GL's voice and data testing solution goes mobile

August 14, 2014. GL Communications Inc. has announced the release of its enhanced Voice Quality Testing software with Wideband Bluetooth support using the next-generation Dual Universal Telephony Adapter (UTA).

Robert Bichefsky, senior manager for product development at the company, said, “Latest technologies such as VoLTE and Advanced LTE are expanding rapidly with deployment throughout all markets and all carriers. The VoLTE supports HD voice over AMR-WB networks and requires sophisticated testing for both voice and data quality. Testing must include older generation narrowband networks along with wideband networks when VoLTE to VoLTE calls are established and maintained. Along with voice and data testing, the next-generation networks also require delay and call retention testing. GL’s mobile test solution provides this capability with the flexibility of connecting to and between any network, any service, and any interface.”

He said that typical networks supported by GL's VQuad-Dual UTA hardware/software solution include wireless (VoLTE, LTE, 4G, and 3G) via Bluetooth or wired headset, broadband Internet (LTE, 4G, and 3G), VoIP SIP, PSTN, and TDM. Automated testing using GL’s VQuad includes the following attributes: Scripting with variable parameters, portability for mobile drive testing, remote accessibility from CLI or WebViewer, centralized data retrieval along with mapping to Google Maps, and analysis of voice and data.

“The VQuad software is used for automated call control as well as to automatically send and record voice files from most any type of network (wireless, VoIP, TDM, and analog),” he said. “It supports up to eight telephony devices simultaneously. A minimum of two telephony nodes are required for transferring files, either within same VQuad node or between multiple geographically separated VQuad nodes. The VQuad along with the next-generation Dual UTA, support for Wideband Bluetooth (as well as Narrowband Bluetooth) allows testing mobile devices supporting VoLTE networks (AMR Wideband).”

He added, “GL’s Mobile Device Controller (MDC) provides a liaison to all supported Apple/Android-based mobile devices for conducting data NetTests. The data tests can be remotely configured and automated from within any VQuad node irrespective of the mobile device proximity to the VQuad node. Specifically for smart phones, the VQuad can fully automate the data tests to any GL app-equipped phone irrespective of whether the device is on a voice call or not. The testing is fully automated with results sent to the central database (WebViewer).”
