GAITHERSBURG, Md. – GL Communications Inc. in Gaithersburg, Md., is introducing a voice quality test and measurement solution for public safety, military, and aerospace radios using the company's vMobile ultra-portable handheld device.
Push-to-talk (PTT) radios have evolved from analog radios to digital two-way radios. Even more recently PTT over cellular services offers end users an affordable two-way radio solution.
The vMobile handheld radio "brings true mobility to voice and data quality testing for wireless devices, changing the way automated drive and walk testing is performed," says director of engineering at GL Communications.
The vMobile radio is simple to set up and conduct simultaneous voice and data quality tests to benchmark the performance of any type of telephony device, Bichefsky says.
The mobile radio can interface with mobile phones via wireless Bluetooth or mobile radios via wired headset for voice quality testing. When connected to a mobile radio, automated PTT operation is available in the vMobile automated scripting. The vMobile 4-wire analog interface replaces any analog headset for any device.
GPS is incorporated in the vMobile in order to stamp all results with GPS coordinates during testing. The radio also includes GL’s Indoor Tracking System (ITS) for plotting voice-quality results when GPS is not available.
When GPS is available the results are plotted directly to Google MAPS, when GPS is not available the GL ITS plots all results on a user provided graphical floor plan or map.
The vMobile radio connects to any mobile radio as a wired analog headset or wireless Bluetooth headset; performs voice-quality analysis; offers measure one way delay, PTT audio connection delay time, and PTT grant tone delay time on radio networks; provides automated and hands-free testing; and supports voice quality testing using POLQA (ITU-P.863) and PESQ (ITU-P.862) algorithms.
