Technical Details
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 PCS CDMA Networks consist of MSO
(Mobile Switching Office), BSC (Base
Station Controller), BTS (Base Station
Transmission System), and MS (Mobile
Station).
* 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. Highspeed
data transmission is also possible.
The following table lists some major CDMA
standards.
FCC RF Exposure Information
WARNING! Read this information before
operating the phone.
In August 1996, the Federal
Communications Commission (FCC) of the
United States, with its action in Report and
Order FCC 96-326, adopted an updated
safety standard for human exposure to
Radio Frequency (RF) electromagnetic
energy emitted by FCC regulated
transmitters. Those guidelines are
consistent with the safety standard
previously set by both U.S. and
international standards bodies. The design
of this phone complies with the FCC
guidelines and these international
standards.
