Large-scale FDTD analysis to obtain precise propagation characteristics of in-flight wireless access service

Electromagnetic field distributions created by a 2 GHz band wireless transmitter inside an aircraft cabin are analyzed and propagation characteristics are discussed from the analysis results. We use FDTD technique and a large-scale parallel computing technique to precisely estimate the field distributions inside cabin of a Boeing 777-200 aircraft model. In order to validate FDTD analysis results, the calculated electric field distribution is compared to actual field measurement in the aircraft cabin. Additionally, the absorption effect due to passengers can be considered.
