PCMCIA/PCI Wireless Card 802.11a/b/g for private Mesh

Hello Mesh- and Wireless geeks,

since my 4 Mobilhomes and my Truck is nearly complete, I have some problems
with the Wireless connection between the Mobilehomes, the Truck and the
Trailer.

I need a realy powerfull Wireless card which support a/b/g standards in a
Wireless-Mesh to connect all 6 permanent together (as Relaystations to
increase the range, and such)

The Problem is, that the Proxim Combo-Cards (PCMCIA) are TO expensive as that
I can install 4 of them in each Mesh-Router... (= 24 Cards required plus the
Laptops)

Can anyone can recomment me less expensive international usable cards?
In general I prefer PCI with external antenas since I have already of the
Proxim cards.

Note: With the Proxim Cards (using 802.11a) and a 10dbi OmniWave Antenna
(on a telescop extender with 8 meter I reach at least 1500 meter
distance in a free terrain by 54 MBit without fallback)

Thanks, Greetings and nice Day
Michelle Konzack
