5G is on the news: 5G routers, mobiles, telephony networks support… it is here already.
Any communications middleware can use 5G as a data link, and ROS 2 is going to work “out of the box” in these networks, but Ericsson has presented some ideas to enable ROS 2 to use the advanced features of 5G.
5G routers allow you to ensure different QoS for different channels also called Unique Networks Flows. You can do things such as reserve bandwidth, ensure guaranteed low latency, etc. All you need to do is to create a unique network flow in your application, and set-up the QoS in your 5G network.
In order to simplify this process, Ericsson and eProsima are enabling native ROS 2 support for creating unique network flows, and we will present some results already in the next middleware WG. Ericsson is working on the RMW support while we are creating the feature at Fast DDS level.
You can count on this feature very soon, and in the meanwhile, we will publish a more complete blog post with some technical details.
