The phone has been designed to operate on the latest
digital mobile communication technology, Code Division
Multiple Access (CDMA). This CDMA digital technology
has greatly enhanced voice clarity and can provide a
variety of advanced features. Currently, CDMA mobile
communication technology has been commercially used
in Cellular and Personal Communication Service (PCS).
The difference between Cellular and PCS is operating
frequency. Cellular uses 800Mhz and PCS uses 1.9Ghz.
Also, the VX2000 works on Advanced Mobile Phone
Service (AMPS). We call it a tri-mode phone. Since the
phone operates on Cellular, PCS and AMPS, the call fail
rate is less than on a conventional dual-mode or single-
mode phone.
CDMA technology adopts DSSS (Direct Sequence
Spread Spectrum). DSSS enables the phone to keep
communication from being crossed and to use one
frequency channel by multiple users in the same specific
area, resulting in a 10 fold increase in capacity when
compared with the analog mode currently used.
Soft/Softer Handoff, Hard Handoff, and Dynamic RF
power Control technologies are combined into this
phone 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.
