CDMA2000

Enhancements to the CDMA cellular technology that increase the number of users on a voice circuit and provides high-speed packet data. In 2000, CDMA2000 was the first 3G technology to be deployed as part of the ITU's IMT-2000 framework (see IMT-2000). By 2009, the CDMA Development Group (CDG) reported more than 440 million CDMA2000 subscribers worldwide.

CDMA2000 1x
The first version of CDMA2000 enables up to 100 callers to share a single 1.25 MHz CDMA channel and provies a peak data rate of 153 Kbps. The use of the single channel is known as "1X" or "1xRTT" (1x Radio Transmission Technology). 1X has also been known as "IS-2000," "MC-1x," and "IMT-CDMA MultiCarrier 1x."

CDMA2000 EV-DO
Evolution-Data Optimized (EV-DO) technology increased the peak data rate first to 2.45 Mbps and later to 3.1 Mbps per channel, with the average user experiencing from 500 to 800 Kbps. For more details, see EV-DO. See CDMA, CDMA450, WCDMA, LTE and cellular generations.


1X Signal Strength
The "1X" is the 1xRTT signal strength on this cellphone, which is only one bar at this moment. The "EV" signal, also one bar, is the EV-DO channel. As the phone travels, the strength of the two signals may differ.

The module is equipped with CDMA tri-mode capability (including AMPS), A-GPS position location capability and support for IS-2000 data rates (153KBps on forward and reverse links).
It supports both 800 MHz and 1900 MHz bands as well as AMPS and complies with IS-2000 protocol stack for voice calls, SMS, data services, including fax, GPS, with AT command set.
In addition, 1xEV-DV is backward compatible with the IS-2000 1X and IS-95 standards, therefore the TBB5160 processor implements all the functions, such as voice encoding and decoding, system control and high-performance digital signal processing, for compliance with both standards.
TI's dual-processor TBB5110 digital baseband communications engine provides voice encoding and decoding, system control and high-performance digital signal processing of both IS-95 and IS-2000 1X CDMA supporting IS-2000 Revision 0 data rates up to 153.
It will also enable baseband processors designed to meet or exceed the specifications of mobile stations for worldwide 3G CDMA systems as specified by IS-2000 standards.
