LG LG535, User Manual

Page: 9 / 161

Technical Details
The LG 535 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. Also, the LG 535 works on Advanced Mobile
Phone Service (AMPS). We call it a tri-mode phone. Since the
phone operates on Cellular, PCS and AMPS, the call fail rate is
less than on a conventional dual-mode or singlemode phone.
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.
