Technical Details
The AX8600 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).
* 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.
The following table lists some major CDMA
standards.
