The Valid8 5G Network Emulator provides an all-in-one, cost-effective and ultra-portable 5GC network for development, demonstration, testing and training purposes.

What It Can Do For You

The 5G Network Emulator solution is capable of simulating network nodes and and testing devices individually or in parallel. There are options available to include a real base station (available 2Q2019) if you need to use real UEs or IoT devices with traffic generation, or our simulated RAN if you don’t need the RF interface. Subsystems can be switched on or off depending on how much of the network you need simulated.

Example: A network equipment vendor or service provider would want to test how their network would function in a real deployment.

  • Will it properly handle Control plane and User plane traffic?
  • Will it conform to 3GPP standards?
  • How will it perform under load?

Why It’s Different

  • Scalable software-based architecture can run on a range of hardware from COTS and high-end customer provided hardware to Virtual Machines and the Cloud (e.g. Amazon AWS) for maximum versatility and performance
  • Web-based UI is easy to learn
  • HTTP API enable integration with automation test systems and other equipment
  • Stateful modeling provides accurate emulation of network elements


  • Emulates some or all of core network, exposing all internal interfaces
  • Can run alongside 4G and 3G core network emulators
  • Conformance tests available for each interface
  • Emulators available per subsystem 
  • OTA connection available (2Q2019) for UEs and IoT devices
  • True stateful simulation
  • Signaling request/response messages for call handling, mobility management, authentication, QoS
  • Report on media received, call connect time, call duration, jitter, packet loss
  • Generate valid and invalid/negative messages and call-scenarios (fully editable scenarios)
  • Supports sending invalid messages including malformed, dropped, and misordered packets
  • Check parameters in messages from SUT and flag errors
  • 3GPP-compliant interfaces


The Valid8 5G Network Emulator is compromised of multiple subsystems that are available individually or in parallel, and are scalable to fit your needs. The individual emulators are controllable through their call controllers, and the traffic can be captured through use of a remote capture tool such as Wireshark.

Automation API

User commands can be fully automated using REST API. This includes performing all test control functions as well as collecting results and metrics.


The application’s subsystems can be edited directly in the browser using TDL or by using the graphical tools. The Message Workshop allows for creating of test scenarios directly from the hex stream of a remote capture, while the Graphical Editor (on the feature roadmap for 2019) will allow for creating customized call scenarios by dragging and dropping the call flow to meet your test needs.

Use Cases

eNodeB Under Test

In the scenario where the eNodeB is to be tested, it can be tested by the Valid8 4G Network Emulator emulating the core network. Additionally, load and conformance tests are available for interfaces S1-MME and S1-U. In the case where the eNodeB needs to be tested on the RF side, it can be tested by the Valid8 4G UE Emulator.

Supported Scenarios:
  • ‍Power on / Start up
  • Attach
  • TAU
  • Attach
  • eRAB Setup
  • Detach
  • X2 handover
  • Emulates MME (for S1-MME) and SGW (for S1-U) along with all other needed core network elements, exposing all internal interfaces
  • Conformance tests available for S1-MME, S1-U, and X2
