3. SCA 4.0 Approach 3
The SCA 4.0 specification has been
developed following the Model Driven
Architecture (MDA) approach
The specification has been developed as a
Platform Independent Model (PIM)
Appendices provide Platform Specific
Model (PSM) extensions for specific
technologies, e.g. CORBA

16. Appendix E – Platform Specification Model 16
E Transports and Technologies
E.1 – Common Object Request Broker
Architecture (CORBA)
Two profiles planned.
Full – Provides features for general platforms
and applications
Lightweight – Provides minimal features for
highly constrained resources
E.2 – C++
E.3 – OMG Interface Definition Language

17. Appendix F – Units of Functionality 17
Appendix F identifies specific sets and
subsets of functionality across multiple
areas.
The selection or omission of a given set of
functionality has impacts on which
interfaces are or should be supported.

27. Summary 27
SCA 4.0 provides a significant opportunity for
optimizing SCA implementations optimized for
specific deployment environments.
This flexibility presents significant test, validation
and certification challenges.
Reference implementations will diverge based
on selected units of functionality across radio
systems.
Several initiatives and R&D efforts to provide
initial proof of concept demonstrations of the
viability of SCA 4.0
