Overview
GL's WebViewer™ provides the method to display and access, in real time, the entire VQuad™/VQT network including all individual VQuad™ probes as well as the central location. Current status of the entire test is displayed along with customized user statistics and results of the active tests. The WebViewer™ uses a simple web browser with facilities to query the results either manually or automatically as well as output the results/statistics. These results include VQuad™ Call Event, User Defined Events, Bluetooth® events, Data Test (NetTest from PC and NetTest from Mobile Device), VQT, VBA, Delay and Echo Measurement results and Fax TxRx Events which can be saved to either text or Excel format. WebViewer™ includes support for user-defined statistics with both tabular and graphical outputs.
The WebViewer™ browser can also provide real-time status of the entire VQuad™/VQT network as well as remote accessibility of any node associated with the network. Transfer configuration files between the VQuad™ nodes and your local system for enhancements. Automatically send the updated configuration back to the VQuad™ system (or all VQuad™ systems). Rerun the test using the enhanced VQuad™ configuration, all from the WebViewer™ browser running on either Windows® based or Mac based systems (including iPhone and iPad devices).
GL’s VQuad™ provides automatic call control over several networks and supports transmit/capture of voice files in real-time from the various nodes. The degraded (recorded) voice files are automatically transferred to the Central Location where GL's VQT analyzes and generates the results using POLQA (ITU-T P.863), PESQ (ITU-T P.862) test methods. Additional analytical metrics are also provided as a result of the VQT algorithm including jitter, clipping, and level measurements.
GL's new VQuad™ Probe HD is an all-in-one self-contained VQuad™ with Dual UTA HD test instrument. This comprehensive hardware device incorporates all the features of the current VQuad™ with Dual UTA HD unit such as portability and remote accessibility along with the necessary PC hardware with Win7 OS. The VQuad™ probe HD can be controlled via Ethernet Remote Desktop (with support for mouse/keyboard) and is of same length as the current Dual UTA HD hardware, but about twice as high and 50% wider.
The vMobile™ - Portable VQT Test Solution is a handheld device which can support full audio testing for mobile phones and mobile radios, as well as providing data testing for mobile phones. The vMobile™ can be hand-carried for walk and drive testing (includes GPS) as well as left in labs and can work directly with GL’s VQuad™ solution for very flexible end-to-end testing. All functionality and configuration of the vMobile™ is accessed using the remote web-based Console or Console App which is installed on any Android or iOS device.
GL's Voice Analysis Tool (VAT™) application is used to analyze the audio content within any PCM audio files and generates a variety of audio metrics. VAT™ has a user-friendly interface to perform manual and automated analysis of multiple tests using a single PCM audio file received from the VQuad™, vMobile™, or any other applications.
Enhancements with the latest WebViewer™ includes customization of report generation with result statistics, tabular data, bar graphs, and line graphs. And the Report Scheduler gives the user the ability to specify when to schedule a report along with the schedule period and user-specified filters.

Components of GL's WebViewer™ Solution

Components of WebViewer™ Solution
GL's WebViewer™ solution is a four tier architecture. The first layer consists of GL's VQuad™ which establishes the proper calls or direct connections between the near and far end using a variety of physical interfaces. The File Monitor transfers the degraded (recorded) voice files from the individual VQuad™ nodes to one of several VQT/VBA/EMU systems which are located on the second layer. Each VQT/VBA/EMU applications automatically analyze the degraded voice file and transmit the analytical results to a single central database located at the Data Layer. This third layer provides a means for storing the captured results. The last layer is the Data Access Layer (Application Server) where the data presentation logic is contained. Each of these components is briefly explained below.
Data Layer
An Oracle or MS Access database (user specified) is used to store the analytical measurement results along with all pertinent data associated with the VQuad™/VQT/VBA/EMU/Data/Video Test systems (Call progress events, error events, timestamps, Call ID, location information, Echo Measurements, Data Test Results, Video Test Results, Fax Events, VQT PESQ and POLQA Events). This provides a very flexible and expandable architecture for data storage and data access. The database is accessed in real-time over the web using the WebViewer™.
The DataImport application is co-hosted with the database server running on the Data Layer. It collects the data posted by the probes and then updates the database using the collected data.
Data Layer of the WebViewer™ Solution
Application Server
The WebViewer™ provides an application server for accessing the VQuad™ Call progress events, user-defined error events, delay measurement results, Data Test results, Video Test results, Echo Measurement results, Fax Events and VQT PESQ/ VQT POLQA/VBA E-Model LQ/LQO/WB MOS measurements along with the additional analytical measurements including Call ID information. The results are queried over the internet using any browser-capable device such as desktops, table PCs MAC systems (Mac, iPhone, iPad) or PDAs. The application server is capable of serving the data in real-time or providing historic data based on customer selected filters.
