      Fast 802.11 ac Draft routers are now being marketed. In theory, is the 802.11g radio in my June 2012 MacBook Pro upgradable, should Apple release a firmware update? Or, is the hardware totally incompatible?

      http://en.wikipedia.org/wiki/IEEE_802.11ac

      My old Fall 2006 MacBook Pro came with an 802.11b radio. However, Apple later released a firmware update which allowed it to use 802.11g Draft.

      I presume that an alternative for me would be to get an external USB 802.11ac Draft radio that I could plug into my MacBook Pro.

      What about my approx 2 year old square AirPort Extreme? In theory, could this be upgraded with a firmware update?

      Thanks,

      The difference between 802.11b and 802.11g is just a matter of how the data is encoded. 802.11 ac is a 5 GHz only protocol, so no b or g system can upgrade to

        The difference between 802.11b and 802.11g is just a matter of how the
        data is encoded. 802.11 ac is a 5 GHz only protocol, so no b or g system
        can upgrade to it. They are 2.4 GHz only. I'm sure there will be USB
        radios available, just wait a while. If the AirPort Extreme is the
        simultaneous dual band model, it can in theory be upgraded. But don't
        count on it. Lots of other changes would be needed. And Apple does not
        have a history of being on the bleeding edge of wireless technology.
        They only recently stopped selling 2.4 GHz only devices.

        In case the rest of you are wondering what we are "talking" about,
        802.11ac is the latest version of WiFi. The standard isn't expected to
        be finalized until early next year, but the first devices are shipping
        today (no foolin'). Changes include 5 GHz only, 35% more 5 GHz bandwidth
        allocated to WiFi (they got rid of those pesky avionic radars) and wider
        channels (80 GHz). Plus radios can negotiate even wider channels (160
        GHz) allowing full duplex speeds up to 3.47 Gb/sec using MIMO (multiple
        radios). But expect those units to look like porcupines, with lots of
        antennas. Up to 8 antennas for sending, 8 more for receive.

        There are many more technical changes in 802.11ac. Many of those changes
        are optional, which means that marketing will be doing their very best
        to confuse everyone. Key points are:
        1. there is NO backwards compatibility.
        2. You must be 802.11ac on both ends for it to work.
        3. Expect good equipment to deliver up to 800 Mb/sec over short
        distances. Anything more is a special case, with upgraded equipment on
        both ends.

        Have fun!

          With my dual band AirPort Extreme, I guess there is at least a possibility that it could be upgraded, although I guess I shouldn't hold my breath (Air?). So, if that occurred I could use an external 802.11 ac radio plugged into my USB 3.0 port, and I might get this to work. However, I don't believe that 5 GHz likes the chicken wire inside the walls of a typical stucco wood frame house. That might reduce the range.
