Scientists from Wrocław have developed a “cosmic internet”

Scientists have developed radically faster satellite communications. Thanks to a unique solution – E-SSA technology, it is possible to radically increase throughput without the need to reserve additional radio bands. This is a breakthrough in the field of satellite communications for the Internet of Things, experts said.

“Thanks to the project developed by scientists from the Wrocław University of Science and Technology, OrbitsIQ Global and the European Space Agency, the transmission of data from millions of devices around the world will become faster and more reliable. This is a breakthrough in the field of satellite communications for the Internet of Things,” wrote the press release sent on Thursday by the Wrocław university.

An international team, the key part of which are scientists from the Faculty of Electronics, Photonics and Microsystems of the Wrocław University of Science and Technology, is implementing its original solution, the E-SSA (Enhanced Spread Spectrum Aloha) technology, which allows for a radical increase in bandwidth without the need to reserve additional radio bands.

Until now, devices using satellite communications often had to “wait in a queue” to transmit data. New technology changes these rules – scientists report.

“It works like a multi-lane highway. It allows hundreds of devices to transmit data simultaneously on the same radio channel, without interfering with each other's transmission reception,” explained Dr. Hab. engineer Paweł Kabacik from the Wrocław University of Science and Technology.

During tests conducted on a satellite model, the system confirmed its high effectiveness: it supported 500 devices communicating at the same time. In just one second, the new technology correctly received up to 30,000 calls. data packets.

This is a significant improvement compared to the systems currently in use. The demand for data transmission via satellites is huge and systematically growing. This applies to many areas of our lives: from transport and logistics to agriculture and energy. The new solution will improve the operation of millions of sensors.

As explained by prof. Paweł Kabacik, scientists have taken a new approach to the issue of how devices using satellite Internet can share the available radio band.

“Using the latest integrated circuits and processors as well as the latest achievements in signal processing, we have presented a system that is much more capacious and ensures proper handling of the demand for exchanging a large number of short information,” Kabacik added.

The development of this solution is the result of combining the knowledge of scientists from the Wrocław University of Science and Technology with the experience of engineers from the European Space Agency and the skills of specialists from OrbitsIQ Global, which also operates in Poland.

“Cooperation with the Wrocław university is a key step for us in building secure communications around the world. This technology is not an ordinary improvement, but a major revolution on the market of widely available satellite communication services,” said Joe Euteneuer, president of OrbitsIQ Global. (PAP)
