802.11n utilizes a technique known as Multiple-Input Multiple-Output (MIMO) to achieve the faster performance and longer range, and while it offers seamless connectivity with older products, the performance of an 802.11n network will slow down if slower devices are connected.

Does my Mac support 802.11n?
These Mac computers support 802.11n in the new AirPort Extreme Base Station using the included enabler software:
iMac with Intel Core 2 Duo (except 17-inch, 1.83GHz iMac)
MacBook with Intel Core 2 Duo
MacBook Pro with Intel Core 2 Duo
Mac Pro with AirPort Extreme card option
The catch is, you need to install that "enabled software" only supplied with the new Airport Extreme base station. What if you would like to use a competing base station from another vendor?

There is always a price to be paid for implementing a standard before it is out of the oven. I hope Apple has a soft landing in mind for us (in this regard).

Once the .11n specification goes from "draft" status to official standard, I can only assume Apple will have provision for users to update to this bona fide standard with a firmware release. The question is whether existing legacy wireless cards in the Mac kingdom will be able to cope with this.

Quote:<hr />Is anybody excited about using the new base station with a hard drive as an inexpensive NAS? That's something I never heard about as even a rumored feature. I wonder if attached drives spin down when they're inactive.
The new base station also enables you to share USB-based printers and hard disk drives with the network, and can support a hub, so you can attach multiple devices. Software included with the device enables you to create password-protected accounts, or limit access to certain files and folders. The device itself can support up to 50 users at once.
