operated the equipment under
FCC rules.
Technical Details
The device 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.

Part 15.105 statement
This equipment has been tested
and found to comply with the
limits for a class B digital device,
pursuant to Part 15 of the FCC
rules. These limits are designed
to provide reasonable protection
against harmful interference in
a residential installation. This
equipment generates, uses, and
can radiate radio frequency energy
and, if not installed and used in
accordance with the instructions,
may cause harmful interference
to radio communications.
However, there is no guarantee
that interference will not occur
in a particular installation. If
you experience interference
with reception (e.g., television),
determine if this equipment is
causing the harmful interference by
turning the equipment off and then
back on to see if the interference
is affected. If necessary, try
correcting the interference by one
or more of the following measures:
