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."

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.
