Software Defined Radio (SDR) is a set of tools that allow you to build your own radio communications system.
It’s basically an open source, software-defined radio platform that allows you to create your own customized wireless devices.
SDR security is a new way of thinking about security. It’s not just about the hardware, but also the software that runs on top of it.
This means that instead of having to worry about your security camera system being breached by hackers, you can actually build a secure system from scratch.
