1. A method performed under control of a mobile device, the method comprising:
- receiving at least one probe response from one or more Wi-Fi access points;
counting a number of the one or more Wi-Fi access points that transmit the at least one probe response;
comparing the counted number of the one or more Wi-Fi access points to a selected value; and
responsive to the comparison of the counted number of the one or more Wi-Fi access points to the selected value;
increasing a transmission signal power level, associated with a probe request, in response to the counted number of the one or more Wi-Fi access points being less than the selected value;
decreasing the transmission signal power level, associated with the probe request, in response to the counted number of the one or more Wi-Fi access points being greater than the selected value; and
transmitting information to a location estimation server, in response to the counted number of the one or more Wi-Fi access points being equal to the selected value, wherein the information corresponds to the transmission signal power level associated with the probe request.

Abstract
A method performed under control of a mobile device may include receiving at least one probe response from at least one access point; determining whether a number of the at least one Wi-Fi access point satisfies a predetermined condition; adjusting a signal transmission power of a probe request, when the determining indicates that the number of the at least one Wi-Fi access point does not satisfy the predetermined condition; and transmitting the probe request with the adjusted signal transmission power.

9. A mobile device, comprising:
-
a receiver configured to receive at least one probe response from one or more Wi-Fi access points; a processor coupled to the receiver, wherein the processor is configured to; count a number of the one or more Wi-Fi access points that transmit the at least one probe response; compare the counted number of the one or more Wi-Fi access points to a selected value; increase a transmission signal power level, associated with a probe request, in response to the counted number of the one or more Wi-Fi access points being less than the selected value; and decrease the transmission signal power level, associated with the probe request, in response to the counted number of the one or more Wi-Fi access points being greater than the selected value; and a transmitter coupled to the processor and configured to; transmit information to a location estimation server, in response to the counted number of the one or more Wi-Fi access points being equal to the selected value, wherein the information corresponds to the transmission signal power level associated with the probe request. - View Dependent Claims (10, 11, 12, 13, 14)
