Listen to Dr. William Conley talk about the RF spectrum (part of the electromagnetic spectrum or EMS). Learn why domains are really about joint command relationships and not fundamental physics. Dr. Conley will discuss why every service has to have some core capability in this part of EMS because all multi-domain operations, including space, depend on the spectrum to coordinate capabilities. Electromagnetic battle management tools can impact spectrum management because they have the ability to dynamically shift what we are doing in the spectrum. The advent of software defined radio technology is giving even greater ability to manage these devices so that they operate in coordination with each other. Learn how the convergence of electronic warfare and cyber capabilities are presenting new challenges and opportunities. Our way of war assumes a level of spectrum access allowing us to fight in the way we want; however, that ability may be changing.
