I have found that they use the same chipset as the WaveLans use.

I trolled around http://www.networking.ibm.com/wireles/products.htm a
bit. Hard to say exactly what the deal is, but it sounds an awful lot
like WaveLAN. They power output is only 100 mW (instead of 250 mW for
the Lucent cards). They also list a variety of antennae that they sell,
although not for the PCMCIA card (no big surprise). Sort of a pity --
either a directional or flat-pattern would be really nice, indoors or
out.
The picture of the card is lots different from the 900 MHz WaveLAN.
Someone who has seen a 2.4 gig card might take a peer and let us know
what they think.
I see two uses for this card: 1) roaming my house and 2) putting
some kind of directional antenna and getting good throughput accross
town to a friend's house.
IBM claims about 3 mile range with direct line of sight. My experience
is with the 900 MHz radios, but given the reduced power of these cards,
that number seems about on target (half the power should mean about a
quarter the distance). You might do better with a dish antenna, but
those get pretty big -- and you would have to build it yourself.
Jim -- call me if you are going to order some of these....
