Title (EN) WIRELESS COMMUNICATION DEVICE AND COMMUNICATION CONTROL METHOD
(FR) DISPOSITIF DE COMMUNICATION SANS FIL ET PROCÉDÉ DE CONTRÔLE DE COMMUNICATION
(JA) 無線通信装置及び通信制御方法
Abstract:
(EN) A wireless communication device (10) is provided with: an array antenna (20) composed of a plurality of antenna elements (21a-21d); and a communication circuit (50) that carries out wireless communication by performing switching between a first mode and a second mode with use of the array antenna (20). Transmission power in the wireless communication during the first mode is greater than that during the second mode, and the communication speed during the first mode is higher than that during the second mode. During the second mode, the communication circuit (50) weights the amplitude of a signal for exciting at least two of the antennal elements (21a-21d), thereby carrying out the wireless communication with a directivity of the array antenna (20) wider than that during the first mode.
(FR) L'invention concerne un dispositif de communication sans fil (10) comprenant : une antenne réseau (20) composée d'une pluralité d'éléments d'antenne (21a-21d); et un circuit de communication (50) qui réalise une communication sans fil en effectuant une commutation entre un premier mode et un second mode à l'aide de l'antenne réseau (20). La puissance d'émission dans la communication sans fil pendant le premier mode est supérieure à celle pendant le second mode, et la vitesse de communication pendant le premier mode est supérieure à celle pendant le second mode. Pendant le second mode, le circuit de communication (50) pondère l'amplitude d'un signal pour exciter au moins deux des éléments antennaires (21a-21d), réalisant ainsi la communication sans fil avec une directivité de l'antenne réseau (20) plus large que celle pendant le premier mode.
(JA) 無線通信装置(10)は、複数のアンテナ素子(21a~21d)で構成されるアレイアンテナ(20)と、アレイアンテナ(20)を用いて第1モード及び第2モードを切り替えて無線通信をする通信回路(50)とを備える。第1モードは、第2モードよりも、無線通信における送信電力が大きく、かつ、通信速度が速い。通信回路(50)は、第2モードでは、複数のアンテナ素子(21a~21d)のうちの少なくとも2つのアンテナ素子を励振する信号に対して振幅の重み付けをすることで、第1モードよりもアレイアンテナ(20)の指向性を広げて無線通信をする。
