Abstract	This study presents cross-correlation of building density in outdoor environments for fifth generation mobile communications at 781 MHz. To avoid interference from Korean digital television (DTV) broadcasting, the authors measured the radio characteristics on Jeju Island using a channel sounder and four-by-four antennas. They derived basic large-scale parameters (LSPs) such as path loss, delay spread, angular spread, and Rician K-factor from eight different sites. The real building standing area was estimated with a geographic information system database. They propose an empirical model from analysis of the correlations between LSPs and building density. This model indicates that building density is not determined by measurement scenario such as urban, suburban, and rural. The proposed model only reflects change in building density for an outdoor environment. Finally, they verify their model through ray-tracing simulation similar to a real environment. This model can be useful in the design of future mobile communications systems according to changes in building density.
