They are actually quite commonly available in computer stores for about US $100. They are about four inches long by about 2.1 inches wide by about .15 inches thick, with a thicker protrusion near one end. There are also some smaller ones, but they're somewhat harder to find and much more expensive. Somehow I suspect that this isn't really the information you were looking for. But an 802.11b PCMCIA card (or CF card) is going to be *much* easier to connect to a PIC and deal with than just about any other approach to implementing 802.11b. -- http://www.piclist.com hint: The PICList is archived three different ways.
