QualNet is a program for Windows that enables you to create, study, and improve communication networks. It can simulate various types, including wired, wireless, underwater, satellite, etc. There is support for thousands of nodes which exchange different kinds of traffic.

Build communication installation

The software uses a digital twin to display the whole network, encompassing various protocol layers, radios, antennas, and devices. You can work with advanced algorithms for Parallel Discrete Event Simulation. Thus, it is possible to boost the rate at which events are processed.

The graphical interface employs the drag and drop method for building network scenarios. You have the option to use preset models of devices, link types, and applications. There are several utilities to replicate network and app traffic. To design radio equipment installations, you may try a tool like Atoll.

Network visualization

It is necessary to highlight the support for a considerable number of models. The library includes items for wireless technologies, cellular networks, military waveforms, satellite and underwater communications. You may also choose devices such as routers, switches, and access points.

The program provides an intuitive platform to visualize and analyze network scenarios in real time. The heatmap feature can be used to improve layouts by considering the signal coverage of wireless transmitters. To access the available functions, you need to purchase a license.
