The method for monitoring a wireless link of a wireless node of a CPE device during operation of the CPE device, comprises the steps of taking samples of one or several of the following parameters in a defined time interval: Received Signal Strength (RSSI), modulation rate (Physical Layer Rate) and/or the number of spatial streams used for the wireless link, and calculating an average for that parameters by including a filtering of said parameters.

Method for testing a wireless link of a Wi-Fi node, and circuit performing the method

A method () and system () for controlling wireless local area network (WLAN) user quality in a multi-access point environment is provided. In order to ensure good quality of service/user experience in a multi-access point Wi-Fi™ setup in which a user roams with a station (), the access points () continuously or at intervals assess the wireless environment's quality and report to a control entity (). The control entity () determines, from the assessment data, alternative target access points () that could be used in case the link quality of a current connection between an access point () and the station () falls below a predefined value. The control entity () then instructs the access point () to actively disconnect the station () and selects a new target access point () to accept the stations () connection request.

WLAN user quality of experience control in a multi-access point environment

The present disclosure is directed towards a device and a method for evaluating a wireless link () of a wireless node of a customer premises equipment (CPE) device () during operation of the CPE device. The device and method includes determining an actual data-rate () of the wireless link, determining an available data rate () of the wireless link, and calculating a head-room () based on a required data rate () and the available data rate ().

Method for evaluating a wireless link, respective device, computer program and storage medium

A method for analyzing a wireless link () of a wireless node of a customer premises equipment (CPE) device () during operation of the CPE device comprises: performing an active test, during which a data transmission is forced through the wireless link, to obtain a first set of parameters, and performing before or after the active test a passive test, which is a monitoring mode during which a data transmission of the CPE device is monitored, to obtain a second set of parameters. In particular, based on the first set of parameters, it is determined whether and to which extent the wireless link is in an uncertainty zone, and based on the second set of parameters, the decision is made to assign an observed decrease in a measured data rate to physics effects or to interference effects.

The present disclosure is directed toward a device and a method for evaluating a wireless link established between an access point and a user equipment. The device and method include determining a level of Quality of Experience of an application intended to be run on the user equipment using a mapping between a parameter representative of the QoE of the application under different wireless transmission conditions and sets of parameters representative of said different transmission conditions of the wireless link.

Method for predicting a level of QoE of an application intended to be run on a wireless user equipment

A method () and system () for controlling wireless local area network (WLAN) user quality in a multi-access point environment is provided. In order to ensure good quality of service/user experience in a multi-access point Wi-Fi™ setup in which a user roams with a station (), the access points () continuously or at intervals assess the wireless environment's quality and report to a control entity (). The control entity () determines, from the assessment data, alternative target access points () that could be used in case the link quality of a current connection between an access point () and the station () falls below a pre-defined value. The control entity () then instructs the access point () to actively disconnect the station () and selects a new target access point () to accept the stations () connection request.

When a failure is detected of a communication link between a wireless access point and a service provider providing services to devices in proximity of said wireless access point, a probe request message is broadcasted on one or more wireless communication channels. The broadcasted probe request message includes a particular payload enabling the message to be identified as being a distress message reporting a failure of the communication link. Another wireless access point within wireless communication reach receiving a distress message may transfer a communication link failure report to the service provider in place of the wireless access point of which the communication link fails.

Method of communication failure reporting and corresponding apparatus

A method and a system for monitoring a wireless link of a wireless node of a CPE device during operation of the CPE device are provided, For example, the method comprises taking samples of one or several of the following parameters in a defined time interval: Received Signal Strength (RSSI), modulation rate (Physical Layer Rate) and/or the number of spatial streams used for the wireless link, and calculating an average for the one or several of the parameters by including a filtering of the one or several of the parameters.
