GA Tech deploys 802.11B, readies for 802.11A

", 0, 0);


Promising to upgrade its wireless system to 802.11A standard that supports bandwidth speeds of up to 50MB, Georgia Tech has deployed an AirPort-compatible 802.11B wireless network throughout its campus and says it has developed its own "authentication program requiring wireless users to log in through a web browser before access to the Internet is granted. If a user’s connection is inactive for a certain amount of time, the authentication system closes the user’s access, deterring potential hackers from taking advantage of the connection."

    50MB ... not

    Time for some fact checking, MacNN. 802.11A is the older standard that runs at only 2Mbps (that's 2 megabit), as opposed to 11Mbps for 802.11B, aka AirPort. (And most 802.11B implementations, like Apple's AirPort card, can really only support 5.5MBps because they only run at half duplex.) Still, as long as it outpaces my DSL connection I'm fairly happy with it :-)
    It's unclear what the article means by "50MB" (is that bytes or bits?) but either way that would presumably be some as-yet-vaporware upcoming improved version of the technology.

    There is more information available about this (as well as a post by me, the LAWN admin) at Slashdot:

    Re: 50MB ... not

    To the idiot above, why don't *YOU* do some fact checking before making such unfounded remarks.
    Check out 802.11a: Making Space for Speed before you speak any further on this issue. 802.11a, working in the 5Ghz band, is in fact capable of 54MBps (and a capital B means bytes Mr. SmartyPants). Am I a genius? h*** no, could my statements here be off? h*** yes! Do I care? No...my statements don't need to be accurate, MacNN's statements do, my point is simply that they ARE, as are the statements (at least, one would assume so) made in the article linked above ("Making Space for Speed").

    Your comments are not needed, neither are mine, I just wanted to set you straight.

    Web-based authentication?

    That seems like a pain to me. I know my school (Carnegie Mellon) has a wireless network extending to all academic buildings, and we have no such authentication to worry about. The network is a "closed" network, but that just means that I need to type in the name of the network when I try to access it. Of course, Apple's AirPort software seems to remember it on waking from sleep.

    I don't know that there's a point to all this rambling, but I think the authentication scheme is overkill. You actually have to be within a certain area to use the network anyway, and I can't imagine they would let certain students use and not others, so there almost doesn't seem to be a need for authentication at all. You still need authentication for each specific network app, but authenticate just to use the network at all? Seems kind of strange to me.

    Tech at Late Comer

    Lots of the posts on slashdot mention that Tech is behind the curve. However, most of the other shcolls with wide spread installations are private. GA Tech is a relatively large State school, with all of the baggage attached. The authentication scheme is like that to use any of the other systems on campus. In most buildingds the wired network had to know who you were before it would talk to you, so atleast this adds flexability.

    To to the "idiot" above who asked for fact-checking, maybe you should do some of your own. The 802.11a standard supports transfer rates of up to 54 Mbps with a LOWERCASE 'b' -- that's 54 Megabits per second, not Bytes -- which translates to about 7 MegaBytes per second.

    blah, no subject

    Thank you for the correction on the Mb/MB issue...I didn't feel like going back to the article to verify if it was bits or bytes, and I did qualify my statements as to say they may not be accurate but that they didn't need to be either (I don't get paid to type this stuff, MacNN does).
    Peace.

    Actually...

    Acutually, from what I have read in other reports from the actual 802.11a standard, they are coming out with a 50mb/s (notice the lower 'b') wireless technology. The 802.11b standard uses less bandwidth than the a series.

    I guess the real question is it feasible and can it quickly be adapted to the Mac (like a firmware update or something). It was also noted that this technology won't be available for about one year.
