The need for communication services varies within the battalion, where some services are to be distributed locally while others are to be spread throughout the entire battalion. At the same time, the requirements for robustness and jamming protection are generally high. The project Bataljonens radiokommu- nikation is a three-year project financed by the Swedish Armed Forces, that explores different solutions to meet the communication needs of a battalion. This report summarizes the project and the results obtained. To provide ar- chitecture and design guidance for tactical heterogeneous networks have been the focus of the NATO group IST-124-RTG-061 Heterogenous Networks - im- proving connectivity and network efficiency where the project has participated. Many of the issues within the project coincide with those of the NATO group. Within the IST-124, a scenario called Anglova consisting of three vignettes has been developed where FOI has contributed with vignette two. We have for that vignette investigated variants of OSPF, a standard protocol within IP, and found that the routing overhead becomes too high to handle the communication if all nodes belong to one and the same network. The projects has also investigated co-locations of both radio systems and networks. Results show that even for difficult interference situations in co-located networks, traffic can be delivered with a high probability, due to the inherent robustness of the networks. On the other hand, the interference caused a reduction in capacity in the networks as the number of relay-transmissions increased.
