Abstract: In an example embodiment, a service that analyzes location information of a client as the client roams. For example, whenever a trigger event occurs, such as a change in the association state, a change in Internet Protocol (IP) address, etc., a determination is made whether the event was expected. If the event was not expected, the location of where the trigger event occurred can be determined enabling a network administrator to investigate roaming problems at a particular location.

Abstract: Methods and apparatuses of planning a wireless local area network are disclosed. Various embodiments receive data such as floor plan data, coverage data, and/or capacity data about a site for the WLAN. Based on such data, features of the WLAN access points can be determined. Examples are the quantity, placement, and/or configuration of the access points. Measured data, such as WLAN data, are received. The measured data are compared with expected data, such as expected WLAN data. Expected WLAN data can be generated from various sources, for example floor plan data and access point data (e.g., quantity, placement, and/or configuration). Based on such measured data, WLAN features can be changed, such as floor plan and/or access point data (e.g., quantity, placement, and/or configuration).

Abstract: A method and apparatus for communicating information. In particular, a method of communicating data between a plurality of applications, comprising the following steps. A first list is encoded. The first encoded list includes a first set of data objects. Each of the data objects includes data to be communicated. Next, the first encoded list is transmitted to a first of the plurality of applications and decoded for the first application. The first application accesses a first subset of data objects from the first encoded list. The first subset of data objects does not necessarily include all data objects in the first set of data objects. Next, the first application generates a second encoded list, where the second encoded list corresponds to the first encoded list. Then, the first application causes the second encoded list to be transmitted to a second application and decoded for the second application. The second application then accesses a second subset of data objects corresponding to the second encoded list, the second subset of data objects not necessarily including the same data objects in the first subset of data objects. The first application and the second of the plurality of applications exchange data type information for the second subset of data objects corresponding to the second encoded list.

Abstract: In an example embodiment, there is disclosed a technique that enables a wireless device to achieve coexistence with an interfering source. The wireless device determines when interference is present and not present during a service period and reports the duration of interference free interval. At the end of an interference period, the wireless device can send a trigger signal indicating the start of an interference free interval to request data be sent to the wireless station until the expiration of the duration of the interference free interval. In particular embodiments, the signal sent by the wireless device can include an offset, for example a timing synchronization function (TSF) value, to indicate the end of the interference-free interval, perhaps computed so as allow for some clock drift.

Abstract translation: 在示例性实施例中，公开了一种能够使无线设备实现与干扰源共存的技术。 无线设备确定在服务期间何时存在和不存在干扰，并报告无干扰间隔的持续时间。 在干扰周期结束时，无线设备可以发送指示无干扰间隔的开始的触发信号，以请求发送到无线站的数据，直到无干扰间隔的持续时间期满。 在特定实施例中，由无线设备发送的信号可以包括偏移，例如定时同步功能（TSF）值，以指示无干扰间隔的结束，可能被计算以允许一些时钟漂移。
