I'd love to see this 11a support, too. I really have little interest in 'g' as it is in unprotected spectrum in the unlicensed 2.4 GHz band. It's only a matter of time until this spectrum becomes useless for data communication. I have friends who bought cordless phones and discovered that they lost their net every time they made a call. Worse, new industrial lighting technology (if it is commercially viable) will legally demolish all 2.4 GHz communications (including cordless phones) with no recourse. I suspect the cries of joy over the compatibility of 'b' and 'g' is partly because systems running either are likely to become obsolete within a couple of years so they can sell new 'a' hardware to everyone. > Not like I have ever needed more than 11 mbit to my laptop... Neither do I, but I work a computer show every year that has offered WiFi to the entire show area including ballrooms, a large exhibit hall, and lots of small meeting rooms. There are a number of complications in this, but own is that the 11 Mb available is shared by all transmissions at single access point. This requires the use of more APs, especially in the exhibit area. Having 51 MHz to share would greatly simplify this. That's why we started offering 802.11a last year. R.
