802.11n WiFi Card in new iMacs?

“MacRumors user, Peace, discovered that the wireless card in the new Core 2 Duo 20-inch iMac is identified as a Broadcom 802.11n Network Adapter under the latest version of Vista,” arn reports for MacRumors.

“The Broadcom 802.11n adapter provides a draft version of the 802.11n wireless specification which is not yet finalized. The new protocol promises significantly faster transfer speeds than existing 802.11b and 802.11g wireless networks,” arn reports.

The real data throughput is estimated to reach a theoretical 540 Mbit/s (which may require an even higher raw data rate at the physical layer), and should be up to 50 times faster than 802.11b, and well over 10 times faster than 802.11a or 802.11g.

“There has been speculation that Apple’s iTV device will also incorporate the 802.11n protocol. Steve Jobs described the wireless technology only as “802.11” — without specifying the exact protocol,” arn reports. “The new card capabilities were discovered when booting the latest version of Vista. The 802.11n capabilities of the device do not appear to be recognized under Mac OS X at this time.”

  1. That makes me love my new iMac even more (as if that was possible!!). But is there any other ways to confirm that?? Like any programs on the web that can determine the protocol used in the wireless card??

  2. “Interesting he used vista to figure out what the card was. This is empirical proof that vista is, in every way, shape, and form, better than OS X (and about 3 times as big!).”

    I’ll assume that was sarcasm.

    In any case, why would OSX recognize a device with a non-existant or currently usable standard?

  3. I don’t think I’m going to click on any link that includes “Anal” and “Fist” while I’m at work….

    On that note….has anybody looked at a recent iMac’s wifi hardware with some of the Mac hardware snoops to see what they say?

  4. Most Apple retail stores are OUT OF STOCK on Airport Extremes, have been for a few weeks, with nothing in the pipe…

    The Mac wireless insecurity problem is bigger than we were led to believe, a hardware flaw most likely.

    I knew about this a few years back, and have gotten completely off wireless, even bluetooth.

    I live in a *cough* very high *cough* military sensitive *cough* neighborhood so I have them as well as their adversaries attacking my equipment regularly.

    As always Apple ignores my phone calls and emails on the subject.

  5. Of course it is extremely possible that Vista incorrectly misidentified the wireless technology used by Apple. It is possible that the Apple hardware simply fit a Broadcom definition.
