Using millimeter waves to send information in the future

The more connected the society becomes, the more crowded the radio spectrum in mobile networks. To increase bandwidth in the next generation of networks – beyond 5G– Wallenberg Academy Fellow Marina Petrova will investigate and develop methods that also make it possible to send information using the millimeter-wave bandwidth in a robust and reliable way. 

In just a few decades, wireless communication has revolutionized our lives. Using mobile broadband, we can watch films, listen to music, chat with friends, and search for information via the Internet. However, as these services expand, more bandwidth is necessary and the bandwidth of the current network is insufficient. 

So that the next generation of networks – beyond 5G – can carry even more data traffic, Associate Professor Marina Petrova at KTH Royal Institute of Technology will investigate opportunities for sending data using frequencies in the millimeter-wave bandwidth (mmW). The advantage of mmW is that the bandwidth is greater, hence information can be sent at much higher speeds than today.

However, these waves are disrupted by physical barriers, thus the sender and recipient needed to be visible to each other. Therefore, Marina Petrova will develop technology that exploits these limitations by utilizing ideas from radar technology and machine learning so that the senders and receivers can model the world around them (including moving objects), thus creating a smart network that can extract and exploit knowledge of this world to optimize communications between senders and the desired receivers.
