Personal Communications Service or PCS is the name for the 1900-MHz radio band used for digitalmobile phone services in Canada and the United States. CDMA, GSM, and TDMA systems can all be used on PCS frequencies. The FCC, as well as Industry Canada, set aside the frequency band of 1850-1990 MHz for mobile phone use in 1994, as the original cellular phone band at 824-849 MHz was becoming overcrowded. Dual-band phones are capable of working in both the 800- and 1900-MHz bands, although they are incompatible with 900- and 1800-MHz European systems. However, "world phones" (some of which are known as "tri-band" phones, because they operate in three different frequency bands) offered by American carriers support both European and domestic frequencies. Outside the USA PCS is used to refer to GSM-1900. MegaHertz (MHz) is the name given to one million (106) Hertz, a measure of frequency. ...

Personalcommunicationsservice is defined more formally as "a set of capabilities that allows some combination of personal mobility, terminal mobility, and service profile management.
It enables each personalcommunicationsservice user to participate in a user-defined set of subscribed services and to initiate and/or receive calls on the basis of some combination of a personal number, terminal number, and service profile across multiple networks at any terminal, fixed or mobile, irrespective of geographic location.
Depending on the service provider, calls could be charged to the calling party, the called party, or some combination of both.
In a communication network, as in claim 34, wherein at least one of the service switching means comprises a telephone central office switching system connected to a plurality of telephone lines, and the registering step is performed by transmission of registration data over one of said telephone lines.
In a communication network, as in claim 37, wherein at least one of the service switching means comprises a telephone central office switching system connected to a plurality of telephone lines, and the registering step is performed by transmission of registration data over one of said telephone lines.
The mobile communication unit, particularly when in the form of a handset, is configured in manner similar to the cordless handsets found in the prior art, except that the PCS units include a radio transceivers operating at cellular frequencies and capable of meeting cellular signalling protocols.
