Technical Details
The VX6100 is a tri-mode phone (1.9 GHz CDMA, 800 MHz
CDMA/AMPS) that operates on both Code Division Multiple
Access (CDMA) frequencies: cellular services at 800 MHz and
Personal Communication Services (PCS) at 1.9 GHz. Also, the
VX6100 works on Advanced Mobile Phone Service(AMPS).
CDMA technology uses a feature called DSSS (Direct Sequence
Spread Spectrum) that enables the phone to keep communica-
tion 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 addi-
tion, 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 fol-
lowing 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 wire-
less section as IS-95. Its battery life is twice as long as IS-95.
High-speed data transmission is also possible.
