I jus got a laptop and am reading up on wardriving. And im about to get into it. But i want to get a 802.11a card to do this. So im looking into this stuff and come across a tutorial kinda introduction to this stuff at wardriving.com and it says at the end "What can be done to stop it" and it talks about waiting for 802.11a.. but i want to use 802.11a because its alot faster 54mbps versus 11mbps.. Can i still use an 802.11a card? or is it somthing completly different?
