    An attempt is made to characterize intelligent buildings and to describe them in simple system terms. The services provided by the various building communications subsystems are examined, and the role played by the internal building communications system, which may be regarded as the building's nervous system, is shown. Some examples of intelligent buildings are examined.<> View full abstract»

    The principal issues faced in intelligent building design and construction are presented. The components of the intelligent building are placed into four main categories-facilities management, information management, connectivity, and overall control-and each of these is examined. Multitenant shared services, the changing nature of building components, and the benefits of intelligent building mana... View full abstract»

    The role of the telecommunications systems in intelligent building telecommunication technology is described, focusing on trends in Japan. The capabilities of private branch exchanges (PBXs) are examined, local area networks (LANs) are considered, and possible architectures for a backbone network are described. The building wiring issue is addressed, stressing the need for a topology accommodating... View full abstract»

    Design issues for intelligent buildings are examined from the viewpoint of the Japanese construction industry. Cultural considerations for such buildings are discussed, with emphasis on the creation of amenities for the human occupants of the building. The need for an infrastructure that is adaptable to future needs is stressed. As an example, a recently built office tower is described.<> View full abstract»

    A wireless in-building network is proposed, raising the possibility that at least part of the hard-wired infrastructure may no longer be needed. This wireless network is based on the refinement of cellular radio techniques in the 18 GHz range. The basic set of problems this technology addresses is described. These are the minimum performance and features required of a viable in-building wireless t... View full abstract»

    The authors describe how spread spectrum operates and explain why the FCC has allocated several spectral bands for spread spectrum. They examine what is wrong with the spectrum allocations the way they are now. They show who is using and will use spread spectrum and why. In particular, they discuss the use of spread spectrum for mobile cellular communications: the personal communications network; ... View full abstract»
