A first bandwidth required by a first communication apparatus (A) at data transmission and a second bandwidth required by a second communication apparatus (B) at data transmission are presumed. Next, the first bandwidth presumed as mentioned is compared to a first bandwidth used which the first communication apparatus (A) currently uses and at the same time, the second bandwidth presumed as mentioned is compared to a second bandwidth used which the second communication apparatus (B) currently uses. The first bandwidth and the second bandwidth are then adjusted, and a third bandwidth which the first communication apparatus (A) uses at data transmission and a fourth bandwidth which the second communication apparatus (B) uses are determined.

摘要： To reduce time to point a directional wireless portable terminal (WPT) to an access point (AP) when data is downloaded from the AP to the WPT, a user points the WPT to the AP, performs a first operation and transmits a request of authentication and download to the AP. The AP requests a server to perform the authentication and the download. The server transmits information on a current situation to the AP. The AP calculates time required until the download can be started based on content capacity and the like and transmits information on the calculated time to the WPT. The WPT displays countdown until the download can be started. During that time, the server performs the authentication and, if successful, delivers content to the AP. When the download can begin, the user performs a second operation and transmits a request of re-authentication and download to the AP.
摘要翻译：为了在数据从AP下载到WPT时减少定向无线便携式终端（WPT）到接入点（AP）的时间，用户将WPT指向AP，执行第一操作并发送认证请求并下载到AP。 AP请求服务器执行认证和下载。服务器将当前情况的信息发送给AP。 AP计算基于内容容量等开始下载的时间，并将计算出的时间的信息发送给WPT。 WPT显示倒计时，直到下载开始。在此期间，服务器执行认证，如果成功，则向AP提供内容。当下载开始时，用户执行第二操作，并向AP发送重新认证和下载的请求。
