Active remote 4G/5G monitoring

27 September 2023 Test & Measurement

Keysight has recently introduced the advanced 4G/5G network active remote monitoring solution, Nemo Active Probe. With the new solution, wireless service providers and national regulators can perform roaming and regression testing.

This solution combines detailed and comprehensive measurement capabilities with cost-effectiveness and proven automated functionality. Nemo Active Probe´s unattended deployment minimises the necessity for dedicated field personnel and reduces operational expenses. Automation enables efficient allocation of resources, allowing technically-adept personnel to focus on problem-solving and network development tasks instead of spending time in the field. As a result, time spent on network testing is reduced by 20%, while manual field-testing work is reduced by 80%.

Combining Nemo Active Probe with Keysight´s remote monitoring solution, Nemo Cloud, and Keysight´s analysis tool, Nemo Analyze, creates a complete end-to-end solution to remotely monitor live networks and visualise key performance indicators. With Nemo Cloud, a single user can monitor and control numerous fixed and mobile probes worldwide from a centralised location.

Nemo Active Probe supports all major technologies and the latest Android-based smartphones and test protocols. Service measurements for data and voice are also supported, including voice call and voice quality testing.

The probe unit’s design incorporates effective thermal control mechanisms such as a fan and optional active cooling elements. This ensures that 5G test devices remain fully functional, preventing overheating during prolonged tests.

Nemo Active Probe is an ideal solution for performing unattended large-scale measurements within key locations where smartphone usage is prominent and ensuring uninterrupted network service is critical. The probes can be discreetly deployed in hotspots and fixed locations, such as airports, offices, campuses, and shopping malls, and in moving vehicles, such as trains, taxis, delivery trucks, and ships.
