vMobile™ for Satellite network testing
Voice Quality Testing of Radios over Satellite
Voice Quality Testing of Satellite Phones
Satellite communications networks handle diverse traffic from commercial internet to mission critical communications. Unfortunately, Satellite networks are prone to numerous network impairments, such as reduced bandwidth, long latency, packet loss and jitter. These impairments affect user experience, especially for voice traffic or other streaming services. Poor voice quality impacts government and military operations as well as private and home internet use.
GL’s test tools are designed specifically to test user experience and can be used to test any communications network. Key metrics include Voice Quality scores (Mean Opinion Score), measuring delay and detecting dropouts. GL’s test equipment interfaces with endpoint communications devices, such as satellite phones and radios. These solutions enable thorough monitoring and analysis of satellite networks.
GL’s tools allow users to send and receive voice and data traffic in real-time over satellite networks using vMobile™. This handheld device can interface to both mobile phones and radios via onboard Bluetooth® and wired connections. vMobile™ performs call control of the connected device, instructing the phone to place and answer calls, send and receive audio, and disconnect the calls. The vMobile™ records the audio captured over the satellite network and sends the file to a central database (through an out-of-band network) for voice quality analysis. The central database is called WebViewer™.
WebViewer™ includes a web-based dashboard allowing users to access results from anywhere in the world via a standard web browser. If access to an out-of-band network is not available, vMobile™ can store the files locally until the user can upload to the database at a later time. Additionally, vMobile™ offers real-time analysis of critical network performance metrics, ensuring reliable communication even in remote locations where terrestrial networks are unavailable. Whether deployed for field testing or used in lab simulations, vMobile™ provides valuable insights to troubleshoot satellite communication networks.
