Propagation Characterization Based on Geographic Location Variation for 5G Small Cells

الملخص EN

Developments in next-generation wireless transmission technology and efficient frequency-use research are based on understanding the characteristics of the exact radio channel.

With regard to developments in next-generation mobile communication systems, performance verification of the development system is essential, for which it is necessary to estimate the exact wireless-space channel.

This paper presents results of the analysis of radio propagation characteristics based on location variation in outdoor environments for small-cell 5th generation (5G) mobile systems.

Changes due to variation in location were measured using a channel sounder in a microcell environment with a 0.5 km radius in Korea.

In order to analyze the propagation characteristics, the best distribution model reflecting the characteristics of the locations was derived.

A comparison between actual measurements and three-dimensional ray-tracing simulation results confirmed the validity of the measurement result.
