The International Conference on Military Communications and Information Systems ICMCIS will be held on 18 and 19 May 2015 in Poland in the city of Cracow. The conference was previously known as the Military Communications and Information Systems MCC. The conference is an established scientific event with a 22-year tradition. For the first time it took place in 1992 in Poland. The scope of the conference has been extended from national, then regional, to international (since 2006). The conference is held annually, alternately in Poland and in other European countries. In previous years it took place in Germany, the Czech Republic, the Netherlands and France. The following editions are planned for Belgium and Finland. Due to the fact that the conference has been shifted from autumn to spring, it will not be held in 2014. The conference has become an important forum for exchanging ideas and experiences in scientific circles that deal with military applications of communication and information systems. It is a platform for presenting the latest projects, based on NATO and EU programs, on the implementation of new technologies and services into military systems. The significance of the conference for this scientific environment is manifested in the support that has been provided for many years by the most prestigious institutions, such as: NATO Science & Technology Organisation, NATO Communications & Information Agency, European Defence Agency, The Institute of Electrical and Electronics Engineers IEEE, Armed Forces Communications and Electronics Association, Committee on Electronics and Telecommunication of the Polish Academy of Science.
