This chapter describes evolving priority and precedence in commercial wireless systems, beginning with the Final Report of the Public Safety Wireless Advisory Committee (PSWAC) statement of needs. The chapter describes the Global System for Mobile (GSM) and, most importantly, the Enhanced Multi-Level Precedence and Preemption capability. GSM is shown to provide the MLPP capability needed in the US after 9–11 to provide priority services for National Security and Emergency preparedness subscribers.
