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

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.
EV-DO system is optimized for data
service and is much faster than
1xRTT system in applicable area.
The following table lists some major
CDMA standards.
