Voice, Video, and Data Quality Test Solutions

Overview

Communications is dramatically changing right now, as “mobility” and “IP” technologies such as LTE, Advanced LTE, WiMax, 3G, and Broadband Internet, lead this transformation. As these technologies are rolled out, basic voice/video/data quality will ultimately determine the fate of carriers and end equipment manufacturers. Simple and effective methods of testing voice, video, and data are sorely needed - GL’s Voice, Video, and Data Quality Test Solution provides this flexibility of connecting to and between any network, any service, and any interface.

VQuad™ - Dual UTA HD, or the all-in-one VQuad™ Probe HD forms the central point of control for performing automated tests for voice, data, and video to and from Wireless devices (WiFi, Bluetooth®, 3G, 4G, LTE), Broadband Internet (3G, 4G), VoIP devices, PSTN, and TDM circuits assessing performance, quality and reliability of practically any network. Various associated applications (Voice Quality, Video Quality, Data tests, Echo and Delay tests, Fax tests, VBA) works with VQuad™ to provide "end-to-end assessment" with additional test and measuring capabilities. All the applications work in conjunction with the VQuad™ for automatically and remotely analysing the captured data and sending the test results to the central database. You can query results remotely or control the tests using web-based WebViewer™.

Enhanced VQuad™ with Dual UTA HD supports two methods of automated testing of mobile devices, Bluetooth and Wired Headset using GL’s new cable, Smartphone with Automated Call Control (ACC). Through the VQuad™ script (or manual operation), calls can be setup and send messages using iPhone SIRI or Android Google Voice available on mobile devices. VQuad™ includes Text-to-Speech technology for automatically creating the necessary voice prompts required to work with Siri or Google Voice.

Further, VQuad™ scripting provides for automation, mobility, remote accessibility, along with centralized analysis and data retrieval, which are just a few attributes of GL’s next generation Voice, Video, and Data Testing solution.

Associated applications with VQuad™ includes:

• Voice Quality Testing (VQT) software for analysis according to widely accepted ITU (International Telecommunications Union) voice comparison algorithms (POLQA, PESQ LQ/LQO/WB).
• Data Quality Testing (NetTest™) application for performing automated data testing on a wireless or wired network; tests include TCP, UDP, VoIP, Route, HTTP, FTP, DNS, SMS, Email, SIMInfo, Phone Info, and UEInfo
• Video Quality Testing (VAC™) application for performing fully automated Video Conference testing and get Audio and Video MOS QoS results along with several analytical metrics. Optionally, GLNetTest app on mobile devices can initiate, control, and perform the entire video conferencing testing with the support of a Video Controller/Server and Video Clients (Agents).
• Echo Measurement Utility (EMU) for echo and delay measurements, including RTD, OWD, ERL, EPD, and more
• Voice-band Analyzer (VBA) for monitoring voice band traffic (Speech Level, Activity Factor, RMS Factor, DC Level, Noise Level, Jitter, Echo Return Loss, Echo Delay, and Echo Dispersion)
• Fax Quality Testing for emulation and analysis of T.30 faxes (GLInsight™ or FaxScan™)
• Drive Testing solution for plotting all results and call control information along with co-ordinates using GPS receiver option in VQuad™, and Google Maps option within WebViewer™
• WebViewer™ for web based controlling and monitoring VQuad™ nodes over the entire network 

Thus, GL provides the complete solution for Voice, Video, and Data Testing and Analysis. Listed below are the GL’s hardware / software platforms used for voice quality testing solutions across various networks.
