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

Technical

compared with analog mode. In addition, features

reduce call interruptions.

 

such as soft / softer handoff, hard Handoff, and

dynamic RF power control technologies combine to

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.
