The Software Communications Architecture (SCA) is an open architecture framework that promotes development of “Software Defined” systems by clearly identifying the boundaries for software applications and their interactions with the physical hardware. The SCA facilitates the portability, interoperability and configurability of the software and hardware components used in embedded systems.
The SCA was originally developed by the U.S. military’s Joint Tactical Radio Systems (JTRS) to standardize the way in which Software Defined Radios (SDR) for the U.S. armed forces were to be built. Since then, the SCA has evolved with the input of the international radio community led by the Wireless Innovation Forum (WInnF).
