Overview
GL’s Wireless Drive-Test solution supports hand-portable fully automated Voice and Data testing for both mobile phones and push-to-talk (PTT) radios. Mobile phone testing includes any mobile phone, any carrier, any network including legacy, next generation and future networks and phones. Radio testing supports any and all PTT radios with custom PTT headset cables between the radio and the GL hardware. Voice Quality metrics are provided using POLQA (per ITU-P.863) or PESQ (per ITU-P.862) with automatic DAQ conversion for radio testing.
The GL mobile drive test device, vMobile™, makes drive and walk testing simple and convenient by placing the vMobile™ in your pocket, in your car, on a plane, in a train, or anywhere where Voice and Data testing is needed including both outdoors and indoors. All Voice and Data results include full plotting using Google Maps and the GL Internal Tracking System. Using the vMobile™ internal Bluetooth interfaces one can connect to two mobile phones or connect to a single PTT radio using the analog headset interface. Automated testing is achieved using the vMobile™ scripting for placing and receiving calls as well as sending/recording audio during the established calls. Call metrics such as Call Failed and Call Dropped are supported. Voice metrics other than the POLQA and PESQ MOS include one-way and round-trip delay, signal and noise levels, audio dropout, frequency and power analysis. In addition the GL vMobile™ can work directly with the GL VQuad™ solution for very flexible end-to-end testing.
The vMobile™ internal GPS permits time synchronization between two geographically separated systems as well as location information during the drive and walk testing. If testing indoors the GL Indoor Tracking System (ITS) can plot all results automatically and directly on a user-provided floor map. All the test measurements and statistics are sent to the Central Database along with the GPS or ITS coordinates. Using WebViewer™ (web browser) the results can be plotted on Google Maps or on the ITS map for instant testing analysis.
Features
- Network independent Drive/Walk Testing solution (supports any Network and any Carrier)
- Voice and Data testing can be performed on-the-go using mobile devices (phone or tablet) and can run simultaneously when supported by the network
- Supports Narrowband, Wideband and Super Wideband audio
- 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
- vMobile™ and VQuad™ support a simple scripting methodology covering all voice and data quality KPIs
- Indoor Tracking System (ITS) in vMobile™/VQuad™ developed to test the VQT in remote and unreachable GPS signal locations
- Plot results using GPS coordinates or ITS when GPS is not available
- Full-featured remote capability that permits loading configurations, starting/stopping tests, and retrieving test results
- Obtain network signal strength levels from wireless phone
- The vMobile™ runs independent of Network connection and can be controlled directly from the onboard menu or via Bluetooth® connection. All network drops (both data and voice) are recorded to the vMobile™ logs and can be retrieved through the vMobile™ Console
- All results can be plotted on Google Maps and ITS Viewer, and also downloaded as a PDF via WebViewer™. With WebViewer™, users can filter reports, generate custom reports with line and bar graphs, and export them in Excel, CSV, or PDF formats
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.
vMobile™ connects to the mobile device using Bluetooth. A single vMobile™ can operate up to 2 wireless mobile phones (via Bluetooth®) or single PTT Mobile Radio. It includes a GPS receiver for providing location which can be used to plot the results on Google Maps using the WebViewer™.
Alternatively, VQuad™ can be used which 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®, PTT) 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™.
Data Drive Testing
Data testing require only the mobile device (phone or tablet). Using the GL NetTest 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's video conference 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™.
Drive and Walk Tests using two Mobile Phones with vMobile™
The graphics illustrate Drive and Walk tests using two mobile phones connected to the vMobile™. The vMobile™ runs a script to place and answer calls, then sends and records voice files in a loop during the call. These files are analyzed using the POLQA algorithm, along with measurements for Signal-to-Noise ratio, Speech Activity, and Audio Dropouts. The vMobile™ connects via WiFi through the mobile phone’s tethered interface, and is controlled using the Console app.
Drive and Walk Tests using two PTT Radios with two vMobile™
The graphics illustrate Drive and Walk tests where each vMobile™ is paired with a PTT radio. These vMobile–PTT pairs can operate in the same area or across distant locations. Each vMobile™ executes a simple script where the near-end device activates the PTT, sends a voice file, and the far-end records it. The process can then be reversed, with the far-end activating the PTT to send a voice file while the near-end records, all within an embedded loop. The recorded voice files are analyzed using the POLQA algorithm, along with measurements for Signal-to-Noise levels, Speech Activity, and Audio Dropouts. The vMobile™ connects via Wi-Fi through a tethered mobile phone interface, and device control is managed through the Console app.
Drive and Walk Test Setup and Results
The Drive test was from Gaithersburg MD to Ocean City, NJ USA and lasted approximately three and a half hours. The walk test was on the boardwalk of Ocean City, NJ during one summer morning and lasted approximately 40 minutes. During both tests the vMobile™ along with both mobile phones were placed in a small lightweight backpack (total weight 2lbs), easy for travel and easy to carry during the walk test. Similar testing can also be performed using two PTT radios with two vMobile™—one kept static and the other used during the drive or walk test. The onboard vMobile™ battery was sufficient for these drive and walk tests, however if extended tests are required an external Power bank (lightweight and inexpensive) can be connected to the vMobile™.

Indoor Tracking System (ITS)
GL’s Indoor Tracking System (ITS) functionality supports plotting voice quality results when GPS is not available (for instance indoors). The ITS allows viewing the results directly plotted on a user provided floorplan or map.
WebViewer™ simplifies indoor tracking where GPS is unavailable by plotting vMobile™ results directly on customer provided JPG floor plan or location diagrams associated with the testing environment. The GL ITS supports walk-tests in underground, remote, or inaccessible areas. This GL solution offers a user-friendly method for conducting efficient indoor or non-GPS accessible testing of radios or mobile phones.

Data Throughput Test
Using vMobile™ or VQuad™, data throughput can be tested on the mobile phones independent of the Voice Quality testing. Using an app installed on the mobile device (both Android and IOS supported), the vMobile™ can automate the GL NetTest™ testing solution with all results being sent to the Central Database and accessed using the WebViewer™. Below test results were run at same time as vMobile™ Voice Quality Drive test, essentially running one TCP speed test per VQT call.
