Migration to IMT-2000 Systems

Handbook. Supplement 1 (Revision 1) Deployment of IMT-2000 Systems

This revised Supplement expands on the first edition of the ITU Handbook - Deployment of IMT-2000 Systems and updates much of the work that has occurred since the release of the Handbook. It addresses the subject of evolution and migration from current mobile systems towards IMT-2000. ITU-R has developed this work in response to ongoing liaison and interaction with the ITU-D and ITU-T Sectors and sees this material as the natural extension of the information presented in the Handbook.

Concluding remarks

This revised Supplement 1 to the Handbook offers additional information and guidance to operators and administrations on the radio aspects associated with the evolution/migration of pre-IMT-2000 systems to IMT-2000 systems. It makes use of further studies and the experience that has been gained since the Handbook was published. The Supplement illustrates that the net effect of the gradual substitution of pre-IMT-2000 systems with IMT-2000 systems worldwide will be the result of the combination of substitution processes in many countries where local conditions and investment policies will determine the actual path taken and, ultimately, the speed of the transition.
