［奨励講演］ウェアラブルポディエリアネットワーク向け無線通信の伝搬特性に関する研究

摘要

近年、医療支援やヘルスケア向けの技術開発が盛んに行われ、情報通信分野においても人体の生体情報の収集と伝達に利用できる技術としてBody Area Network（BAN）の研究開発が行われている。本研究は人体の表面上で構成するWearable BAN（WBAN）を研究対象とし、これまで必ずしも明白ではなかった人体表面上の電波伝搬特性について、実際に人体を用いて測定を行い、その結果からチャネルモデル構築を行った。%We concentrate on wearable BAN (WBAN), which provides communication links among sensors deployed on body surface. We measured radio propagation on body surface and derived channel models to clarify radio propagation characteristic of body surface. In order to design a WBAN that manages biological information with high efficiency and high reliability, the propagation characteristics of WBAN must be thoroughly investigated. A large number of measured data were collected, from which channel models for WBAN were derived. The parameters to describe WBAN channel models were specified.
