Awareness of risks and the need to prevent them is therefore becoming increasingly important in our society. At the same time, it is essential to build the capacity of the state, the economy, and the population to prepare for hazardous situations and deal with the consequences. Crises and disasters can only be prevented by the interaction of governmental and non-governmental actors from different disciplines and levels of action, and managed by pooling all available resources.

Many governments are therefore pursuing a comprehensive, networked approach. Such a resilience strategy formulates goals and measures for such a path. It is intended to contribute nationally and internationally to strengthening resilience to disasters.

Centralized and decentralized – In decentralized networking, the communication points speak directly to each other. With centralized networking, the communication points do not talk directly to each other, but via a so-called HUB. This significantly reduces the number of interfaces required.

Decentralization means spatial separation – If the redundant systems are not independent and separate from the standard supply system, there is an increased risk. This also means a corresponding spatial separation or mobility of the systems. The diversity of systems, channels, and also locations contributes significantly to the redundancy and resilience of communications. In the event of an emergency – whether a blackout, regional power failure, natural disaster, or terrorist attack – rescue and security forces must be able to be reliably alerted and must be able to use the same systems to handle communications during operations.

A second infrastructure is therefore advisable, that much has been recognized in each case. It is safer if this infrastructure is also structured differently. The decentralized structure is the magic word here which promises additional security. In addition, it is exciting if the time infrastructure succeeds in integrating the primary paths such as fixed network telephony or mobile telephony. The result is a three-dimensional and resilient communication infrastructure.

Example: What we learn from guerrilla tactics for communication.
The term guerrilla or guerrilla warfare originally comes from Spanish and means small-scale warfare, a military fighting unit. Its first significant use was in the resistance struggle against Napoleon. Guerrilla warfare is fought between unequal opponents.

It is important to us: we do not advocate war and we are explicitly against it. However, lessons should be learned in every respect. In the case of guerrilla tactics, it is also this that these decentralized groups have high resilience. Even if one group fails, the larger whole continues to function. This also applies to the continuation of the communication channels. This is exactly where we can start with our learnings. Modern communication in tactical units can be set up exactly according to this pattern. Vulnerable headquarters and central offices are increasingly superfluous.
