Abstract: front page image
(EN)[PROBLEMS] To provide a wireless communication device, a wireless communication system, a program, and a wireless communication method. [MEANS FOR SOLVING PROBLEMS] The wireless communication device which wirelessly communicates with other wireless communication device has a control part, which makes a control for preparing for a data loss in wireless communication of transmission data, and a transmission part which wirelessly transmits the transmission data according to the control made by the control part. The one or the other wireless communication device estimates a distance between the wireless communication device and the other on the basis of the field intensity of a wireless signal judged to meet predetermined conditions as for noise components out of wireless signals received from the remaining one of the wireless communication devices. The control part makes a control of a content according to the estimated result of the distance.
(FR)L'objet de l'invention est de proposer un dispositif, un système et un procédé de communication sans fil et un programme. Le dispositif de communication sans fil de l'invention qui communique sans fil avec un autre dispositif de communication sans fil comporte une partie contrôle qui réalise un contrôle pour se préparer à une perte de données lors d'une transmission sans fil de données de transmission, et une partie transmission qui transmet sans fil les données de transmission en fonction du contrôle réalisé par la partie contrôle. L'un ou l'autre des dispositifs de communication sans fil estime la distance entre les dispositifs de communication sans fil sur la base de l'intensité du champ d'un signal transmis sans fil remplissant des conditions prédéterminées en ce qui concerne les composants de bruit hors des signaux transmis sans fil reçus à partir du dispositif de communication sans fil restant. La partie contrôle réalise un contrôle d'un contenu selon le résultat estimé de la distance.
(JA)【課題】無線通信装置、無線通信システム、プログラム、および無線通信方法を提供すること。 【解決手段】他の無線通信装置と無線通信を行う無線通信装置に、送信データの無線通信におけるデータ損失に備える制御を行う制御部と、前記制御部による前記制御に従い、前記送信データを無線で送信する送信部とを設け、前記無線通信装置または前記他の無線通信装置の一方は、前記無線通信装置または前記他の無線通信装置の他方から受信した無線信号のうちで、雑音成分に関する所定条件を満たすと判断される無線信号の電界強度に基づいて前記他方との距離を推定し、前記制御部は、前記距離の推定結果に応じた内容の制御を行なう。
