The search for internet connection under extreme conditions

Abstract

EN: Learning during the war is very difficult, but it is possible. At this time we apply the knowledge and skills that we got before on practice. In February 2022 the city of Melitopol was occupied by Russian military forces. One of the problems in occupation has been the search of communication. Knowledge of physics and the probability theory came in handy. Of course, there are days, when there is neither communication nor electricity, or signal suppression devices are working. Before full-scale invasion into the city of Melitopol there were nearly 10 internet-providers working and three operators of mobile communication functioning. During the first weeks a few of them had stopped broadcasting, and in a few months the rest joined them. For a while it was possible to find communication. Now there are only three providers and two operators of mobile communication which work. But the quality of communication is poor.
