Technology Evolution of CDMA 2000 1x

Code Division Multiple Access (CDMA) system is first time launched commercially in the year 1989 by Qualcomm in United States. This System better than the predecessor of that is system of Advanced Mobile Phone System (AMPS). CDMA system can improve customer capacities and improve the quality of voice. CDMA system is second generation (2G) in communications of wireless.

CDMA2000 also known as IMT-CDMA Multi-Carrier or IS-2000, which evolution growth of technology CDMA One / IS-95 next to third generation services for operators CDMA on the cellular network. Cellular network with this technology applied and developed in like Japan state, and some states in south-east Asia like Indonesia.

Code Division Multiple Access (CDMA) technology is one of alternative architecture GSM cellular. That second of the technology make transition to third generation system (3G) offered more capacities service and data service. 2000 CDMA this experience of some growth phases, first phase is CDMA 2000 1x or recognized by 1x Radio of Transmission Technology (1x-RTT) which owning speed of mean data transfer equal to 144 kbps for to peripatetic condition. The second phase for the growth of CDMA 2000 is 1x EV-DO (1x Evolution Data Only) owning speed of data very high at data dedicated carrier. Third phase Technological is 1x EV-DV (1x Evolution Data / Voice) owning speed data of reach 3 Mbps for the data packet and voice.

Technology CDMA 2000 1x EV-DV extends developed final in the year 2003 until now of integrating technology before data packet and voice. As mean to give more service either from at first technology. System 2000 1x EV-DV will give speed of data deliverance and high voice by successive also accompany package service by real time. Figure 2.1 showing evolution systems of CDMA 2000.
