    摘要： Operation of a mobile voice client utilizing a WLAN for access is enhanced by controlling the rate at which transmission power is changed by the access point with which the mobile voice client is associated. The access point calculates a target transmit power level based at least in-part on the distance to the nearest fixed position wireless device and the distance to the mobile voice client. The access point then determines whether the target transmit power level differs from a current transmit power level. If the target transmit power level is greater than the current transmit power level, the current transmit power level is increased at a first controlled, non-instantaneous rate such as 1 dB per second. If the target transmit power level is less than the current transmit power level, the current transmit power level is decreased at a second controlled, non-instantaneous rate such as 1 dB per second.

    摘要翻译： 利用WLAN进行接入的移动语音客户机的操作通过控制与移动语音客户端相关联的接入点发送功率变化的速率来增强。 接入点至少部分地基于距离最近的固定位置无线设备的距离和到移动语音客户端的距离来计算目标发射功率电平。 接入点然后确定目标发射功率电平是否与当前发射功率电平不同。 如果目标发射功率电平大于当前发射功率电平，则当前发射功率电平以第一受控非瞬时速率增加，例如每秒1dB。 如果目标发射功率电平小于当前发射功率电平，则当前发射功率电平以第二受控非瞬时速率（例如每秒1dB）降低。

    摘要： The performance and ease of management of wireless communications environments is improved by a mechanism that enables access points (APs) to perform automatic channel selection. A wireless network can therefore include multiple APs, each of which will automatically choose a channel such that channel usage is optimized. Furthermore, APs can perform automatic power adjustment so that multiple APs can operate on the same channel while minimizing interference with each other. Wireless stations are load balanced across APs so that user bandwidth is optimized. A movement detection scheme provides seamless roaming of stations between APs.
