Simu5G: the 5G network simulator in real time and open source is born

Simu5G was born from the union of the Information Engineering department of the University of Pisa and the US multinational company Intel. It is the first simulator of a 5G network in real time and open source , freely downloadable and usable. Simu5G is the improvement of the popular SimuLTE 4G network simulator predecessor, incorporates access to 5G New Radio and allows simultaneous connection of numerous devices.

Simu5G simulates the 5G network in real time

The common project between Intel and UniPi arises from the need to respond to new market demands. In fact, there is an increasing need for extremely fast communications, to be able to make multiple devices interact in real-time and to be able to connect phones and computers. Advanced industrial sectors will need to connect numerous robots at the same time as they work, relying on applications based on the Internet of Things. Hence the idea of ​​the Computer Engineering department of the Pisa university and of Intel which aims to make companies and universities understand how the new generation connection works and the benefits it brings .

In Europe the state of distribution and propagation of the 5G network is still underdeveloped. Data dating back to November 2020 tells us that users of the aforementioned network are 779 for every 100 thousand inhabitants. Giovanni Stea, together with Giovanni Nardini and Antonio Virdis of the computer engineering department, are the creators of Simu5G and want to spread and make known this new technology.

Simu5G, the real-time simulator of 5G networks

Simu5G is based on the OMNeT ++ framework from which it borrows the concept of modularity. It is written in C ++, it is completely customizable thanks to a simple connectable interface, but above all it is open source and at no cost.

"In turn, we have decided to make it public, free and available to everyone, both companies and research institutions, precisely because we understand its potential in terms of support for innovation and digitization processes. necessary for our country "

Giovanni Stea

The Simu5G simulator can be integrated with other modules of the INET framework and offers support for optimization tools. Simu5G allows the simulation of 5G communications not only in F requency Division Duplexing (FDD) mode , operating on different frequencies, but also in Time Division Duplexing (TDD) , in cases where the transmission speed asymmetry between the uplink and the downlink is variable.

Simu5G looks to Europe

Born from an all-Italian idea, the Simu5G simulator does not stop there, it goes beyond borders and aims to conquer Europe. It will be used in numerous European projects including Hexa-X , which sees the construction of the 6G network, and in FED-XAI (Federated and eXplainable Artificial Intelligence) . The partnership with Intel has allowed to enrich the OpenNESS with Simu5G. OpenNess is edge computing software and thanks to the recent integration developers can test applications that need low latency and high bandwidth.

Simu5G and 5G: the advantages

The 5G term on which the Simu5G project is based includes all new and fifth generation technologies and standards. 5G can go up to 10 Gigabits per second and a more positive outlook sees a transmission speed that can go up to 10 times faster than that of 4G. Not only will there be improvements in terms of performance and frequency but also significant energy savings. All this will translate for all of us into new possible services that we can have at our disposal. Artificial intelligence, digital payments and digitization all shift from the need to make communication lines more powerful. Hence, 5G becomes fundamental for the country's economy. It is also good to dispel the myth that it harms our health . There are no data available confirming possible damage to humans.
