Worlds First Commercial cdma2000 1X Service Imminent

In the fourth quarter of 2000, SK Telecom aims to launch cdma2000 1X service, which at 144Kpbs will provide much faster wireless data transmission than the current IS-95A (9.6Kbps) or IS-95B (64Kbps) systems. Jong-yong Yun, Vice Chairman & CEO of Samsung Electronics Co., Ltd. and Jung-nam Cho, President of SK Telecom officially signed a cdma2000 1X system supply contract which is worth of USD 200 million at the Shilla Hotel on May 3. SK Telecom and Samsung Electronics exchanged MOU for the system development in August 1998. Filed trials were conducted at the Samsung Electronics Bundang Research Center last November, ending in the world's first successful test call completed between a system manufacturer and a service provider on an cdma2000 1X system. That test confirmed the possibility of deploying commercial cdma2000 1X service in the near future. The cdma2000 1X system is capable of fast wireless data transmission and can support interactive video service. It is completely compatible with the current IS-95A and IS-95B systems and can simultaneously provide audio, video and text data services, making it the best wireless multimedia solution developed so far. The supply contract between SK Telecom and Samsung Electronics will enable SK Telecom to start up commercial operation of an cdma2000 1X system ahead of the competition. This will mean that the company can offer the world's best wireless data services. The two companies have also agreed to cooperate in overseas projects related to consulting services, operation, maintenance and system supply. This arrangement will give them an advantage in providing the cdma2000 1X system to the world wireless communications market. The Samsung system will cover most of Korea peninsula including the Seoul metropolitan area and mid provinces. The cdma2000 1X system to be supplied to SK Telecom includes base station modem chipsets developed exclusively by Samsung Electronics, boosting the level of Korean wireless communication technology and the stature of Korean telecommunications companies. Samsung Electronics has also worked to improve the international competitiveness of Korean companies by submitting a number of standardization proposals regarding the cdma2000 to international standards institutions. The cdma2000 1X system to be launched by SK Telecom in the fourth quarter of 2000 is one of the standards being considered for IMT-2000. Thus, most of the hardware will be applicable for IMT-2000 service, so industry insiders say this will support the government's selection of IMT-2000 service providers. Background: What is cdma2000 1X cdma2000 1X is capable of offering wireless data services at up to 144Kbps, and it can easily provided over the same frequency band as conventional services. The 1.25M band is the same used by IS-95A/B. In addition to being faster, cdma2000 1X sends and receives data in packets. Therefore, when no data is being transmitted, the wireless channel can be allocated to other users, enhancing the efficiency of wireless resource use. By contrast, the other systems adopt a circuit approach when receiving data services. This means that the wireless channel is occupied even when no data are being transmitted. Finally, cdma2000 1X has twice the wireless channel capacity of the IS-95A/B systems. Therefore, the same frequency band can accommodate at least double the traffic when the cdma2000 1X system is used.
