Progress is deeply engrained in the structure that makes up the GNU Radio project. A lot of it has been made in 2020 – but unlike crop circles, we do know where it came from, and what we can do with it.

GNU Radio is the widest used software radio stack for research and development on PC-style hardware, having enabled hundreds of high-rate applications. I'll discuss where its limits are, where we need to stick to GNU Radio's recipe for SDR success, and where to disruptively address its architectural shortcomings

Today's GNU Radio hits hard limits when it comes to a few things that are absolutely crucial for modern communication stacks: It doesn't make any guarantees on latency, and its architecture doesn't allow for tight integration with hardware accelerators. And whilst most communications are packet-based, packeted data is a second-class citizen in the kingdom of sample streams that is GNU Radio.

In this talk, we'll discuss why that is the case, and what can be remedied within the current framework, and what not. We'll try to assess what usage paradigms are worth keeping for the future of GNU Radio, and what needs to change.

GNU Radio is one of the biggest and most widely adopted SDR framework in the free software world. In this talk, we will lay out how we intend to keep it going for the next year, and beyond.

GNU Radio is one of the biggest and most widely adopted SDR framework in the free software world. It's history is pretty interesting, and spans multiple decades at this point. However, we're far from being done! We will talk about how we intend to keep the samples flowing in 2019, and beyond.

There's no reason SDR needs to be limited to an elite group of users. There are so many tools out there that allow anyone with some technical background to quickly get familiar with the world of SDR. Depending on your background (Ham radio operator, software developer, wireless researcher, Michelin star chef) you may already know some parts of the big picture, but might be missing others. The last few years, many tools have been created to ease your entry into SDR, and we will give an overview of what they are and how you can quickly get started working with electromagnetic waves. No prior knowledge required!

Assuming you can operate a Linux computer, we will use the following tools to get you started with SDR and GNU Radio: - PyBOMBS - GNU Radio Companion - gr_modtool
