    • Apparatus (30) comprises a battery power supply, a radio-frequency transceiver, a multi-element antenna, and processor and memory. Software causes the apparatus (30): when in an idle mode, to broadcast positioning service advertisements and to refrain from broadcasting positioning packets, when in a positioning mode to broadcast positioning packets from each of the elements of the antenna (32A-C) such as to allow a mobile device (10) to determine a bearing to the mobile device (10) from the apparatus (30), and to transition from the idle mode to the positioning mode in response to receiving either a) a wake-up command or b) a positioning packet, from another apparatus including a multi-element antenna. The apparatus (30) may comprise a Bluetooth Low Energy transceiver; and software that causes the apparatus (30): to transmit advertisements for positioning services on a first channel; and to broadcast positioning packets on a second channel such as to allow a mobile device (10) to determine a bearing to the mobile device (10) from the apparatus (30), wherein the first and second channel are on different frequencies.

    • 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.
    • 一种用于在设备中提供定位功能而不必实现专用硬件的系统。 期望接收方向性信息的装置可以从另一装置(例如接入点或AP)接收消息。 AP可以以各种模式操作,例如,可以向其他设备提供方向性信息作为一般广播(例如,无线局域网或WLAN,信标信号)的一部分,或响应于请求方向信息的消息 从其他设备接收。 在从AP接收到消息之后,设备可以确定消息是否包括方向信息。 如果消息被确定为包括方向信息,则可以利用来自接收到的消息的定向信息来确定设备位置。 否则,设备然后可以向AP发送请求方向性信息的消息,这可以促使AP提供方向信息。
