Abstract
A method, apparatus, and computer program is presented for scanning in a wireless network. A wireless device receives a downlink frame from two access points, the downlink frames indicating their respective transmission powers. The wireless device then determines the closest access point and a transmission power sufficient to reach that access point. Then, the wireless device carries out transmission of a probe request with the determined transmission power.
