摘要： A wireless access point in a wireless network that may be adapted to transmit location data indicating its location to other devices within range, including other wireless access points and client devices. In some embodiments of the invention, the location data may be embedded in a control message or announcement transmission transmitted by the wireless access point, or other message conventionally used to broadcast network characteristics necessary for a client device to establish a connection to the wireless access point. In terms of the Open Systems Interconnect (OSI) layered model of a network, layer 2 control messages, including beacons, probe responses, or other suitable transmissions may be used for control messages or announcement transmissions. The other wireless access points and client devices may receive the location data broadcast by the wireless access point without establishing a connection to the client device. Devices receiving the location data may use the received location data to determine their own locations, and may provide the determined locations to consumers of location data.

摘要： Discovery of services between devices is provided prior to establishing a connection between devices, including wireless-enabled devices or devices that are communicatively coupled to wireless access points or other wireless communication devices. Discovering services prior to establishing a connection may facilitate finding a desired service. The services that may be discovered may be, for example, print services, camera services, PDA services or any other suitable services. Services may be discovered using 802.11, Bluetooth, UWB or any other suitable wireless technology. A graphical user interface is provided that enables a user to select a desired service.

摘要翻译：无线网络中的无线接入点，其可以适于将指示其位置的位置数据发送到范围内的其他设备，包括其他无线接入点和客户端设备。在本发明的一些实施例中，位置数据可以被嵌入在由无线接入点发送的控制消息或通告传输中，或者常规地用于广播客户端设备建立与无线接入点的连接所需的网络特性的其他消息。在网络的开放系统互连（OSI）分层模型方面，可以将第2层控制消息（包括信标，探测响应或其他合适的传输）用于控制消息或通知传输。其他无线接入点和客户端设备可以接收由无线接入点广播的位置数据，而不建立到客户端设备的连接。接收位置数据的设备可以使用接收到的位置数据来确定它们自己的位置，并且可以向位置数据的消费者提供确定的位置。
