Higher-order effects of radiated interference-challenging research domains within EMC in future military dynamic wireless communication networks

The EMC area was once born in the 1920´s due to radio interference issues. In the near future, it is highly likely that radio interference issues once again will lead to several challenging new research domains within EMC. Examples of such domains are described and discussed in this paper. These domains require new analysis methods since the interference effects appear as higher-order effects on system-of-system level. One domain is the ongoing development of dynamic flexible wireless networks based on software defined radios (SDR) and cognitive radios (CR). Another one is a hybrid domain between the EMC area and the area of human factors, One vital combination is the use of commercial off the shelf (COTS) equipment in military wireless networks. COTS is allowed to radiate considerably higher levels of electromagnetic interference than military specified electronics. Examples of research results are given where analysis methods from wave propagation, intersystem interference and network management have been combined and further developed to analyze these new complex problems.
