Abstract :
The author predicts at least four major stages in the evolution of personal communication services (PCS). Stage one will include isolated PCS islands/experiments proprietary technologies, some dedicated or shared frequency spectra and limited services. Stage two will include limited interoperability, initial industry coalitions, some dedicated or shared frequency spectra, and more services. Stages one and two cover the period 1992-2000. Stage three will include widespread interworking, stable spectrum assignments, broad industry coalitions, personal numbers, and standard services. Stage four includes adequate spectrum/capacity, national interfaces, stable industry structure, widespread personal numbers, and mass-market services. Stages three and four cover the period 2000-2005.<>
