Information superiority requires constant recognition of operational spaces because modern command and control need information flow from sensors to effectors. Such approach requires access to services for mobile users. Moreover, the sensors become a part of the radio network, too. Currently, armed forces are providing troops with personal radios. This requires more frequencies available for the radio networks to operate, which means that an electromagnetic warfare starts at the lowest level of an echelon. A traditional frequency access becomes inefficient. A dynamic spectrum access is believed to increase capability of frequency usage. A dynamic spectrum access implementation needs cognitive radios which can monitor the spectrum. The cognitive radio uses information about the spectrum to prepare a plan of action in case of some interference. A knowledge about current situation within the cyberspace could also be used by other systems (e.g. electromagnetic warfare system). The article presents the capability of cognitive radios and highlights advantages resulting from a connection between radio and electromagnetic warfare systems. The paper emphasises certain risks associated with a lack of connection between radio communications and electromagnetic warfare systems.
