Software-Defined Radio (SDR) is predicted to become the dominant technology in radio communications, with many advantages over more traditional radio systems including:

  • Significantly wider operating ranges from low MHz to GHz.
  • High instantaneous bandwidth by combining RF streams within the software domain.
  • Increased operating freedom, the adaptive nature of SDR allows self-monitoring and dynamic reconfiguration to optimise performance in the field.
  • Reduced total cost of ownership; replacing multiple traditional radio sets with a single hardware platform, able to support multiple end-use applications.
  • The protocol agnostic RF front ends allows software to determine, decode and encode to any protocol required on the fly.
