Technical Details
The Ellipse 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
12
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).
1xRTT system receives twice as
many subscribers in the wireless
