Technical Details
The LG 8500 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.
