CMU researchers are developing a set of design methods and tools to help builders of wireless, local area "Wi-Fi" (802.11) networks insure high speed, reliable service. Wi-Fi allows users of laptop and handheld computers to move around while connected to the Internet at high speeds.
Scientists at CMU have also introduced "Rollabout," a new rolling cart tool that automatically collects data from a number of access points (base stations) to ultimately determine the bandwidth needed by the user community. Rollabout speeds up the layout process, and removes guesswork from the design process, allowing businesses to build cheaper, more reliable wireless networks.
