Are there any projects building infrastructure 802.11b WLAN?

Hi all,
How can I use one USRP as 802.11b AP and other USRPs as clients to build
my WLAN?
I am trying to build a WLAN using GNU Radio. I have two clients (two
USRPs)Â and one AP (one USRP). The AP connects to the Internet through
Ethernet cable. My clients (without ethernet cables) want to browse the
Internet through the AP.
Thanks in advance!
