Technical Details
The VX7000 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.
