DIRECTION-ENHANCED NAVIGATION
A system for providing positioning functionality in an apparatus without having to implement dedicated hardware. An apparatus that desires to receive directional information may receive a message from another apparatus (e.g., access point or AP). The AP may operate in various modes that, for example, may provide directional information to other apparatuses as part of a general broadcast (e.g., a wireless local area network, or WLAN, beacon signal) or in response to messages requesting directional information that are received from other apparatuses. After receiving the message from the AP, the apparatus may determine if the message comprises directional information. If the message is determined to comprise directional information, directional information from the received message may be utilized to determine apparatus location. Otherwise, the apparatus may then send a message requesting directional information to the AP, which may prompt the AP to provide directional information.
