      Are they forgetting that these 11Mbps or 54Mbps speeds are the aggregate total for an access point? I hope not.
      Also, if you get a powerful enough microwave or something else that transmits in that 2.4Ghz wavelength it should be fairly easy to bring down the entire campus "phone, cable TV, and Internet services."

        Not to mention that that aggregate bandwidth of 11 Mbps or 54 Mbps is the bandwidth provided at the raw physical layer. Even when you get to layer 2, you lose a lot of that bandwidth due to all ACKs at the MAC layer, the various timers (inter-frame delays). Then add on top of that the retransmission of lots frames due to interference and you're down to less than 10 Mbps of bandwidth. I've seen data from Vivato that indicates that you get even less than that (around 5 Mbps) in real-world conditions on a 802.11g network. That's about 10% usable bandwidth. Shared. That's not nearly enough. That's enough for maybe one TV channel and nothing else. And don't get me started on the latency...

          Not-quite-so-dumb-question:

          Would wired gigabit be enough for a decent cable tv selection, assuming you were competent to set up the multicasting correctly? And how much bandwidth would it eat up per channel, and what kind of video might you get?

          Is it truly enough bandwidth that you could consider wasting a bunch of it on say, a basic cable setup?

            Yes, if the multicasting is done correctly.

            The short answer is that you don't actually have to multicast all twelve billion (slight exageration) channels simultaneously all the way to the set top boxes, just whatever 12 channels the people on the LAN are using (looking at this from the POV of a residential cable system based on Gig-E fiber to the home). If this is done inteligently, you can multicast only those channels being viewed and use IGMP snooping to figure out what to start multicasting from the cable head end. Depending on the exact network configuration (PON, active, etc), the multicast pruning might be done in the network, in the CPE, etc.

            As for bandwidth, yes, it does matter what codec you use, but MPEG-2 for standard resolution TV is 4-6 MB/sec (IIRC). HDTV is another matter entirely, as it's huge (especially when uncompressed).

            I'd write more, but it's time for lunch.

    Wireless purely for the sake of wireless is just a stupid idea. I'm assuming they pretty much already have most of the infrastructure they need. Don't the dorms and offices and classrooms already have phone lines??? Also, the bandwidth of Wi-Fi is puny compared to gigE, which is what is required for some on-campus applications like streaming video (I'm a student at IU and we do things like that sometimes). Plus there's the whole security problem. This just seems like one big joke...

        It depends on what the network was like BEFORE the switch to wireless. If the buildings were all wired with Cat-3 cable to the wall port, why rewire with Cat-5 and then do it again in a very few years when you need fiber or some new Cat-X cable?

        Maybe wireless isn't as good as wired yet, but it isn't that bad either. The overall savings they may realize by no longer having to run new cables to every friggin wall port should more than make up for any cost now. When wifi improves, just swap out the access points.
        • Dartmouth's wired network is fast enough. All the dorms / academic buildings are switched 100Mbit internally (except for a few Gbit labs), and the backbone is all GigE fiber. Of course, the old cable pulls are all still there from the Cat3 Appletalk network, too... So yeah, to some extent, it's overkill / flashiness.

      The simple fact is that today, in 2005, wireless doesn't work well at all. In the cases where it does work well, check how close the AP is. You'll see that it is so close that you might as well be using a cable anyway.

    TFA IT'S not that he doesn't like them or doubts his teaching ability, but Thomas H. Luxon, an English professor at Dartmouth College here, wants to see his students less next semester, hoping they will learn a lot more without having to look at him in a classroom. Professor Luxon, who teaches courses on Shakespeare, wishes they will instead be watching scenes from "The Merchant of Venice" or "Macbeth" on their PC's while sitting on a lawn, in a coffee shop or while relaxing in a dorm room. "That will be really cool," Professor Luxon said. "They could watch it on their own time and in their own place instead of having to go to the classroom or the media center. That means they could review it as often as they like, and they don't have to see it just once." Professor Luxon is able to release his students from the shackles of forced classroom movie viewing as a result of a major wireless convergence project that has taken Dartmouth's phone, cable and wireless systems and condensed them into one Wi-Fi network. The project, officials say, keeps students on the forefront of wireless technology, and opens up endless educational and teaching opportunities while saving the college millions of dollars. The switch, which started in 2001 and will be complete with the wireless cable rollout this fall, includes the addition of 1,400 wireless access points and 24,000 wired ports across the campus of the 236-year-old college, the first in the country to completely integrate its communications systems into a wireless infrastructure. "This really improves our ability to deliver types of information services that enhance teaching and learning," said Brad Noblet, Dartmouth's director of technical services. The first phase of the cable rollout will put the school's cable television system online. After that, students, professors and anyone else on the overall network will be able to make up his or her own "channel," showing movie clips, video projects or presentations with cable-quality video. The college's public affairs office hopes to have its own channel as well. It could also be used by students to shop for classes during course selection because they could view a few minutes of a lecture or discussion on the network, and by professors to provide discussion materials before class. Dartmouth also hopes to put all its public lectures and forums on a cable network instead of on the sometimes gritty streaming video now available. "We're really at the front end of this," said Jeffrey L. Horrell, dean of the libraries and librarian of the college. "It's not yet clear where the boundaries are." The new network could even change how students write papers. They will not replace words or writing, but might enhance, say, a paper on "The Merchant of Venice" with a clip of the actor Patrick Stewart explaining the method behind his portrayal of the character Shylock, said Professor Luxon, who teaches a course on the play. "Imagine writing a paper about one of these performances and including a video clip in your paper, like you would a quote," he said. "Now your paper isn't on paper anymore, it's on a Web site or a word file." The convergence project is meant for educational purposes, but it is not bad for entertainment, either. Students will be able to catch the latest episode of MTV's "Pimp My Ride" or any other television show anywhere on campus - including in class. While that is one more worry for professors who are now used to students staring at screens, they hope that the interaction and stimulation of a class will detract from the desire to tune in to "TRL" during sociology, Mr. Horrell said. Students, many of whom did not know about the new service, are enthusiastic. Jean Cowgill, 19, a freshman, hopes to use the network to watch materials outside of class. But, Ms. Cowgill said, the cable access might backfire. "That sounds amazing," she said. "But I don't know how great it will be for my study habits." Wireless data has been available here since 2001. Its success led the technology department to combine it with the college's

    I work for the reseller Networked Information Sytems [netinfosystems.net] that sells them all their Cisco gear. I was one of the shmucks to go and flash all the IOS images and config the vlans, etc.

    The article leaves out some cool stuff like they use Vocera [vocera.com] which act like StarTrek communicator badges. I get a kick out of asking where a specific person is and because of the aceess point they are connected to the computer answers back with their location and if you would like to call them, all while walking across the campus. And they also leave out the fact that they don't bother using any security on their 802.11 though.
