Personal Communications Services
Служба персональной связи
термин, используемый FCC для обозначения набора технологий цифровой мобильной связи. В частности, включает в себя CDMA (IS-95), GSM и IS-136. PCS служит также для передачи коротких сообщений и пейджинга. Использует диапазон частот 1850-2200 МГц, обеспечивает скорость передачи от 4,8 до 28,8 Кбит/с. С 1995 г. FCC выдаёт лицензии на использование PCS-систем. Этот диапазон поделён на блоки (с А по F), которые предназначены для разных рынков. В частности, два больших 30 МГц блока (А и В) выделены для систем в больших городах (так называемые Major Trading Area). В дополнение к 120 МГц диапазону лицензируемого спектра две полосы по 10 МГц (одна для голоса, другая для данных) предназначены для нелицензируемых применений
