Technical Details
The VX4600 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). 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.
