Hi Unless you are tired of remote control cars, a few reasonably new videos to look at during the IETF coffee breaks A test drive in an underground mine (Kankberg, Boliden, Sweden) with 5G NR access (3.5GHz). The peak throughput is more than 60Mbps in uplink, which means that both the front and rear camera video coders max out at ~28 and 12Mbps, giving a total bitrate of ~40Mbps, it is only at the remote end of the tunnel that the coverage is decreasing enough to reduce the throughput. In other words, congestion control-wise it is not so exciting, but at least the car got a decent workout https://www.youtube.com/watch?v=r7QxdTP3jB0 A winter wonderland-ish test drive with LTE access, on the 5G test site in Luleå, Sweden. The coverage is a bit limited and the congestion control limits the bitrate accordingly. https://www.youtube.com/watch?v=eU1crtEvMv4 Note!. The video is grabbed from screen with simplescreenrecorder and encoded, on top of that , an additional video coding is done in the editing, finally an additional encoding is done when the video is uploaded to YouTube. The actual video on screen is few notches better than what is seen on the videos. /Ingemar ================================ Ingemar Johansson M.Sc.
