I go to CU-Boulder, campus has about 40 access points, about 2/3 are for use in various schools i.e B-School, Law Library, and the E-Center, the others appear to be just for personal use or maybe deaprtment use, almost none of them have WEP, although there is a MAC address authentication scheme to prevent unauthorized access. I am working on mapping the campus out similar to what was done at Kansas for a networking class, has anyone worked much with GIS programs, or is in the boulder area.
