While I realize that it's a different chipset and technology, the
following review demonstrates that it's possible to get decent speeds
at a range of perhaps 6 ft.
http://www.tomsnetworking.com/Sections-article59-page1.php
It's 13 pages and has quite a bit of info on how it all works. Note
that they had to switch to faster PC's in order to prevent the PC from
becoming a bottleneck.
This comparison of Super-G and Afterburner is also enlightening:

If you read the fine print, 108 is maximum peak burst speed. Broadcom
claims 60Mbits/sec sustained thruput, which the reviewer was unable to
verify. Both G and Super-G need to slow down to a crawl every few
seconds to check for the presence of 802.11b radios (to minimize
interference) and will not recover back to higher speeds for quite a
few seconds. Your high performance race car may be capable of going
100+ mph, but that does you little good on crowded city streets.
I like the articles conclusions:
As far as the question of whether Afterburner or Super-G is "better",
the answer for many (most?) users is probably neither. The only users
who will get the maximum benefit from "enhanced" 802.11g products are
those who:
a) Are willing to buy / upgrade all parts of their wireless LAN with
products using the same enhancement technology, from the same
manufacturer
b) Make sure all parts of their WLAN are operating as the same,
latest, firmware and driver revision levels
c) Don't have any 802.11b WLANs within range
