Technical Details

The Cosmos
TM
Touch 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).
1xRTT system receives twice as
many subscribers in the wireless
section as IS-95. Its battery life is
twice as long as IS-95.
The table on page 11 lists some
major CDMA standards.
