CDMA2000 System

Mobile communication has expanded its service area from voice to data, evolving from the first generation analog mobile communications, to the second generation digital mobile communications and then to the third generation CDMA2000 mobile communications of today.

Especially, with the explosive growth of internet, many people have become interested in high-speed radio transmission technologies required for various multimedia services.

In order to provide these services in today’s internet environment, Samsung has developed the CDMA2000 1X/1xEV-DO system, which is a high-speed radio transmission technology based on the same frequency bandwidth(1.25 MHz) as that of previous technologies, using this technology and onsite experience to be the first to commercialize the CDMA mobile communication service in the world.

Samsung CDMA2000 1X/1xEV-DO systems support voice service, high-speed circuit data service, and high-speed packet data service. Thus, internet services such as web surfing and e-commerce, various contents-providing services such as Video On Demand(VOD) and MP3, and video services including video telephony and video conference can be supported stably and future demands for various multimedia services can be met.

Using the channels of the IS series(e.g., IS-95, IS-2000, and IS-856), the CDMA2000 1X/1xEV-DO systems support backward compatibility for the vocoding, low-speed data service, facsimile service, Short Message Service(SMS), medium-speed data service, handoff functions, which were also provided by the traditional systems.

Samsung CDMA 2000 system provides high-speed multimedia IT services that require various application services as well as voice and data services, and can also be efficiently applied to the migration of mobile communications.
