The core problem for using drones in automated jobs by commercial companies is how to ensure communication with drone in urban areas.
Conventional drone remote controllers can ensure the transmission of radio waves in urban conditions up to a distance of 300m. In this case, the greatest benefits of drones are limited: quickly gain an overview of large areas, transfer video and work within a radius of up to 10 km. At the same time, almost all cities in the EU Member States have very good 4G mobile coverage. It is also planned to roll out 5G services in most EU cities by 2023 at the latest. In Germany, for example, 5G coverage is already guaranteed to 70% of the population by 2021.
That’s why CAFA Tech offers drones with a 4G/5G module, which can be used to fly farther in urban conditions, even 10-20 km, because there are no limits to mobile coverage!
Various measurements have shown that good mobile communication coverage is also available at an altitude of 100m AGL (Above Ground Level), because the residents of a 30-storey house also need mobile communication!
