摘要： PROBLEM TO BE SOLVED: To efficiently attempt tradeoffs of quality of call, power saving and call cost. SOLUTION: Available wait modes are different, respectively, in response to the attachment or detachment of an interface for an external WAN, or voice direct call correspondence/non-correspondence. When the interface for the external WAN is not attached, only a VoIP dedicated mode can be utilized. When a built-in radio LAN interface as well as the interface for the external WAN, corresponding to a voice call by a public radio network are mounted, all the waiting modes can be utilized. Furthermore, when an interface 108b for an external WAN that does not cope with the voice call by the public radio network is mounted, only the VoIP-dedicated mode can be utilized.

摘要： PROBLEM TO BE SOLVED: To improve the communication between an RFID reader/writer 200 and an RFID tag 700 by devising the antenna 220 of the RFID reader/writer 200. SOLUTION: A radio tag reader/writer includes a second casing 240 accommodating the antenna 200 for communicating with the RFID tag 700, and a first casing 210 accommodating an RFID reader/writer 230 for writing information in the RFID tag 700 or reading information from the RFID tag 700. The angle formed by the antenna 220 and the RFID reader/writer 230 is the angle at which the electric wave sending/receiving surface of the antenna 220 and the sticking surface of the RFID tag 700 are opposite each other, at least during communication with the RFID tag 700.

摘要： PROBLEM TO BE SOLVED: To make a wireless IP telephone apparatus lower in power consumption, concerning a communication device and a system which can be connected to a wireless network and an IP network. SOLUTION: As a rule, a main CPU 130 shifts into a high-power consumption state, only when it is carrying out transmission processing of transmitting keep-alive signals to a SIP server, and otherwise keeps staying in a low-power consumption state. A controller 140, as a rule, shifts into a high power consumption state, only when it makes a reply to beacon signals sent from an access point, and otherwise keeps staying in a low-power consumption state.

摘要翻译：要解决的问题：为了使无线IP电话设备的功耗降低，涉及可以连接到无线网络和IP网络的通信设备和系统。解决方案：通常，只有当主CPU 130执行向SIP服务器发送保持活动信号的传输处理时，主CPU 130才转移到高功耗状态，否则保持在低功耗状态消费状态只有当控制器140对从接入点发送的信标信号进行回复，并且否则保持在低功耗状态时，控制器140通常转移到高功耗状态。版权所有（C）2007，JPO＆INPIT
