  • Shared hub VSAT service in Canada

    Publication Year: 1992, Page(s):1/1 - 10/4

    The authors discuss the use of wide area diversity (WAD) in conjunction with very small aperture terminals (VSATs) connected to metropolitan area networks (MANs). Metropolitan area networks can provide very high speed data paths and may soon cover cities and other built up areas. Such networks can be linked by satellites, which are inherently capable of high data rates, and can link areas not conn... View full abstract»

    At some level of service requirement it is necessary to adopt a multiple beam satellite antenna concept, since wide coverage coupled with high bit speeds and small Earth stations leads to impossible requirements in the satellite. On the other hand using multiple beams has a negative impact on the interconnectivity of the small Earth stations. The author tries to throw some light on the issues whic... View full abstract»

    Given the monopolistic market structure of the telecommunications industry in Europe, the commercial success of VSAT's hinges not only on future developments in the engineering of the technology, but as the author argues, is also inextricably linked to the pace and degree of market liberalization as observed in the United States. The author outlines some of the market regulatory issues in Europe w... View full abstract»

    The initial development of VSAT and data broadcast systems in the US and in Europe has been directed towards financial services information providers where the principal application is delivering information to customers. One of the first operational services was the Telekurs Advanced Quotation (TAQ) service developed by Telekurs UK, part of the Swiss financial institution Telekurs AG. The system ...

    The authors discuss the background and requirements for a portable radio broadcast satellite VSAT; stereo capability; high portability; a talkback channel; one man operation; easy operation; and a closed network architecture. The resulting SATSOUND equipment is described. It consists of a control station, a fixed Earth station and a portable terminal.<<ETX>> View full abstract»

    The author discusses the growth in demand for live television news and sport. Several forms of SNG satellite ground stations are examined: 1.5 m flyaway ground station; mobile terminals for estate cars; and mobile vans. FM equipment is compared to compressed digital TV equipment, and the link budget is given.<<ETX>> View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (287 KB)

    The author discusses a low data rate mini SCPC multi-point to point network of C-band VSAT's located within a global footprint for monitoring, control and data acquisition applications with a hub in UK. This VSAT data network is characterised by lower operating costs compared with conventional private circuits and packet switching services. Obtaining a licence to operate the remote VSATs is the ke... View full abstract»

    Four applications of VSATs relevant to banking are considered: automated teller machines; credit card verification; simultaneous common database update; and voice/fax communication. In each of these applications VSATs can offer important advantages in providing the required telecommunications medium. A short discussion of the interfacing facilities required for data networking is included and fina... View full abstract»

    In general, the VSAT system architecture lends itself more readily to standalone private networks. However, very few organisations are of a size that can justify a dedicated corporate VSAT network. Telesat saw an opportunity to employ its considerable experience in satellite communications to provide a shared-hub VSAT service in Canada and in so doing established the world's first commercial share...
