Technical Details
The Rumor Touch 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
Its battery life is twice as long as IS-95.
High-speed data transmission is also
possible.
The following tab lists some major CDMA
standards.
