Abstract
The Assured Communications in Challenging and Contested Environments (AC3E) Project comprised demonstrations of techniques for robust and reliable communications in remote and/or under-serviced regions such as the Arctic, and the development of concepts and techniques for flexible and adaptive spectrum access to provide robust networked communications in dynamic environments. Policy-based decision making combining situational awareness and user requirements was the foundation for demonstrations of the Northern Access Node and real-time spectrum access testbeds, which showed how robust channel access can be achieved with low overhead and operator burden. As modern waveforms are quite interference tolerant, conventional spectrum management approaches are unnecessarily rigorous and require expertise and effort. Advances in an autonomous, interference-tolerant concept have been made, based on a graceful frequency adaptation strategy. This has been found to be an efficient and robust basis for dynamic spectrum access in mobile radio networks. Spatio-temporal channel measurements and analyses were undertaken to support the investigations and to provide more realistic evaluations of adaptive capabilities and requirements. To respond to increasing demands on the limited available spectrum for military communications, it will be necessary to incorporate new strategies for spectrum access into the current spectrum regulatory, policy and management regime. The advances made within this
