Voice / Video / Data

Drive & Walk Testing

(Wireless Voice, Video, Data Quality Testing)


GL’s Wireless Drive-Test solution includes all the necessary functionalities within portable equipment for a true mobile test. The mobile device under test can be in your pocket, in your car, in a train, or virtually anywhere while tests are automatically executed in an automated fashion. The automated tests include Voice Quality, Video Quality and Data Quality.  The WebViewer™, a web-based client application, accesses the centralized database for results.

The Wireless Drive-Test solution includes support for call control of variety of mobile device networks – from 2G to 5G, including the capability of sending/recording voice, testing video conferencing, and testing a variety of data over the mobile devices, while analyzing their performance.

The new vMobile™ - Ultra 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™ can be accessed using the remote web-based Console or Console App which can be installed on any Android or iOS device.

In addition to the vMobile™ the GL VQuad™ with Dual UTA can be used for drive testing of mobile phones and mobile radios (up to 12 devices per VQuad™ system). Adding the optional GPS will support mapping all results onto Google Maps using the GL WebViewer. Both VQuad™ and vMobile™ can be used together as part of the drive test solution.

The GPS option (included as part of the vMobile™) permits time synchronization between two geographically separated systems as well as location information for drive testing. With an added wireless network connection, all functionalities can be remotely controlled, and all results transmitted to remote locations can be accessed on-the-go. Load configurations and start/stop the tests, grab test results and stream files to the command center locations.

All the test measurements and statistics results are sent to central database along with GPS co-ordinates and Indoor Tracking System (ITS) information. Using WebViewer™, these results are plotted on Google Maps and on the ITS GUI and accessible worldwide through WebViewer™ at any time.

  • Network independent Drive Testing solution (on any network)
  • The Indoor Tracking System (ITS) in VQuad™ / vMobile™ developed to test the voice quality in remote and unreachable GPS signal locations
  • Using GL’s App, Data and Video testing can be performed on-the-go using mobile devices (phone or tablet)
  • Voice, Video and Data testing can be run simultaneously (if the network allows)
  • vMobile™ - Ultra-Portable Equipment for Voice & Data Testing.
  • Support NB, WB, and SWB testing
  • Connect directly to end devices - Smartphones, Softphone, Phone Handset, or ATAs
  • Bluetooth® compatible for both Call Control as well as Audio Send/Record
  • Any time a loss of connection (connection drop) detected is reported to the central system helping to trace defects in the network.
  • Full-featured remote capability that permits loading configurations, starting/stopping tests, and retrieving test results
  • Test measurements, statistical results along with GPS coordinates, and ITS information are sent to a central database. Results are then saved, plotted on Google Maps and ITS GUI, and accessible worldwide through WebViewer™ at any time
  • Obtain network signal strength levels from wireless phone

Voice Drive Testing

Voice Drive Testing

Drive Testing (for Voice) means testing the mobile device, either using the native phone app or a VoIP app on the phone a call can be established with another mobile device or a static (landline) device. 

VQuad™ with Dual UTA HD and vMobile™ connects to the mobile device using Bluetooth (via Wi-fi, 2G, 3G, 4G, LTE, 5G or PTT Mobile Radio). The VQuad™ with Dual UTA HD and vMobile™ includes an optional GPS receiver for providing location which can be used to plot the results on Google Maps using the WebViewer™.

Alternatively, the new vMobile™ - Ultra-Portable Equipment connects to the mobile device using two Bluetooth® (via Wi-fi, 2G, 3G, 4G, LTE, 5G) or a single PTT Mobile Radio simultaneously.

The results of the fully automated solution includes Voice Quality (using POLQA), call failures, call drops, delay measurements (RTD and OWD), level measurements, and RSSI (signal strength of the phone).

The voice quality testing supports NB, WB and SWB testing. The VQT MOS scores using POLQA algorithm as well as the Call Control information can also be plotted using Google maps.

Data Drive Testing

Data Drive Testing

Data testing require only the mobile device (phone or tablet). Using the GL app (supports Android and IOS) manual and automated data testing can be performed using VQuad™ and vMobile™. The mobile device can be in your pocket, in your car, in a train, or virtually anywhere while automated Data Testing is performed. The mobile device will run the specified data test irrespective of whether the phone is on an active voice call or not. Automated Data Testing (NetTest) includes TCP, UDP, VoIP, Route, HTTP, FTP, DNS Email, and SMS.

All results along with GPS coordinates of when the test starts/ends are plotted in Google Maps which can be accessed using WebViewer™. The results include RSSI (Signal Strength), Network, and Phone information.

While the phone is connected to the Central System, all Connection Drops (loss of connection) are reported to the central database and can be plotted within Google Maps. This helps to find problematic areas within the network.

Video Drive Testing

Video Drive Testing

Video testing requires only the mobile device (phone or tablet). Using the GL app (supports Android and Windows/Linux) manual and automated video testing can be performed.

Video Conference testing supports testing between any two devices (agents) including Android mobile devices, Windows and Linux PCs. Each test allows configuration of the test such as video rates and bandwidth. Using the GL app or the VQuad™ software, both manual and automated video conference testing can be performed between any two agents. The A/V QoS results are provided along with several analytic metrics. 

Tests can be fully automated with results along with GPS co-ordinates sent to the central system. The results are plotted on Google Maps using the WebViewer™.

Results and GPS Mapping

The results of the Drive Testing - VQT (POLQA), Video, Time/Delay measurements, Data Test, Network Information, Mobile device status and all relevant information, including GPS timestamp and co-ordinates are sent to a central database. These results can be accessed in WebViewer™ and using the GPS information associated with these results can be plotted on Google Maps.

As shown in the screenshots below, Google Maps option within WebViewer™ plots various Results, VQuad™ with Dual UTA HD and vMobile™ Nodes, and Mobile Devices based on the GPS co-ordinates available.  Results include VQT POLQA, Data Tests, Video Tests, Call Connect Events, Echo and Delay Measurements.  GPS position of Mobile Devices along with the Device PhoneID, Device Name and the location are plotted. VQuad™ and vMobile™ Node locations and the VQuad™ and vMobile™ Node status such as Down or UP are also plotted. These are differentiated using default color codes and call-outs. Plotting can be done real-time while drive testing and testing at fixed locations world-wide.
