Technical Details

The VX3100A is a tri-mode 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.
Also, the VX3100A 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 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.
