Technical Details
The LG Vortex
TM
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 1xRTT system receives twice as many subscribers in the
wireless section as IS-95. Benefits from using 1xRTT instead of IS-
95 include extending your device's battery life (up to twice as long)
and high speed data transmission capability. However, in applicable
areas, EV-DO system is optimized for data service and therefore is
much faster than 1xRTT.
The table on the following page lists some major CDMA standards.
