Inasmuch as anyone with an ICBM (Intel-Chip-Based-Mac) has 802.11a capability, and such devices have been gaining increasing traction among geeks of late, I'm not surprised. The latest Airport Extreme base station from Apple is A/B/G/N (the Express is still b/g). ---rob Marshall Eubanks <[email protected]> writes: > The IETF experience is that enough people run 802.11a to take > significant load off of the {b,g} network. > > Marshall > > On Feb 15, 2007, at 9:45 AM, Pickett, McLean (OCTO) wrote: > >> >> >> Works well if everyone has 802.11a/g card.
