Technical Details
The LG COSMOS
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).
