This talk will provide an introduction to software-defined radio and start by asking why we need SDR, before proceeding to taking take a look at the key components. The open hardware LimeSDR platform — which is being used to provide a GSM network at EMF Camp — will be covered in some detail as we explore its high level architecture.

Details of example applications will be provided and there will be short demonstrations of transmitting an LTE signal, and DVB-S transmit and receive.
