Personal communications networking architecture and functionality evolution

The evolving personal communications network (PCN) will support services beyond mobile cellular telephony through the availability of personal communications terminals, which can be used in the home, in the office, or elsewhere.

An overview of PCN architectures, PCN applications, and functionality evolution is given
