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
Details	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.
