MMW remote antenna system of vector network analyzer for propagation measurement in stadium

摘要

Under the dense user conditions such as stadia, the millimeter wave propagation might be influenced by the reflection from surrounding spectators. In this paper, we analyze millimeter wave propagation, which becomes a problem in realizing millimeter wave communication at the stadium. In order to extend the distance between the transmitter and the receiver, a millimeter wave propagation measurement system using radio over fiber was developed. By using the system, Millimeter Wave (MMW) propagation irradiated from the ceiling of the stadium to the spectator seats was analyzed. If the cell is set small with the directional antenna, it is found that the influence of the reflection of the surrounding spectators is small, and a good prospect is obtained.
