Abstract
A wireless client station includes a signal strength module configured to estimate signal strengths of signals received from a plurality of access points, wherein each of the signals includes a transmit power level signal. A control module is configured to determine path losses for each of the plurality of access points in response to the signal strengths and the transmit power level signals. The control module is configured to associate with one of the plurality of access points having a lowest one of the path losses. The control module is configured to adjust a minimum transmit power level of the wireless client station in response to the lowest one of the path losses and a receiver sensitivity of the wireless client station.
Claims12
A wireless client station, comprising:
- a signal strength module configured to estimate signal strengths of signals received from a plurality of access points, wherein each of the signals includes a transmit power level signal;
- and
- a control module configured to
- determine path losses for each of the plurality of access points based on i) the signal strengths and ii) the transmit power level signals,
- associate, in response to each of the signal strengths being greater than a predetermined signal strength threshold, with one of the plurality of access points having a lowest one of the path losses, and
- adjust a minimum transmit power level of the wireless client station based on i) the lowest one of the path losses and ii) a receiver sensitivity of the wireless client station.
A method of operating a wireless client station, the method comprising:
- estimating signal strengths of signals received from a plurality of access points, wherein each of the signals includes a transmit power level signal;
- determining path losses for each the plurality of access points based on i) the signal strengths and ii) the transmit power level signals;
- associating, in response to each of the signal strengths being greater than a predetermined signal strength threshold, with one of the plurality of access points having a lowest one of the plurality of path losses;
- and
- adjusting a minimum transmit power level of the wireless client station based on i) the lowest one of the path losses and ii) a receiver sensitivity of the wireless client station.
A wireless client station, comprising:
- a transmitter having a minimum transmit power level;
- a receiver having a receiver sensitivity, wherein the receiver is configured to receive signals from a plurality of access points, and wherein each of the signals includes a transmit power level signal;
- and
- a control module configured to
- estimate signal strengths of the signals,
- determine path losses for each the plurality of access points based on i) the signal strengths and ii) the transmit power level signals,
- associate, in response to each of the signal strengths being greater than a predetermined signal strength threshold, with one of the plurality of access points having a lowest one of the path losses, and
- adjust the minimum transmit power level based on i) the lowest one of the path losses and ii) the receiver sensitivity of the receiver.
