Cellular communication is a form of wireless communication that enables
several key concepts to be employed:
The cellular concept is employed in many different forms. The term
cellular communication is typically applied to either the AMPS or TACS
technology. The AMPS operating frequency is in the 800 MHz band: 821 to
849 MHz for the base station receiver and 869 to 894 MHz for the base
station transmitter. For TACS the frequency range is between 890 MHz and
915 MHz for the base receiver and 935 MHz and 960 MHz for the base station
transmitter. Many other technologies also fall under the guise of
cellular communication, including those involving the PCS bands-both the
domestic and the international bands. In addition, because the same
concept is applied to several technology platforms that are currently used
in the SMR band (IS-136 and iDEN), the term cellular communication
sometimes is used to describe these as well. However, cellular
communication usually refers specifically to the AMPS and TACS bands. |
