Welcome

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 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.
