Everything about Personal Communications Service totally explained
Personal Communications Service or
PCS is the name for the 1900-
MHz radio band used for
digital mobile phone services in
Canada,
Mexico and the
United States.
Code Division Multiple Access (CDMA),
GSM, and
D-AMPS systems can 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 824-894 MHz was becoming overcrowded.
Dual-band GSM phones are capable of working in both the 850- and 1900-MHz bands, although they're incompatible with 900- and 1800-MHz European and Asian systems. However, GSM "world phones" (some of which are known as
tri-band or
quad-band phones, because they operate in three or four different frequency bands, respectively) offered by North American carriers support both European and domestic frequencies. Outside the USA, PCS is used to refer to
GSM-1900. In
Hong Kong, PCS is used to refer to
GSM-1800.
Sprint was the first company to set up a PCS network, which was a GSM-1900 network in the
Baltimore-Washington metropolitan area in the USA. Eventually however, Sprint converted that network to CDMA technology and sold the GSM infrastructure to Omnipoint, which later became part of
T-Mobile USA. Nowadays, the PCS frequencies have been adopted for usage in most parts of the
Americas.
