SK Telecom, World?s First to Develop Core Equipment for IMT-2000
2000.03.22Wireless Network Design & Optimization System? Operating on Geographical Information as Accurate as 1 m in Radius
High-speed Mobile Internet Equipment? Enabling High-volume Data Transmission
First Visible Outcome of the Technical Collaboration with Small- & Mid-sized Companies
A Korean company became the first in the world to develop the core equipment necessary to provide commercial IMT-2000 services.
SK Telecom said that it had become the world?s first to develop ?wireless network design and optimization system CellPLAN? that is essential in building a wireless network to provide IMT-2000 services and ?high-speed mobile Internet equipment? that gives IMT-2000 terminals IP portability, stepping up its efforts to commercialize IMT-2000 services. The company had also made the world?s first call using mobile video phone between Korea and Japan at a successful demonstration last January.
The development of the new equipment is very significant in that it signals the beginning of the flow of tangible outcome of the company?s independent R&D efforts and the collaboration in R&D between SK Telecom and small and mid-sized companies.
SK Telecom held a demonstration of the new equipment at its headquarters on March 22, with the executives of the concerned companies including SK Telecom Vice President Moon Soo Pyo presenting.
? Wireless Network Design and Optimization System CellPLAN
?Wireless Network Design and Optimization System CellPLAN? is a system that allows the operator to design optimal IMT-2000 service areas using computer simulation.
Since it allows analyzing detailed information necessary in service network configuration through simulation, the system helps drastically reduce network-building costs, which account for roughly 80% of the total infrastructure investment for IMT-2000.
In addition, in the case that it is necessary to improve the network as the traffic volume changes due to changes in the environment of the service areas and increases in the user count, the system allows establishing and implementing optimal solutions through simulation in advance and thus optimizing the service quality.
In particular, the system uses geographical information with 1m-in-radius accuracy in the Seoul Metropolitan Area and 10m-in-radius accuracy in the rest of the country, significantly increasing the predictability of the radio frequency usage as opposed to the existing system that uses information with 100m-in-radius accuracy.
SK Telecom already independently developed and is now operating ?wireless network design and optimization system CellPLAN CDMA? for CDMA mobile services, the first in Korea. The company is being contacted for technology transfer or cooperation in R&D by many leading companies outside Korea that recognized SK Telecom?s high R&D capability. The successful development of the new system the company developed using its own CDMA technology means that the company now has proprietary technology essential for building a wireless network for IMT-2000 on top of the economic benefits worth tens of billions of won it would bring through import substitution and export.
The development of the ?wireless network design and optimization system CellPLAN? by SK Telecom is especially significant in that it shows the importance of investing in R&D and developing independent technology, whereas some local companies are highly dependent on foreign products in preparing for the inauguration of IMT-2000 services.
? High-speed Mobile Internet Equipment
SK Telecom?s new ?high-speed mobile Internet equipment? is core component that provides the IMT-2000 terminals with IP portability.
The equipment allows position management of the data flowing in and out of the IMT-2000 terminal. This means that users can receive large volume of packet data using the terminal.
At present, the mobile IP feature necessary for data transmission on the handset terminal is not available and only SMS-based small-capacity data transmission is possible.
The development of the new equipment will allow the delivery of a wide array of multimedia services including video phone and Internet access that supports large capacity data transmission. As a result, IMT-2000 users will be able to freely access existing wireline Internet network using their mobile handsets and enjoy high-speed Internet surfing at 2Mbps.
SK Telecom developed the new equipment in collaboration with Media Link Co. Ltd. (President Jung Yul Ha).
