Although in the last year there was a lot of commercial activity for Software Defined Radio, the current military status is not clear while the JTRS program is being reorganized.
Adaptivity at all levels—from functions to services—is a highly desired attribute in SDR and cognitive radios. Although users will be exposed to adaptivity at service and application levels, adaptivity at component and function levels is also necessary for implementation.
There is a fear that software radios will inherit the problems of PCs, including their unreliability and their vulnerability to malicious code. But, digital signature technology coupled with high-assurance COTS operating systems can enforce a wide range of SDR security requirements.
Open SDR standards provide significant benefits to all stakeholders, including: platform and system developers, application developers, system integrators, regulators, service providers and end users. The SDR Forum has chartered the SCA Working Group to facilitate broad international acceptance of SCA as an open standard for wireless communications.
Until their onboard processing densities enable near-complete autonomy, communications technologies remain a critical issue for Unmanned Aerial Vehicle control systems.
