Introduction of 4G Activities in Korea

In Korea, the development of 4G mobile system technologies is very actively carried on. The activities of 4G development in Korea will be introduced in this paper. In the first part, the current status of preparing the commercial WiBro service will be presented. The WiBro Service (Portable Internet Service for 2.3GHz), as the low mobility data service, has been defined as a pre-4G service and the development of the system for 30 ~ 50Mbps is on the way for deploying the commercial service in 2006. In the second part, the direction of the technology development for the 4G mobile system will be introduced. The 4G system will support 100Mbps data rate for high mobility and 1Gbps for low mobility based on the ITU-R recommendation. In the last part, various collaborative activities in Asia area, such as the NGMC forum in Korea and CJK collaboration, will be introduced in the paper.
