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
