Title (EN) PORTABLE WIRELESS COMMUNICATION APPARATUS AND COMMUNICATION CONTROL METHOD FOR SAME
(FR) APPAREIL DE COMMUNICATION SANS FIL PORTABLE ET SON PROCÉDÉ DE COMMANDE DE COMMUNICATION
(JA) 非設置型無線通信装置およびその通信制御方法
Abstract:
(EN) [Problem] To provide a portable wireless communication apparatus and a communication control method for the same which reduce radio emission toward a user and allow efficient communication. [Solution] The present invention has a first antenna (301) which has directivity to a specific direction when viewed from the apparatus main body, a second antenna (401) which emits radio waves to a direction to which at least the first antenna cannot emit radio waves, and control units (352 and 353) which select the first antenna or the second antenna such that radio emission toward the user is reduced.
(FR) L'invention a pour but de proposer un appareil de communication sans fil portable et son procédé de commande de communication qui réduisent une émission radio vers un utilisateur et permettent une communication efficace. A cet effet, la présente invention a une première antenne (301) qui a une directivité vers une direction spécifique lorsqu'elle est vue depuis le corps principal d'appareil, une seconde antenne (401) qui émet des ondes radio vers une direction vers laquelle au moins la première antenne ne peut pas émettre d'ondes radio, et des unités de commande (352 et 353) qui sélectionnent la première antenne ou la seconde antenne de telle sorte qu'une émission radio vers l'utilisateur est réduite.
(JA) 【課題】使用者へ向けての電波放射を低減させ、かつ効率的な通信を可能にする非設置型無線通信装置およびその通信制御方法を提供する。 【解決手段】装置本体から見て特定方向へ指向性を有する第1アンテナ(301)と、少なくとも第1アンテナが電波を放射できない方向への電波を放射する第2アンテナ(401)と、使用者へ向けての電波放射が低減するように第1アンテナあるいは第2アンテナを選択する制御部(352,353)と、を有する。
