Drones are small flying machines. No pilot is on board. Drones can spy. They can attack. This is a danger. The firms Rheinmetall and Deutsche Telekom help. They build a new shield.
The shield protects important places. Examples are power plants. Examples are airports. Bridges and harbors also need protection. These places have the name critical infra-structure. The shield also stops hackers. Hackers attack computers.
Deutsche Telekom uses its mobile phone net. There are sensors on the masts. Sensors find the signals of drones. People find the drones early. Rheinmetall does the defense. It uses laser beams or blocking signals.
Many drones use a remote control. Some drones use the internet. Telekom finds these drones in the data. Both firms work together for a long time. They helped at the Football Championship 2024. They found forbidden flights there.
