Nope.
And noone else has one (that works) either, in most environments.
The 108Mbps spec uses most of the 802.11b/g spectrum. Any other APs on any other channel, anywhere in the band will interfere (along with Bluetooth, which also uses most/all of that band).
You also interfere, to some degree, with everyone else's 802.11b/g signal.
Given the popularity of wireless these days, it's unlikely that you'd ever get anywhere near full throughput on a 108Mbps system in anything but the most remote locations.
Good Luck
