The LG-5450 is a tri-mode phone that operates on
both Code Division Multiple Access (CDMA)
frequencies of 800 MHz Cellular and 1.9 GHz
Personal Communication Services (PCS) as well as
800 MHz Analog service.
CDMA technology uses a feature called DSSS
(Direct Sequence Spread Spectrum) that enables the
phone to keep communication from being crossed
and to use one frequency channel by multiple users
in the same specific area. This results in a 10-fold
capacity increase when compared with analog mode.
In addition, features such as soft / softer handoff,
hard Handoff, and dynamic RF power control
technologies combine to reduce call interruptions.
The Cellular and PCS CDMA networks consist of
MSO (Mobile Switching Office), BSC (Base Station
Controller), BTS (Base station Transmission System),
and MS (Mobile Station). The following table lists
some major CDMA standards.
