  26. 26. Basic Requirements and Features: “IMT-2000 defines third generation mobile systems which are scheduled to start service around the year 2000 … These systems will provide access by means of one or more radio links to a wide range of telecommunications services supported by the fixed and mobile telecommunications networks (e.g. PSTN/ISDN/PLMN), and to other services which may be unique to IMT-2000. A range of mobile terminal types designed for mobile and fixed use, is envisaged linking to terrestrial and/or satellite-based networks.” 1997 ITU Circular Letter
  27. 27. Basic Requirements and Features: “A goal for third generation mobile systems is to provide universal coverage and to enable terminals to be capable of seamless roaming between multiple networks … It is a design objective of IMT-2000 that the number of radio interfaces should be minimal and, if more than one interface is required, that there should be a high degree of commonality between them.” 1997 ITU Circular Letter
