Methods for intersystem-interference analyses in dynamic wireless communication networks

The Swedish Defence has a need of developing new analysis methods for intersystem interference. FOI performs a number of research activities in order to support this development by ensuring that new dynamic communication systems can be handled in a future analysis tool. A key issue is the ability to consider the total electromagneticinterference environment within the receiver band of a wireless communication system. Furthermore, to determine what consequences intersystem interference could have on the network level of a wireless communication network. The method based on only using the total average interference power is investigated to see if the uncertainties connected with this method are small enough when conclusions on the network level in an ad hoc network are to be drawn. Furthermore, the commercial network analysis tool OPNET Modeler is investigated to see if that tool is a convenient software environment for a new analysis tool. Finally it is investigated how an operators ́trust could be affected by intersystem interference in a communication network. The results show that the total average power is useful if a proposed correction factor is used to eliminate the largets uncertainties. It is also shown that OPNET Modeler is a possible candidate as a basic software environment for a future intersystem-interference analysis tool for defence applications. It is also shown that intersystem interference, in some cases, severely can affect a commanders ́situation awareness and trust.
