Overview

GL's VQuad™ mTOP™ Solution is an all-in-one self-contained VQuad™ with Dual UTA HD test instrument designed for conveniently testing up to 12 independent telephony devices in your lab.

A single VQuad™ can support up-to 6 Dual UTA HD units [Two-stacked 1U mTOPs], thus supporting connection to 12 independent telephony devices. VQuad™ supports multiple tests to run simultaneously on devices connected to Dual UTA HD. Dual UTA HD (High Density) includes support for Bluetooth® Wideband, FXO Wideband and SIP Wideband (ex: AMR WB), with which you can easily interface with any Mobile Device, FXO, or SIP devices supporting HD Voice. It has the ability to generate Wireless as well as 2-Wire and 4-wire analog calls using same hardware.  You can perform simultaneous Voice, Video, Data, Fax, and Time Delay Measurements from a single VQuad™ mTOP™ test solution - greatly reducing the licensing costs per device.

VQuad™ mTOP™ can perform simultaneous In-lab Tests, Drive Tests, Walk-around tests. VQuad™ mTOP™ solution can also be deployed for drive-testing within a car. Using the daisy chain feature of GPS, a single GPS receiver plugged to one mTOP™ unit allows to pass GPS to each of the mTOP™ systems.

In Walk-Around System, a single mTOP™ with three Dual UTAs is used for easier portability and convenient testing. VQuad™ Probe HD device is recommended for Walk-around test type.

You can use ready-to-use scripts for simultaneously testing Voice, Video, and Data Quality and benchmark performance of up to 20 mobile devices in the network. The entire test process can be automated, and test results automatically sent to a central system in the lab via TCP/IP for remote monitoring and call control.

The image depicts a real-time in the lab setup where the VQuad™ mTOP™ solution is deployed to perform simultaneous Voice, Video, and Data Quality tests to benchmark performance of up to 12 telephony devices in the network. For this solution, we are using two mTOPs (mTOP™ 1 that includes an SBC connects to mTOP™ 2 via USB). So, essentially creating a system with one VQuad™ system and 6 Dual UTA HDs. All devices on all six Dual UTA HDs are supported including FXO, 4-wire Analog, PTT, and Bluetooth.

Separate 1U PCs are also mounted which include Central Database with WebViewer™, VQT POLQA, GL NetTest Mobile Device Controller (MDC), GL NetTest Target Server, and VAC Agents. All systems are connected to the central system for remote monitoring, remote operation, and storing results/events.

All results and events can be queried and filtered using the WebViewer™ (web browser). Create Custom Reports, display results graphically, show results on Google Maps, and display status of all connected systems. Using the WebViewer™ you can also remote control the individual VQuad™ systems.
