Deutsche Telekom and Rheinmetall are collaborating to create a 'defence shield' against drones and sabotage, aiming to protect German cities and critical infrastructure. This initiative responds to a rise in drone incursions in Europe. The system will utilize sensors and jamming technology to detect and neutralize drones, with potential applications of laser technology. Recent statistics show over 1,000 suspicious drone flights reported in Germany last year. The companies are also adapting detection systems for drones controlled via mobile networks, with ongoing research at Helmut Schmidt University.
