The only secure way to insure against AirSnort and other packet
sniffers is with a 3DES or better VPN.  Any business that requires

For which there are several antenna options available.  Fleeman,
Anderson & Bird's Orinoco to N-Male Adapter (www.fab-corp.com)
comes in very handy when you need a few more decibels.
