Last year at Mobile World Congress (MWC) we provided the multicasting protocol to a demo where we send low latency live video to 30 tablets (you can see last years demo at the end of this news post). This years setup is a bit different. The setting is a miniature stadium where there are two demos running in parallel.
Demo 1 - Network coded device to device optimization In this demo it is assumed that several thousand people are in the stadium and they are connected to a 5G cellular network. The screen of eight users are shown (the eight smartphones around the miniature stadium). The video performance show some degradation in case of severe channel conditions. To mitigate this there is the option to enable network coded device to device communication to support the 5G network. With re-coders at the devices, the video performance increases significantly and reduce the resource consumption at the cellular level.
Demo 2 - wurf.it to the spectators We used our multicasting system, wurf.it, to make it possible for the visitors at Nokia’s booth to download an app and connect to the black camera at the miniature stadium. This gave the visitors an opportunity to experience the stadium demo on their own devices.
