Abstract

This report summarizes the first year of activities carried out within the 3 year project RICOM (Robust Integration of Wireless Telecommunication System). The project will mainly study improved methods for system integration on platforms. The methods must take into account the tactical behaviour, communication services, electric-mechanical constraints, inter-system interference and warfare aspects on the platform. The concept robustness is used in the meaning of robustness to electromagnetic interference, absence or varying coverage of infrastructure or telecommunication services and varying radio channel or receiving conditions of the radio communications. The project has been prioritized on both scientific publishing and continuous interaction with customer representatives. By conducting interviews and by analysing lessons identified/lessons learned, several examples were collected for the further work of identifying the causes of increased risk of inter-system interference and lack of co-existence between systems on platforms. Furthermore, a study of methods for increased robustness for satellite-communication systems has been performed, as well as a method for optimal use of available spectrum at the high frequency (HF) band has been further developed. Key findings from the work 2014 are:  Increased knowledge is needed, to be able to quantify the benefits and the economic costs of specific actions that are proposed to solve collocation problems  There is a lack of guidelines and underlying user needs for the use of satellite communication in the Swedish Armed Forces today. In the absence of guidelines and user needs, the current robustness requirements of the satellite communication systems are unclear  Performance enhancement in the form of, for example, higher data rates or less retransmissions can be achieved by using a method for improved frequency selection and power allocation that utilizes information about the interference environment on the receiver platforms In the autumn of 2014, a two-day workshop has been conducted in Karlskrona with 65 participants. The goal of the workshop has been to create an annual forum for knowledge transfer between research and specific operational needs in order to better manage and fix future transmission and communication problems related to integration and interference issues.
