SWING (Short Wave critical Infrastructure Network based on a new Generation high survival radio communication system) is a European project aimed at studying a high survival HF radio network to link European Critical Infrastructures (ECIs) among themselves.
This system is thought to replace broad band internet transmission, maintaining the minimum flux of essential information for the ECIs management and control, in case of wide scale terrorist attacks able to put out of order internet links over the Mediterranean region.
SWING is designed to evaluate the threat and increase the security awareness, as well as the level of protection, of analogous and/or interdependent ECIs.
In order to meet these goals SWING has to recognize how and when the internet communication fails and develop the standard software and hardware tools necessary for implementing communication protocols suited for a reliable and interoperable Short Wave (High Frequency) radio network back up.
To meet the above mentioned objectives the main activities concern the designation of ECIs in the regions of interest and the analysis of potential communication problems among them, followed by the identification of the most suitable topology for a high survival radio communication network.
Moreover, SWING has to determine the criteria for early warning alerts, the procedures to activate the backup network, as well as the minimal amount of information necessary to maintain control over ECIs keeping them linked even in critical conditions.
For what concerns the HF radio network, SWING defines and designs the software and hardware necessary to a high survival HF radio network, keeping into account the existing HF network communication protocol and architecture.
Since the network can use both the ionospheric channel and, if required, the ground wave propagation, SWING also studies the ionospheric channel characteristics in order to manage the transmission frequencies of the HF network
