Intelligent radio is at its core an extension of software-defined radio technologies. Software-defined radio’s (SDR) are radio devices that can transmit and receive a range of signals, but have many of their radio functions implemented in software, rather than as circuit components. There are many functions as part of a radio system, some examples include which protocols to use, what frequencies to operate at, or the type of filter to apply to a signal. Many of these can be implemented in software.
Doing so allows a single device to be applied to many different purposes, based on the software used. As an example, the same hardware can be used to broadcast audio, as portable communications device, or as a wireless access point. Many SDR’s can be used together to achieve complex engineering objectives.
