    The very-small-aperture-terminal (VSAT) fixed satellite communication network is a star network in which many dispersed micro terminals attempt to send data in a packet form through a random access/time-division multiple-access (RA/TDMA) satellite channel with transmission delay. The basic concept of the VSAT and its service potential are discussed. Two classes of traffic are addressed, namely bus... View full abstract»

    A critical parameter of a very small aperture terminal (VSAT) satellite network, namely the availability of its links, is defined as the percentage of time that information can be transmitted and received with acceptable quality. The information quality is quantified, and the factors that affect it are described. Link unavailability (outage) due to equipment problems and rainfall is discussed. The... View full abstract»

    The performance of candidate protocols for first-generation Ku-band very small aperture terminal (VSAT) satellite networks is compared. The goal is to assist the process of selecting a protocol. The performance comparison is carried out over a range of possible traffic, channel and satellite parameters, leading to an understanding of the appropriate regime for each of the protocols under considera...

    A description is given of a low-cost telephone-based information terminal that not only retains the characteristics of a telephone as a convenient vehicle for an individual's information but also can handle nontelephone media in a future local information system. It is essentially a hands-free telephone with a flat display panel and an overlaid electronic writing tablet, but no keyboard. Features ... View full abstract»
