I'm freaking out. 5Ghz hostap mode on a 2005 tech?

I'm freaking out! I dug out an HP TC1100 from 2005, and there's an Atheros card in it. And the card has a 5GHz hostap mode!!! But when I run "ifconfig -m" on the interface, it tells me "media OFDM/54Mbps mode 11a mediaopt hostap,turbo" as the maximum available speed, I guess. I'm so confused. I thought 5Ghz could do more than 54Mbps. Does anyone know what I'm dealing with here? And what's the 'turbo' option? I was excited because I couldn't find any 5GHz hostap mode cards, and there I have an ancient card lying around with the capability?
 
Ok, apparently the cool man page for ifconfig explains the Turbo part.

Man Page for ifconfig

Some 5GHz channels can enable a proprietary Turbo mode for the HostAP mode of Atheros cards. You can see which channels have it by "list freq". The Turbo mode is enabled by default if you choose these specific channels for your SSID.

You must have a client card that supports that Atheros Turbo mode stuff, or your device will not see the Turbo enabled Wireless network.

I am still confused, though, why I am able to broadcast on 5GHz channels but only at 54Mbps speed. I thought all 5GHz channels were higher speeds. Is it because of this Turbo mode? Atheros needed the 5GHz spectrum for the Turbo mode, so it just kind of enabled the 5GHz channels individually at the lower standard speed for whatever?
 
You can still use the 5ghz band to limit interference. But the speed will be the same. Until some day when FreeBSD does enhance its support on this.

Yep, 5GHz is nicer even at slower speed. But FreeBSD development is irrelevant for this chip because it cannot do more than 54Mbps by design.
