Speed and heterogeneity in technological, social and structural changes having influence upon the battlefield nets create the need of constructing target conception of such a military telecommunication subsystem that could have be conducted for many years to come. Specifying the main trends in changes undergoing in analysed systems is the process leading to the defining of the future battlefield net structures. A particular attention was paid to the analysis of the results and conclusions from the research on development of battlefield net trends in the selected areas of their functioning. One of the development trends is a numerous collection of determinants affecting the planning and using of these military telecommunication nets. The basic determinants include mobility, information flow capacity, resistance to noise and jamming and security. The above factors were analysed, first of all, in aspect of using frequency ranges of the military communication systems. The results of this analysis may be useful for constructing the perspective battlefield net structures. These assumptions are based on two main levels - tactical range areas and higher levels of the battlefield nets command.
