4G Vision and Technology Development in Korea

초록

With increasing end user demands for wider service due to the rapid growth and variety of IT (information technology) industry, the service with the data rate of 30Mbps cannot accommodate the future mobile multimedia environment. Therefore, worldwide radio and mobile communication institutes and companies started the R & D of 4G mobile communications system prior to completing the implementation of IMT-2000 system and providing its service. ETRI is one of those organizations endeavoring for the future 4G system with capabilities beyond IMT-2000. With the establishment of R&D project for 4G radio transmission system in January of 2002, ETRI is actively working to develop 4G high-tier system, HMM(High-speed Mobile Multi-media), and 4G low-tier systems, HMI(High-speed Mobile Internet), and HPi(High-speed Portable Internet). In this paper, ETRI’s 4G vision and enabling technologies to achieve this vision is described.
