CDMA2000 1X (IS-2000), also known as 1x and 1xRTT, is the core CDMA2000 wireless air interface standard.The designation "1x", meaning 1 times radio transmission technology, indicates the same radio frequency (RF) bandwidth as IS-95: a duplex pair of 1.25 MHz radio channels. 1xRTT almost doubles the capacity of IS-95 by adding 64 more traffic channels to the forward link, orthogonal to (in ...

The Qualcomm standard IS-2000, known as CDMA2000, is used by several mobile phone companies, including the Globalstar network. [nb 1] The UMTS 3G mobile phone standard, which uses W-CDMA. [nb 2] CDMA has been used in the OmniTRACS satellite system for transportation logistics.
In 3G, the most prevalent technology was UMTS with CDMA-2000 in close contention. All radio access technologies have to solve the same problems: to divide the finite RF spectrum among multiple users as efficiently as possible. GSM uses TDMA and FDMA for user and cell separation. UMTS, IS-95 and CDMA-2000 use CDMA. WiMAX and LTE use OFDM.

This was later changed to 6 half rate time slots for more compressed calls. It was once prevalent throughout the Americas, particularly in the United States and Canada since the first commercial network was deployed in 1993 on AT&T and Rogers Wireless Networks. IS-95 was the first ever CDMA
