WITS - A Coaxial Cable Bus Network for Medical Applications

摘要

Walter Reed ARMY Medical Center has been serving as a Army test bed for coaxial cable-based local area networks since early 1978. This particular network, called the WRAMC Information Transfer System (WITS), carries commercial television, FM radio, closed-circuit TV and maintenance intercom audio, as well as digital data.The technology has proven successful. Broadband coaxial cable systems provide an opportunity to realize communications architectures that are flexible, highly reliable, and inexpensive. They are particularly appropriate for use in medical facilities where applications change over time and when many and varied systems are required to interact together.
