The first phase of CDMA2000 offering voice and data services. Peak data rates of 307 kbps can be achieved using a single channel and when two are used this increases to 614 kbps.
Cdma2000 1x, the next generation of CDMA, supports between 1.5 and 2 times the number of voice channels as a standard CDMA system as well as 144-Kbps packet-data services. Cdma2000 1x is 21 times more efficient than analog cellular and 4 times more efficient than TDMA networks. (Cdma2000 1x data speeds will increase from 144 Kbps to 288 Kbps by the end of 2002.)
A 3G technology which provides voice and data capabilities within a standard 1.25 MHz CDMA channel for outstanding spectral efficiency and flexibility. CDMA2000 builds on earlier CDMA technology (known as cdmaOne) to provide a simple evolution to 3G services. It nearly doubles voice capacity over second-generation CDMA networks and supports high-speed data services.
A set of specifications offering enhanced voice capacityover CDMAOne and increased peak data speeds of up to 2Mbps. The specifications include 1xRTT (RadioTransmission Technology), 1xEVDO (evolution¡ªdata only)and 1xEVDV (evolution¡ªdata and voice).
First step in the evolution to 3G, which improves packet data transmission capabilities and speeds in the network, and also boosts voice capacity by nearly two times over today's CDMA capacities. CDMA2000 1xEV represents the second step in the evolution of CDMA2000 and will bring data rates of up to 2Mbits/s to the network.
The first step in the evolution to 3G is cdma2000 1X, which improves packet data transmission capabilities and speeds in the network, and also boosts voice capacity by nearly two times over today's CDMA capacities. Speed of upto 144kpps.
a.k.a. 1X, 1XRTT, CDMA2000 A family of third-generation (3G) wireless standards that offers enhanced voice and data capacity and higher data rates than previous, second-generation wireless standards. The CDMA2000 family of standards includes CDMA2000 1X and CDMA2000 1xEV-DO. CDMA2000 is a direct evolution of cdmaOne®. See Also: IS-2000, IMT2000
A 3G wireless communications standard evolved from CDMA technology. It has double the voice traffic capacity of CDMA and provides peak data rates of 153 kbps.
CDMA2000 1X, the next generation of CDMA, supports between 1.5 and 2 times the number of voice channels as a standard CDMA system as well as 144-Kbps packet-data services. CDMA2000 1X is 21 times more efficient than analog cellular and 4 times more efficient than TDMA networks. Typical CDMA2000 1X data throughput is 60 to 80 kbps on a loaded network.
A 3G technology which provides voice and data capabilities within a standard 1.25 MHz CDMA channel for outstanding spectral efficiency and flexibility. CDMA2000 builds on earlier CDMA technology (known as cdmaOne) to provide a simple, seamless evolution to third-generation services. It doubles the voice capacity of cdmaOne systems and also supports high-speed data services.
Commonly referred to as 1X or 1XRTT, CDMA2000® 1X is a 3G technology that is commercially available today. The first evolution from its cdmaOne predecessor, 1X is 21 times more efficient than analog cellular and 4 times more efficient than TDMA networks. Typical 1X networks provide peak rates of 144 Kbps for packet data and provide an average throughput range of 60-80 Kbps on a loaded network.
CDMA2000 is synonymous with 3G pertaining to wireless networks. 1x is the first phrase of implementation of a 3G CDMA based cellular network and offers about twice the capacity of current exsisting 2G networks, with data transfer rates of 144kps. CDMA2000 1x is backwards compatible with exsisting CDMA networks, and sends and receives data in packets. It allows the data channel to be allocated to other users if there is no data being transmitted, and therefore makes the network more efficient.
