Fully Autonomous Testing of Mobile Subscriber Experience

To continuously improve and maintain superior network performance and optimal subscriber experience, mobile operators must consistently monitor Quality of Service (QoS) and Quality of Experience (QoE) KPIs across their network. This is very challenging for mobile operators striving to minimize operational expenses, since ongoing network testing throughout a coverage area has traditionally required highly-skilled engineers in the field.

With TEMS Voyager, mobile operators, engineering services, enterprises, government, and regulators can now, through small or large-scale deployment of fully autonomous mobile network testing probes, actively measure and analyze network performance and subscriber experience across entire coverage areas, while significantly reducing the need for RF engineers in the field.

TEMS Voyager

Expand Your Mobile Network Testing

Remotely Configured. Fully Autonomous.

TEMS Voyager is a powerful data collection software developed for fully autonomous mobile network testing of subscriber experience using a TEMS Remote probe.

TEMS Voyager software runs on an autonomous TEMS Remote probe with an integrated consumer smartphone, making it the ideal solution for mobile operators and engineering service providers who want to minimize operational costs associated with regular wide-scale testing of Quality of Service (QoS) and Quality of Experience (QoE) across the network.

Simply mount one or more TEMS Remote probes running the TEMS Voyager software in a vehicle or a fleet of vehicles (e.g. buses, trains, delivery trucks, etc.), and begin actively measuring and monitoring mobile subscriber experience throughout all network coverage areas. Everything else is done remotely by engineers in the back office using TEMS Director to configure, manage, and monitor all the autonomous mobile network testing campaigns. And using the TEMS Director Analytics dashboard, RF engineers can analyze KPI performance real-time. TEMS Discovery can also be combined with TEMS Voyager for post-processing and geospatial analysis of network performance.
