QualNet - Network Simulation Software

The QualNet® network simulation software (QualNet) is a planning, testing, and training tool that “mimics” the behavior of a real communications network. Network simulation is a cost-effective method for developing, deploying and managing network-centric systems throughout their entire lifecycle. Users can evaluate the basic behavior of a network, and test combinations of network features that are likely to work. Our network simulation tool provides a comprehensive environment for designing protocols, creating and animating network scenarios, and analyzing their performance.

QualNet: Network Simulation Software

QualNet has been established as a network simulation tool for over 20 years, becoming a standard choice within commercial, military and government organizations.

It allows users to simulate the behavior of complex, large scale communications networks. With this, you can reduce the time, cost and risk of deploying new networks or technologies, whether it is across a city or a battlefield.

Simulate New Hardware and Set Ups

A network simulation tool allows testing for a range of requirements and situations, such as:

  • Designing new architecture or operating modes, using pre-configured or user-designed models
  • Running “what-if” scenarios by varying the model, network, and traffic parameters
  • Test new radios in operationally accurate contexts
  • Simulating response and impact of planned network upgrades
  • Modeling mobile wireless equipment in ground-based, seaborne and airborne environments

This video shows the network simulator for a set of mission scenarios. Each can be tested to clarify any performance effects on the mission. This allows for any necessary modifications along with increased confidence in the deployment.

EXata+Cyber, Our Cyber Security Solution

To help clients prepare for and protect against cyber attacks, we introduced our EXata+Cyber Software.

Network scenarios can be simulated for various forms of cyber attacks. The user can see how the network will respond, identifying any vulnerabilities or to test new hardware changes. Here are some of the cyber attack simulations offered:

  • Eavesdropping
  • Radio jamming
  • Virus attacks
  • Distributed denial of service (DDoS)
  • Signal Intelligence (SIGINT) attack

For wired, wireless, mobile ad-hoc and tactical networks.

These tests are becoming increasingly vital across a range of industries, such as telecommunications, oil & gas and building management.

Extending capabilities with our model libraries

Model Libraries for QualNet and EXata greatly extend the base capabilities of each tool.

With a few clicks, you can add a range of situations and details to your model. Whether it’s the terrain, antennae weighting or signal-to-noise interference, we are either likely to have an existing model or can work with you to create one.

Our model libraries currently include:

  • Wireless Library, for 802.11ac, 802.11ax, 802.11a/b/g, 802.11n, 802.11p, 802.11s and 802.11e, Bluetooth, Thread
  • Cellular Library for modelling GSM cellular networks
  • Military Radios Library for Link-11, Link-16, surrogate JTRS (WNW) radios, and other standards and models
  • Propagation Libraries, , terrain and urban pathloss effects
  • UMTS Library for third Generation (3G) mobile broad-band networks and LTE Library for 4G cellular networks
  • And many more


A full suite of network simulation tools

QualNet Architect – This is made up of two parts. The first is design, where you set up the terrain, network and functional parameters, along with any other details. The second is visualisation, where you can see the data packet flow, dynamic graphs and real-time statistics.

QualNet Analyzer – Get the full data for hundreds of metrics, in reports, graphs or exports. With in-depth data, you can compare simulations and what-if scenarios with multi-experiment reports.

QualNet Packet Tracer – Learn how data moves through a protocol stack and around your network. You can do so through animated visualisations over your model or XML exports, helping you identify any interruptions.

Ongoing training and support

We are able to offer ongoing training and support to ensure you get the most out of the network simulation suite. This can be through in-person training sessions, online, or by contacting our online helpdesk.

SCALABLE also has a Professional Services Organization (PSO) whose members are experts in modelling and simulation. They are available for everything from:

  • developing custom model libraries
  • architecting and creating complete network models
  • managing complete simulation projects

To ensure you get results from your projects.
