A method in a computing device includes: monitoring, via a communications interface of the computing device, wireless data elements including application data corresponding to a communications application, and non-application data; automatically generating labels based on the application data of the wireless data elements, the labels indicating performance impacts observable in the communications application; selecting a portion of the wireless data elements corresponding to the non-application data; extracting, from each wireless data element of the non-application data, a set of feature values; generating a plurality of samples from the non-application data, each sample including (i) a number of the sets of feature values based on a sample size, and (ii) one of the automatically generated labels; training a classifier based on the plurality of samples, the classifier configured to receive further non-application data and generate a predicted impact indicator selected from the labels; and deploying the classifier.

Application-independent detection of wireless environment impacts

A computing device includes: a wireless communication interface; and a processor configured to: establish a connection with a wireless network; while a network-layer status of the connection is active, monitor attributes of the connection at the wireless communication interface, the attributes including (i) a number of uplink packets transmitted since a most recent downlink packet was received, and (ii) a time period elapsed since the most recent downlink packet was received; determine that the attributes meet recovery criteria indicative of a network-layer interruption in the wireless network; in response to the determination, control the wireless communication interface to initiate a recovery action to resolve the network-layer interruption.

Detection and recovery mechanisms for network interruptions

Wireless local area network (WLAN) field coverage is analyzed in a venue. A mobile data capture device measures coverage data indicative of the WLAN field coverage from a plurality of locations in the venue, and also captures image data indicative of images of the locations in the venue. A controller correlates the measured coverage data and the captured image data at each location. An interface displays the captured image data correlated with the measured coverage data at each location. Impact score value data indicative of the WLAN field coverage may also be determined, correlated, and displayed for each location.

Arrangement for, and method of, analyzing wireless local area network (WLAN) field coverage in a venue

A client device and method for analysis of a predetermined set of parameters associated with a radio coupling to a WLAN is provided. The client device includes a memory and a radio coupled to at least one processor. The at least one processor executes in the memory a first client Wireless Local Area Network (WLAN) stack having a plurality of layers configured to couple the radio to a WLAN. The at least one processor also executes in the memory a second client WLAN stack emulating the plurality of layers of the first client WLAN stack. The at least one processor is configured to receive, at the second client WLAN stack, data from the plurality of layers of the first client WLAN stack and analyze a predetermined set of WLAN parameters of the client device based on the data received from the plurality of layers of the first client WLAN stack.

Client device and method for analysis of a predetermined set of parameters associated with radio coupling to a WLAN

A system for monitoring wireless communications in a client device includes a wireless communications interface, including: an analyzer; a monitoring controller coupled to the analyzer; an operational controller of the client device coupled to the wireless communications interface, the operational controller configured to: control the wireless communications interface to establish a wireless connection with an access point according to a set of connection parameters including a channel identifier; and transmit the set of connection parameters to the monitoring controller; the monitoring controller configured, responsive to receiving the connection parameters from the operational controller, to: monitor a channel corresponding to the channel identifier to obtain a plurality of frames transmitted over the channel; and provide the plurality of frames to the analyzer.

System, method and apparatus for monitoring wireless communications

An apparatus and method for establishing mobile connectivity conditions for mobile subscriber units in a wireless communication network includes scanning, by each mobile subscriber unit, for candidate access points and affiliated channels for roaming, whereupon the unit can roam from an originating access point to one of the candidate access points on an affiliated channel for roaming. A link record in the mobile subscriber unit is used for recording an entry including the originating access point, the candidate access point, the affiliated channel for roaming, and a handoff experience value. The link record can be used upon subsequent roaming of the unit to attempt a self-devised handoff without further scanning for access points and affiliated channels. Link records can be shared between mobile subscriber units to speed up map building of link records.
