Technical Details
The AX300 is a trimode 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
10
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).
