Learn more about our supported technologies 

  • Supported network technologies and codecs

    Our solutions offer powerful, multi-protocol functionality and help ensure smooth deployment and troubleshooting.

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

    Supported network technologies 

    With our solutions you can simulate UE traffic towards 2G, 3G, 4G, and 5G mobile core networks.

  • Application technologies

    Our solutions are designed for comprehensive application server testing and support a large number of application protocols.

    • Application server protocols
    • Integration and Support Servers
    • Radius/Diameter, RTP/RTSP/RTMP Streaming, HTTP Streaming, and SIP/MSRP extensions (as additional packages)

    As well as in-built support for existing protocols, support for new or different interfaces can be added quickly and easily. Different protocol operations can be mixed together in test cases enabling realistic simulation of user behaviour.
