Polystar Solver

Flexible, scalable testing

Talk to us about this

Solver is a high-performance load generation, stress and feature testing solution for legacy and NGN fixed and mobile networks, including LTE.

Solver offers powerful, multi-protocol functionality and helps ensure smooth deployment and troubleshooting for networks. Proven in multiple deployments, it has won awards for its ease of use and advanced functionality.

By simulating traffic from the Radio Access Network (RAN) it helps CSPs and network equipment manufacturers to simplify performance analysis, assert full control over their networks, manage upgrade projects and confirm compatibility between equipment from different vendors.

Key Features


Solver can simulate multiple radio technologies and generate high traffic volumes for flexible load testing. This dramatically simplifies qualitative performance analysis for equipment manufacturers, CSPs and enterprises.

A wide range of traffic patterns can be created to run simultaneously or in sequence in order to simulate real world call traffic patterns. The flexibility allows anything from basic call scenarios to full load testing to be performed.



Solver is a simple, user-friendly tool that considerably reduces troubleshooting effort and time. The combination of LTE and legacy network technology into a single, convenient package means that operators can considerably simplify their test equipment needs, as well as dramatically reduce costs.

One platform provides the versatility required for a multitude of tasks, increasing return on investment. For example, fully integrated SRVCC test capabilities ensure a smooth migration to VoLTE.
