Different forces present at that time used dozens of different radios. Most of the radios could only communicate with the other radios of same kind. Software Defined Radio (SDR) offered the promise of not only interoperating with all existing radios, but also allowing those radios to communicate with each other. Just as important, SDR has enabled future communication systems to be implemented on already deployed hardware. Software Defined Radio (SDR) is a radio communication system where components that have been typically implemented on hardware are instead implemented by means of software on a personal computer or embedded system.
