At the most basic level
Personal Communications Service or
PCS describes a set of
wireless communications capabilities which allows some combination of terminal mobility,
personal mobility, and service profile management. More specifically, PCS refers to any of several types of wireless voice and/or wireless data communications systems, typically incorporating digital technology, providing services similar to advanced
cellular mobile or
paging services. In addition, PCS can also be used to provide other wireless communications services, including services which allow people to place and receive communications while away from their home or office, as well as wireless communications to homes, office buildings and other
fixed locations. Described in more commercial terms, PCS is a generation of wireless-phone technology that combines a range of features and services surpassing those available in analog- and digital-cellular phone systems, providing a user with an all-in-one wireless phone, paging, messaging, and data service.
