摘要： [Object] To prevent or reduce the degradation in transmission characteristics caused by fast fading (fluorescent lamp interference) to achieve optimized throughput.[Solution] A process for detecting fast fading (fluorescent lamp interference) is performed (ST2). Fast fading is detected by, for example, detecting a variable light source whose frequency is twice the frequency of an alternating current power supply. When fast fading is detected, a frame length update process is performed (ST3, ST4). In the case of “subject transmission” in which the subject apparatus is the transmitter of a data frame, the setting of the maximum number of aggregations in frame aggregation (A-MPDU, A-MSDU) is changed to “the recommended maximum number of aggregations”. “The recommended maximum number of aggregations” is set in advance so that the UDP throughput can be maximized under the conditions where fast fading has occurred. In the case of “subject reception” in which the subject apparatus is the receiver of a data frame, the subject apparatus sends a request message for limiting the maximum transmission length to the communication counterpart apparatus.

摘要： A portable terminal monitors a signal level of a short-range wireless signal from a wireless communication apparatus. If the signal level drops so low that a state of connection for short-range wireless communications cannot be maintained between the two apparatuses, use of predetermined functions of the portable terminal is limited. A short-range wireless communication facility of the portable terminal and the wireless communication apparatus move into a particular operation mode if communications do not occur therebetween at least for a predetermined time period. In monitoring the signal level of the wireless signal from the wireless communication apparatus in the particular operation mode, the portable terminal reduces a response speed at which to detect a signal level change. This causes the wireless communication apparatus to delay issuing a request for an increase in transmission power, thereby reducing unevenness of the working distance at which to alert a user to the unusual distance traveled between the two apparatuses or beyond which to limit the use of some functions of the portable terminal.
摘要翻译：便携式终端监视来自无线通信装置的短距离无线信号的信号电平。如果信号电平下降到两个设备之间不能维持短距离无线通信的连接状态，则限制了便携式终端的预定功能的使用。便携式终端和无线通信装置的短距离无线通信设备如果至少在预定时间段内不发生通信，则移动到特定的操作模式。在特定操作模式中，在从无线通信装置监测无线信号的信号电平时，便携式终端降低了检测信号电平变化的响应速度。这导致无线通信装置延迟发出增加发送功率的请求，从而减少工作距离的不均匀性，在该距离处警告用户在两个装置之间行进的异常距离或超过这些距离限制使用某些功能的便携式终端。
