CDMA450 - CDMA at 450 MHz - basics of CDMA450 or CDMA 450
versions of CDMA2000 1X and 1X EV-DO used in the 450 MHz
cellular band. See also the other cdmaOne / CDMA2000 tutorials:
IS-95 / cdmaOne  CDMA2000 1X  CDMA2000 1xEV-DO CDMA450 is a form
of CDMA2000 that operates across the 410 - 470 MHz cellular
band. This band is often referred to as the 450 MHz band, and
this gives rise to the name, CDMA450. The CDG - CDMA Development
Group state that CDMA450 is the only 3G (IMT-2000) solution that
is commercially available for deployment in the 450 MHz
frequency band. CDMA450 is a generic name for all the CDMA
systems that use the 450 MHz band - all the standards published
by the TIA as TIA-EIA-IS-CDMA2000. As such, the CDMA450 system
includes the following CDMA systems: - CDMA2000 1X - 1X EV-DO
Release 0 - 1X EV-DO Revision A - 1X EV-DO Revision B - Any
future enhancements to these technologies Often the CDMA2000 1X
and EV-DO services run alongside each other, but using different
carriers. In this way both voice an
