room or time), or a student changes class/module/course midterm whether this information is fed back correctly and in a timely manner. However this would be easy to implement as long as the student records systems had accurate information. (Which of course they always do ;-) )

I have had the opposite experience when I have taught. Now, I should say that I am in IT and taught as an adjunct one intro networking class to 25-35 students. At the beginning of the first class I told them that I am not going to regulate use of electronic devices in class; if they wanted to watch videos all during the class that was their decision *so long as it did not interfere with the class or other students*. I also made it clear that they were responsible for all work in class and not paying attention in class was not a valid reason for extra attention during office hours. It worked well, but it might have been a function of the smaller class size. Tinkering on a device did not relieve you from being called on, and class participation was part of he grade. Having said that, I never had anyone complain of another's laptop use bothering them; if I had I would have adjusted. Actually, I only had a few using laptops, and often they would use it to research class topics as I was talking. Bottom line, in my experience (limited), letting students decide worked the best. But I can certainly see the other side. Finally, with regards to WiFi blocking, I don't think the simplest solution has been offered yet. If the wireless is accessed via credentials, create an LDAP/AD/Radius interface that can disable those accounts during a specified class time, or on command from the instructor. Can it be done? I don't see why not, but I may be missing something(s)...

I teach an intro networking course to 120 students per semester. I try to "edutain" whenever possible but it is impossible for me to compete with the Internet for the attention of most students. Network guys/gals need to understand this. If you think you can command the attention of 120 students staring at laptops and smartphones in class, give me a call and I will hire you. I also know enough about wireless to know that dealing with this problem at the physical layer is probably not practical, for many reasons -- financial, technical, and behavioral. If there is any hope for a technical solution, I could envision a system that ties together class rosters, authentication, and location services. But even with that, you don't have any control over commercial wireless services. My current policy is no laptops or smartphones in class. I give students a 10-minute grace period at the start of class for urgent communication. Some students complain about this policy but the majority understand why I do this and feel it helps them focus on course content. The most valid complaint comes from students who take notes in class on their computer. I'm somewhat sympathetic to that, but if you've ever sat next to someone in a meeting who is taking notes on a laptop, you know that the keyboard clatter is distracting, sometimes infuriating. I encourage students to take notes by hand or record the lectures for later transcription, which helps with retention of course content. In my wireless course, which only has about 25-30 students, I have been more hesitant to implement a no-tolerance policy, but even there, I think the only way I could get away with that is to change my presentation style so that I spend more time in the back of the room checking screens and scolding abusers. Alas, one wonders whether there is a solution that will be acceptable to all. Last semester, our Dean implemented a no-laptop policy for faculty meetings, offering to reduce the meeting time by 30 minutes as an incentive. Before this policy, it was a very strange experience, with over half of the faculty attendees working away at their computers while we were supposed to be deliberating about important issues. The policy seemed to be working pretty well until the iPad was released. Now we have faculty coming to the meeting with iPads. It's not a laptop, right? dm Dave Molta Associate Professor Director, BS in Information Management and Technology Assistant Dean for Technology Syracuse University School of Information Studies 212 Hinds Hall Syracuse, NY 13244 315-443-4549 djmo...@syr.edu On 11/19/10 10:30 AM, "Hanset, Philippe C" <phan...@utk.edu> wrote: Luis, Cellular networks (usually licensed spectrum) are not under the same regulations as Wi-Fi (usually unlicensed spectrum). In the US, for instance, one cannot interfere with the licensed spectrum (jammers etc...), and when it comes to the unlicensed spectrum (e.g. Wi-Fi), you have to comply with Part15 of the FCC. Can you interfere with cellular networks in Nicaragua or Costa Rica? (I would double check...otherwise students will remind you!) The point I want to make with Cellular access (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.

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. I emailed them, but I haven't received answer yet).

But as other respondents have said it's not really a technology issue, you design your WIFI for full coverage for a reason. Students use laptops to take notes like we all used to use notepads. Similar to using notepads to draw on when bored in a lecture or write notes, our current students use their laptops to use facebook etc. The issue lecturers should look at is why their students are so bored in their lectures that they are losing interest!

However, our AP heatmap shows leakage from AP's above and below the floors where the classroom are. So, in a nutshell, it wasn't worth it (blocking that is). Especially true once you incorporate emergency notification via 802.11x. I would agree with other colleagues comments, it's an academic/classroom/Professor issue. Northeastern, I believe, did not roll out 802.11x in the classrooms, because the Professors did not want it. The idea behind this decision was "you don't need wifi to take notes".
