Description
図1は、本発明の第1の実施の形態における無線通信装置の構成を示すブロック図である。無線通信装置1は、高周波処理部2、変調部3、復調部4、制御部5、送信データ作成部6、受信データ解析部7およびアンテナ8を備える。
図7は、本発明の第2の実施の形態における無線通信装置の送信パケットの構成を示す説明図である。
図8は、本発明の第3の実施の形態における無線通信装置の送信パケットの構成を示す説明図である。本実施の形態における無線通信装置の構成は、第1の実施の形態と同様であるが、スロットの時間長の取り方が異なる。
図9は、本発明の第4の実施の形態における無線通信装置の送信パケットの構成を示す説明図である。本実施の形態の無線通信装置の構成は、第1の実施の形態と同様である。
図11は、本発明の第5の実施の形態における無線通信装置の送信パケットの構成を示す説明図である。本実施の形態は、第4の実施の形態と比較して、無線通信装置1の応答待ち受け時間の時間長さT3について、T3≧T0/2としたものである。この様にT3を設定することにより、時間T3内に必ず電子レンジの発振が停止するので、応答パケットを確実に受信することができる。
