1. A method performed under control of a mobile device, the method comprising:
- receiving at least one probe response from at least one Wi-Fi access point;
counting a number of the Wi-Fi access points that transmit the at least one probe response;
determining whether the counted number of the Wi-Fi access points is within a predetermined range;
responsive to a determination that the counted number is not within the predetermined range;
adjusting a signal transmission power of a probe request, andtransmitting the probe request with the adjusted signal transmission power; and
responsive to a determination that the counted number is within the predetermined range, determining location information of the mobile device based at least, in part, on the probe request or the at least one probe response.

Abstract
A method performed under control of a mobile device may include receiving at least one probe response from at least one Wi-Fi 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.

10. A mobile device, comprising:
-
a receiving unit configured to receive at least one probe response from at least one Wi-Fi access point; a determining unit configured to; count a number of the Wi-Fi access points that transmit the at least one probe response, and determine whether the counted number of the Wi-Fi access points is within a predetermined range; a signal power adjusting unit configured to, responsive to a determination by the determining unit that the counted number of the Wi-Fi access points is not within the predetermined range, adjust a signal transmission power of a probe request; a transmitting unit configured to transmit the probe request with the adjusted signal transmission power; and a location calculating unit configured to, responsive to a determination by the determining unit that the counted number of the Wi-Fi access points is within the predetermined range, determine a location of the mobile device based at least, in part, on the probe request or the at least one probe response. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A non-transitory computer-readable storage medium having stored thereon computer-executable instructions that, in response to execution, cause a mobile device to perform operations, comprising:
-
receiving at least one probe response from at least one Wi-Fi access point; counting a number of the Wi-Fi access points that transmit the at least one probe response; determining whether the counted number of the one Wi-Fi access points is within a predetermined range; responsive to a determination that the counted number of the Wi-Fi access points is not within the predetermined range; adjusting a signal transmission power of a probe request; and transmitting the probe request with the adjusted signal transmission power; and responsive to a determination that the counted number of the Wi-Fi access points is within the predetermined range, determining location information of the mobile device based at least, in part, on the probe request or the at least one probe response.
