Drive Testing

Features

• Network independent Drive Testing solution (on any network, even those which have yet to be deployed)
• Data and Video testing can be performed on-the-go using mobile devices (phone or tablet) with GL App.
• Voice, Video and Data testing can be run simultaneously (if the network allows)
• vMobile™ - Ultra-Portable Equipment for Voice & Data Testing.
• Support for both NB and WB (VoLTE) testing
• GLNetTest VQT mobile application available for Android devices supporting manual and automated voice quality testing operations
• Device independent voice solution (any phone which supports Bluetooth). GL Data solution runs on any Android or IOS device (or PC), while the GL Video solution runs on any Android or PC
• 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.
• The Indoor Tracking System (ITS) in VQuad™ developed to test the VQT in remote and unreachable GPS signal locations
• The ITS information (location, timestamp) saved in the VQT database per VQuad™ Measurement
• Full-featured remote capability that permits loading configurations, starting/stopping tests, and retrieving test results
• Obtain network signal strength levels from wireless phone

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. 

GL's NetTest VQT app, supported on rooted Android devices, supports both manual and automated testing of Voice Quality within the network. The GL NetTest VQT app includes features to place and receive calls over the network along with Play and Record voice over the established call.

VQuad™ connects to the mobile device via the Dual UTA HD using Bluetooth. A single VQuad™, on a PC, along with Dual UTA HD can operate up to 4 wireless mobile phones (via Bluetooth®, Wi-fi, 3G, 4G, LTE, PTT Mobile Radio) simultaneously. The Dual UTA HD 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 VQT Test Solution connects to the mobile device using Bluetooth®. A single vMobile™ can operate up to 2 wireless mobile phones (via Bluetooth®, Wi-fi, 3G, 4G, LTE, 5G and 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 both NB and WB (VoLTE) 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 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. 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 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™/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™ Node locations and the VQuad™ 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.

Wireless Call Control

GL's VQuad™ software and vMobile™ application has the ability to automatically control the wireless phone (via data cable or Bluetooth®) for placing calls, answering calls, disconnecting calls, and obtaining relevant information such as network signal strength is available using the VQuad™ Call Control option.
