SCA4 — An evolved framework

It has been over 10 years since the first iteration of Software Communication Architecture (SCA) and more than 5 years since the release of the previous version of the specification, SCA 2.2.2. While there have been numerous technological advancements and lessons learned in the field of software defined radio (SDR) since the release of SCA 2.2.2, the framework remained relatively static and was extended to include a small subset of the new features. The latest specification release, commonly known as SCA4, significantly optimizes the framework and improves a programmer´s ability to develop software defined radios efficiently. The new standard builds on a decade of expertise and makes the SCA even more relevant in today´s market of resource constrained systems with the ever increasing need for secure mobile communications. With the breadth of potential SCA based target platforms and applications, SCA4 broadens its applicability beyond U.S. military software defined radios.
