Finnish telecommunications company Nokia may have been founded in 1985, but it's continuing to explore new territory as a business. For example, most telecom companies inspect their cell towers using human labor, a practice that can sometimes have tragic consequences. But more and more companies--Nokia among them--are piloting the use of drones to quickly and safely inspect cell towers. In 2015, Nokia Networks used "Telco" drones equipped with cellphones to not only inspect its towers in Dubai, UAE, but to make sure there was a proper line of sight between radio towers and ensure that the optimum frequencies are being sent between towers. This new method of inspection drastically cuts inspection time, is cost-efficient, and above all, protects human lives. The company hasn't announced how widespread drone implementation will be, but reported positive results from the pilot test.
