If the current fails to be large, the mobile phone networks are not immediately paralyzed. For about half an hour, the systems can still send and receive before the emergency power battery also runs out of the juice. In an emergency, interruption -free communication is essential for the emergency services, civil protection and all those who work on the resolutions of the problem. An alternative would of course be to simply install larger batteries. But nobody wants large batteries in addition to transmission facilities, especially since they may never be used. The other method: You simply take one of the 240,000 electric cars traveling on Austria as a mobile battery for transmission systems.
