Technical Details
The VENUS™ 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.
EV-DO system is optimized for data
service and is much faster than
1xRTT system in applicable area.
The following table lists some major
CDMA standards.
