A study of 2.3 GHz bands propagation characteristic measured in Korea

The WLL (wireless local loop) service at the 2.3 GHz frequency band is being withdrawn and redistributed as a new service for efficient use of radio resources in South Korea. In this paper, analysis of 2.3 GHz band propagation path loss characteristics by investigating the raw data gathered from practical measurements is presented. Also, we have performed field measurement in the frequency band over several types of building to obtain the penetration loss and diffraction loss. 2.3 GHz band propagation characteristics (path loss, diffraction loss, and penetration loss) and a corrected theoretical model for path loss prediction which was presented will be useful to applications such as prediction of path loss in the consideration of domestic environments, cell planning and optimization for new service systems.
