Stand-alone LTE EPC Emulator


The software-based LTE EPC emulator mimics LTE EPC stand-alone to test the RAN.

What It Can Do For You

Flexible, portable, cost-effective solution to turn up eNBs and test UEs

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 
  • Emulators available per subsystem (MME Emulator, PCRF Emulator, etc.) 
  • True stateful simulation 
  • Handover support on X2 and S1 
  • 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 
  • Core network 5G ready


  • Release 14 compliant
  • Category M1 UE support
  • TM6 and TM9 support
  • FDD only (FDD and HD-FDD UEs are supported)
  • Support of multiple CE levels (only CE-Mode A is supported)
  • Support of message repetition for MPDCCH, PDSCH and PUSCH in full duplex (only MPDCCH, PDSCH and PUSCH supported)
  • Support of localized MPDCCH transmission
  • EPDCCH support for Category M1
  • No frequency hopping
  • Bandwidth must be >= 5 MHz for cells that also need to support Category 0 and above UEs


  • Release 14 compliant
  • Single-tone and multi-tone category NB1 and NB2 UE support
  • 15 kHz and 3.75 kHz subcarrier spacing are supported
  • All operation modes (in-band, guard band and standalone) are supported
  • Multiple NB-IoT and LTE cells can be used at the same time in the same eNodeB
  • Support of multiple coverage levels
  • Support of all NPDCCH, NPDSCH, NPUSCH and NPRACH configurations
  • Support of control plane CIoT optimization
  • Support of multi-DRB mode

  • IP Address eNodeB 
  • Primary DNS Address 
  • Secondary DNS Adress 
  • MAC Address Public Gateway 
  • GTP Tunnel IP Address and Port 
  • GTP Tunnel eNodeB IP Address
  • Integrity Algorithm 
  • IP Address to assign UEs on LAN

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. It can be integrated into virtually any CI system via the HTTP API, including Jenkins, CircleCI, Gitlab and others


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 1Q 2020) 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
