In Scotland's rugged hills, where mobile phone signal is often patchy, accessing help in emergency situations can be a daunting challenge. However, a groundbreaking trial in Tarfside, Angus, is aiming to revolutionize rescue efforts by testing the feasibility of deploying pop-up mobile phone networks using drones. This innovative approach not only addresses the communication hurdles faced in remote areas but also enhances the efficiency and effectiveness of mountain rescue operations.
