EFFICIENT WLAN DISCOVERY AND ASSOCIATION
First Claim
1. A method for wireless communication in a mobile device, comprising:
- identifying a wireless local area network (WLAN) access point associated with a location of the mobile device;
transmitting a Request to Send (RTS) frame to the access point;
receiving a Clear to Send (CTS) frame from the access point; and
determining that the access point is within range of the mobile device based on the received CTS frame.

Abstract
Methods, systems, and devices are described for discovering and associating with WLAN using Request to Send (RTS) and Clear to Send (CTS) frames. A mobile device may identify a WLAN access point associated with a location of the mobile device. The mobile device may transmit a Request to Send (RTS) frame to the access point and receive a CTS frame from the access point. The mobile device may determine that the access point is within range of the mobile device based on the received CTS frame. Some embodiments may provide for transmitting an association request frame to the access point in response to the received CTS frame. The association request frame may be transmitted to the access point in a time period associated with the CTS frame.
