VIAVI has been a highly collaborative partner with our two companies’ engineering teams working together to prove a new technology against very tight customer timescales.
TM500 – масштабируемая система тестирования для валидации производительности сети в опыте конечного пользователя в мультисотовых структурах и различных технологиях радиодоступа. Благодаря интегрированным службам передачи данных система способна измерять полную производительность от RF до ядра сети, включая взаимодействие с другими пользователями, моделируемую среду и мобильность радиодоступа, точно воспроизводя профили поведения реальных пользователей, такие как просмотр веб-страниц, электронной почты, загрузки файлов, просмотра потокового видео и передачи голоса по LTE (VoLTE). Подробнее о развертывании 5G.

Test Scenarios
A set of core test case scenarios allows the user to assess the performance of network features within a loaded network environment. The TM500 supports multiple real stateful data applications enabling true end-to-end data generation and analysis per emulated mobile device. Test cases can easily be configured for thousands of application data flows, and allocated to different mobile device groups with different traffic profiles.
User Operation
The design, scheduling and analysis of complex test cases is made easy via an intuitive graphical user interface. Test scenarios managing thousands of mobiles having individual mobility and data applications profiles can quickly be created and executed within a drag-and-drop environment. Upon test completion, measurements and KPIs can be viewed or exported to third party tools for post processing and advanced analysis.
Real Data Services
The TM500 Family supports multiple real stateful data applications enabling true end-to-end data generation and analysis per emulated mobile device. Test cases can easily be configured for thousands of application data flows and allocated to different mobile device groups with different traffic profiles.
Performance KPIs and Statistics
To enable complete performance analysis, the system produces a comprehensive set of measurement logs, KPIs and protocol metrics during and after each test case run.
