Technical Details

LG 380 is an all digital phone that
operates on both Code Division
Multiple Access (CDMA)
frequencies: cellular services at 800
Mhz and Personal Communication
Services (PCS) at 1.9 Ghz.
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.
* TSB -74: Protocol between an IS-
95A system and ANSI J-STD-008
Technical Details
1xRTT system receives twice as
many subscribers in the wireless
section as IS-95. Its battery life is
twice as long as IS-95. High-speed
data transmission is also possible.
