according to this article, IEEE has slowed down the 802.11g standard to 10-20Mbps. What gonna happen to Airport Extreme?

I'd guess nothing, as long as you don't update the firmware.

It doesn't look like they've slowed it down very much. They're just saying an extra "warning message" was put in to notify 802.11b devices that an 802.11g device is running.

The article states that true throughput will probably be about 20 Mb/s for a dedicated 802.11g network. Isn't it about 22-24 Mb/s right now? That's not that big of a change (at least not for the average home user).

Even on a mixed network, they're talking about getting true throughput of 10 Mb/s. That's still much better than the 4-5 Mb/s or so that I'm getting right now with my 802.11b network.

I think the original poster is confusing megabits per second with megabytes. If it went from 54megabits per second, to 10-20, it would be major.

802.11g != standard

not yet. still no ratified...

either way, this is the problem with jumping into something before it is a true standard.

No they are not confusing Mb with MB. The article is talking about throughput, not raw data rate.

The IEEE cant have dropped it- it hasnt even formally acknowledged 802.11g as a wireless spec, let alone a WiFi standard, as it would have to be ratified by the WiFi consortium.

as posted by others on slashdot, the 54mbps is the raw data not the real transfer rate. 802.11g is rated at that anyways. although from other measurements it seems like the max is 24mbps, but 20 is still good nonetheless.
