Technical Details

The LG 8100 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
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.
