    This is why we haven't seen Airport 2.

    Steve is waiting on 802.11g which is backward compatible and supports both 802.11a and b devices. It peaks out at 54Mb/s @2.4Ghz.

    Problem is:

    802.11 networks interfere with Digital Satellite Radio signals so there will be some FCC battles before large implementation of 802.11 can take place.

    Huh?

    :confused:
    I have Airport 2.

    I have had it for a while. It has been out for a long while.
    Airport 2 added 128 bit encryption, and extra port to wire it into an existing network, AOL support, etc. The original Airport (Airport 1) didn't have these features.

    2nd Generation Airport (Airport 2)

    Perhaps you mean Airport 3.

    Don't worry, it seems that almost everyone here says the same thing with regards to Airport, so you're not alone.

    whoops.......

    Since Apple's "Airport 2" is 802.11b+ Encryption I tend to think of it as Airport 1.5 cuz it's not a whole upgrade.........even so yer right it would be A3......if not A5 if Apple makes more incremental changes.

    Re: 802.11g

    What satellite radio are you talking about. I have XM Satellite Radio in my car and house (my wife works there) and its awesome. But 802.11g is short range and I don't see how this would have that much effect. Is it a simillar frequency or are we talking a harmonic? I might have to ask one of the RF engineers here at work.

    The reason there is not backward compatability is because 802.11a and 802.11b operate at different frequencies, 5GHz, and 2.4GHz, respectively. Apple has never used 802.11a, only 802.11 (Graphite base station) and 802.11b/b+(snow base station/snow base station with interoperability with Bluetooth).

    802.11g will be the new wireless standard in the future, although bluetooth will be added by Apple to implement a couple of wireless devices, 802.11g is the next big thing.
    Don't forget that Apple and Ericsson signed an agreement, but nowhere there is mentioned that it is only about Bluetooth, it's about delivering wireless mm content. Ericsson itself is experimenting on this 802.11g:
    http://www.ericsson.com/bluetooth/news/inthepress/default.asp?action=spec&id=281
    Although still under development (article dates back from 20th december)
    and a wireless agreement between Apple and ericsson points out to...
    right, Apple's next wireless move: 802.11g

    Huh?

    I knew that.

    I wasn't talking about 802.11a/b compatability. I was talking about 802.11g which will supercede BOTH and provide mutual backward compatability. This means that BOTH older device types CAN use the "g" type base stations.

    I was aware of the fact that you were talking about 802.11g, and know that g will supercede both, and bluetooth.
    I was just backing you up, and adds some facts to the 802.11g thread.

    Clear things up

    I just want to clear things up here in case anyone is confused. 802.11b and 802.11g are compatible with each other, but neither of them is compatible with 802.11a (because it is in the 5GHz range, while b and g are in the 2.4 GHz range).

    Re: 802.11g

    Anybody seen this on macOSrumors, Apple has apparantly demoed a newer version of airport @112Mbps:

    Apple has reportedly demonstrated a 112Mbps version of its Airport wireless networking technology for educators in certain West Coast US locations, in anticipation that the new standard, which is up to ten times faster than the current Airport and can sustain original Airport speeds at distances upwards of 50% greater than today's devices. Release dates vary between reports, but the general consensus is Apple will release at least a partial implementation of this technology at Macworld New York this summer, just in time for the 2002-2003 school year buying season.

    Re: Clear things up

    :confused: Really? Are you sure about that?

    I have read and heard everywhere, including TechTV, that the big draw for 802.11g is that you can use it with both 802.11b and 802.11a.

    If I am mistaken, then I would like to see where.

    Can you provide a link to information about 802.11g and how it isn't compatible with both 802.11b and 802.11a?

    Thanks

    Re: Huh?

    Actually,

    802.11a is not compatible with 802.11b. 802.11g will not be compatible with 802.11a. This is why not a lot of companies are switching to 802.11a. They know once the new standard is released, their equipment won't be compatible. If you buy a 802.11b station/card, it will work with the new 802.11g station/card.

    incompatible

    Sure. In the latest MacAddict, there is a whole section on the future on Mac things, and they talk at length about the compability, and incompability of the 802.11 standards.

    Go look it up.

    Go to: www.IEEE.org

    you can download PDF's of all the 802 standards and compare them side by side.
