    • A system for geographic tagging of network access points comprises a plurality of access points that have been configured to provide location information as part of their beacon. Each access point provides a service set identifier (SSID) that includes an encoded value that represents the location of the access point. The use of an encoded location value in the SSID of the access point is particularly advantageous because it does not require any additional hardware be added to the access point or the portable computing device. Moreover, location can be determined by any portable device without establishing a connection to the access point. The portable computing devices are adapted to receive the beacon, extract the location information from the beacon and decode the beacon. The present invention also includes a variety of methods including: a method for geographic tagging of network access points, a method for encoding a location into a geographic code, a method for decoding a geographic code into a location, a method for encoding height into a geographic code, a method for decoding height from a geographic code and a method for determining the location using a plurality of geographic codes.
    • 用于网络接入点的地理标记的系统包括已被配置为提供位置信息作为其信标的一部分的多个接入点。 每个接入点提供包括表示接入点位置的编码值的服务集标识符(SSID)。 在接入点的SSID中使用编码的位置值是特别有利的,因为它不需要向接入点或便携式计算设备添加任何额外的硬件。 此外,位置可以由任何便携式设备确定,而不建立与接入点的连接。 便携式计算设备适于接收信标,从信标中提取位置信息并解码信标。 本发明还包括各种方法,包括:网络接入点的地理标记方法,将地理编码为地理码的方法,将地理码解码为位置的方法,将高度编码为 地理代码,用于从地理代码解码高度的方法和使用多个地理代码确定位置的方法。

    • The present invention provides systems and methods for self-labeling access points with their geographic location from received beacon frames. In particular, the present invention transmits beacon frames including temporary location information from mobile devices. The beacon frames are received by an access point, filtered by the access point and then used to determine a location. Once the location has been determined, the access point uses the determined location to self-label itself by converting the location information to a geographic code and inserting it as part of the SSID of the access point's beacon signal. The present invention also includes a number of methods using geographic codes including a method for generating and transmitting geographic codes for mobile devices, a method for determining a location of an access point, a method for self-labeling an access point, and a method for filtering beacon frames.
    • 本发明提供了用于从接收到的信标帧对其地理位置进行自标识接入点的系统和方法。 特别地,本发明从移动设备发送包括临时位置信息的信标帧。 信标帧由接入点接收,由接入点过滤,然后用于确定位置。 一旦确定了位置,接入点就使用确定的位置通过将位置信息转换为地理码并将其作为接入点的信标信号的SSID的一部分来进行自标识。 本发明还包括使用地理代码的多种方法,包括用于生成和发送用于移动设备的地理代码的方法,用于确定接入点的位置的方法,用于对接入点进行自标签的方法,以及用于 过滤信标帧。
