A wireless information network (WIN) is undergoing development for use by workers at locations scattered across Kennedy Space Center (KSC). This WIN could be a prototype of a larger network that would serve all of NASA; by logical extension, it could also be a prototype of commercial WINs. By use of a combination of commercial hardware and custom software, this WIN would give KSC personnel access to the main KSC information systems, electronic mail, and other productivity-enhancing computational capabilities. The software includes the IPSWITCH application program, which is compatible with the Windows 3.1, 95, and NT operating systems. IPSWITCH enables the user to store several network-configuration profiles for a computer work station, making it possible to reconfigure the computer rapidly to operate on different subnetworks. When the user starts the execution of IPSWITCH under Windows, the program generates an interactive display, through which the user can create, edit, and save five different Internet Protocol (IP) configurations for each subnetwork interface.
