2): This is most pronounced in the equatorial regions of the world (particularly along the geomagnetic equator). Like Faraday rotation, this source of fading decreases with increasing frequency, making it a factor for L-, S-, and C-band links. 01%. , above 7 GHz), rain introduces a substantial amount of loss that must be taken into account in the link design. Regions with intense thunderstorm activity, particularly in the tropics, tend to complicate link design at Ku-band and above, and offer some challenge at C-band as well.
Some of the must successful users of VSATs are familiar names in North American consumer markets. S. department store chain, which has opened outlets in Europe, Latin America, and China, was an early adopter of the technology and has pushed its competitors to use VSATs in much the same manner that they pioneered the megastore. With their Earth station hub at the Arkansas headquarters, Wal-Mart centralizes its credit authorization and inventory management functions. Chevron Oil likewise was first among the gasoline retailers to install VSATs at all of their company-owned filling stations to speed customer service at the pump, prevent fraud, and gain a better system-wide understanding of purchasing trends.
This is a subset of the general principle of competitive strategy as outlined by Michael E. Porter in his seminal book of the same title . A data communication system is really only one element of an architecture that is intended to perform business automation functions. However, defining the right 24 Evolution of Satellite Technology and Applications architecture and putting the associated hardware, software, and network pieces in place is often a tall order. As cited previously, major corporations have found that a properly designed and managed satellite data network can overcome some of the most challenging difficulties in this area.
