Push-to-Talk (PTT) radios have evolved from analog radios to digital 2-way radios. Even more recently PTT over Cellular services offers end users a more affordable and efficient two-way radio solution. Rigorous testing is critical for all communications equipment serving public safety, military, aerospace, and several other industries. Test tools must provide reliable measurements of user experience for those who rely on critical voice communications radio networks.

"GL's vMobile ™ is a handheld ultra-portable device that brings true mobility to voice and data quality testing for wireless devices (any mobile phone or radio), changing the way automated drive and walk testing is performed. vMobile™ is simple to set up and conduct simultaneous voice and data quality tests to benchmark the performance of any type of telephony device," said Robert Bichefsky, Director of Engineering at GL Communications Inc.

He further added, "The vMobile™ can interface with mobile phones via wireless Bluetooth or mobile radios via wired headset for voice quality testing. When connected to a mobile radio, fully automated PTT operation is available within the vMobile™ automated scripting. In addition, the vMobile™ 4-wire analog interface replaces any analog headset for any device."

While GPS is incorporated within the vMobile™ in order to stamp all results with GPS coordinates during testing, the vMobile™ also includes GL's Indoor Tracking System (ITS) for plotting voice quality results when GPS is not available (for instance indoors). 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.
