Radio transmit power and receive sensitivity is similar (often identical)
between PC cards and access points, so given equivalent antenna
configurations, range will be identical.
 
What you will not get from an Ad-Hoc network is full connectivity between
all nodes---some may become hidden. This might not be a problem for
your application, and if it is you may be able to fix it by routing, each
node having its own little subnet to the router.
 
300ft is optimistic for any 802.11b equipment with the typical built in,
low gain antennas, especially if there's any objects in the path (walls etc).

Subject: [Aironet] running an aironet Linux router

I am in the process of getting a really old, almost unusable laptop up and running, with one pcmcia card connected to a cable modem, and the other (an aironet 350) in ad hoc mode. Everything was workinjust fine til the hard drive decided to die ...  anyway, a second aironet 350 card in a new laptop will get onto my private LAN and the net via the aironet router, which will run dhcp. My question is: is anyone else doing this?? what sort of range would I be looking at? I am sure that it would be no where near what I would get running with an AP in infrusture mode. Someone in another mailing list claimed to get 300 ft range from his wireless 'router' box, which was an old 486.
