Multipath Delay Characteristic in mm-Wave Radio Propagation in Indoor Public Area

摘要

This paper describes root mean square delay spread as the large scale factor based on multipath signals measurement in indoor commercial environment at both 28 and 38GHz. The mm-Wave measurement has been performed in the public regions of both the international airport terminal and railway station, which were chosen to represent the indoor small cell areas in South Korea. We found that the distribution of the cumulative density function of root mean square delay spread in the large and small scale is dependent on the frequency in indoor public area.
