Description
図1の(A)は通常の伝送状態を示す図である。一方、図1の(B)は障害物によって無線送信機(TxRF)から無線受信機(RxRF)への無線通信経路が妨害され、壁の反射パスを用いたため、データ伝送量が低下した場合の動作を示す図である。尚、以下の説明では、無線送信機及び無線受信機を単に送信機及び受信機と呼ぶ。
次に、図面を参照しながら本発明に係る第2の実施形態を、図7、図8を用いて詳細に説明する。尚、図7に示す構成要素において、図1に示す第1の実施形態と同じ構成要素には同じ番号を用いている。
また、本発明は、以下の処理を実行することによっても実現される。即ち、上述した実施形態の機能を実現するソフトウェア(プログラム)を、ネットワーク又は各種記憶媒体を介してシステム或いは装置に供給し、そのシステム或いは装置のコンピュータ(またはCPUやMPU等)がプログラムを読み出して実行する処理である。
Claims (6)
