摘要： A system for indicating the relative direction of a target object or location as determined from the current position of a wireless communication device. The system employs Direction of Arrival determination using an antenna array for indicating the direction of a target device and includes facilities to activate a location-indicating transmission in a target device, the ability to request that a location-indicating transmission be activated in a remote target device, relevant information reception from a target device and the display of all potential target devices within effective transmission range of the wireless communication device.

摘要： 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.
