Techniques for collecting telemetry data, indicating usage of a computing-based solution hosted in a computing resource network, to ascertain a stage of progression through an experience lifecycle for the computing-based solution, and to generate data for populating lifecycle templates with content for progressing from the stage to which the user account has progressed to the next stage of the experience lifecycle, to include on a user interface for display on a computing device associated with a user account. A software agent executing on a node in the computing resource network may collect the telemetry data to provide to a Software-Defined Networking (SDN) controller disposed in the same network. The SDN controller may transmit the telemetry data to a service provider network, where the data is utilized to determine lifecycle data for generating a user portal to present on the computing device associated with the user account.

Analyzing telemetry data to track progress through an experience lifecycle and provide intelligent lifecycle-based information for computing solutions

Determining the location of a radio tag or client station of a wireless network, and the location of coverage holes by receiving from a plurality of wireless stations of the wireless network path loss information of the path loss of one or more location frames received at the respective wireless stations. The location frames transmitted by the radio tag or client station having a pre-defined frame structure. The radio tags and client stations use a common infrastructure for transmitting a location frame configured for radiolocation by path loss measurement. The common infrastructure includes a pre-defined protocol common for both radio tags and client stations for transmitting information for reception by the plurality of stations of the wireless network for radiolocation. The pre-defined protocol includes using the location frame having the pre-defined frame structure.

A convergent network with voice over Internet protocol (VOIP) and voice over wireless local area networks (VoWLAN) telephones provides users a way for notifying a network administrator of a quality problem in real time together with an indication of the nature of the quality problem. Upon receipt of the notification, the system takes a snap shot of the current network parameters that are associated with the quality problem and provides network statistics for subsequent analysis and troubleshooting. Other callers participating in a call are also notified of the source of the quality problem. In addition, when streaming video or audio users detect a network quality problem, the problem is marked and tagged to indicate the time and the type of quality problem as it is occurring.

Systems and methods for estimating channel response in the presence of interference. Interference and/or noise present on received training symbols is estimated. Based on the measured noise and/or interference, a weighting among training symbols is developed. Channel response is then estimated based on a weighted least squares procedure.
