Technical Details
The
Chocolate
®
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
incr
ease 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. 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 table on the following page
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
int
ernational standards bodies. The
design of this phone complies with
the FCC guidelines and these
international standards.
Bodily Contact During Operation
This device was tested for typical
use with the back of the phone
kept 0.79 inches (2.0 cm) from
the body. To comply with FCC RF
exposure requirements, a minimum
separation distance of 0.79 inches
