The advantages of drones for WiFi include the ability to relocate them as needed and they present a moving target which is harder to shoot down. Balloons have the advantage of not requiring as much energy and maintenance. I guess both technologies risk tipping off the enemy as to the location of activities of interest. In that regard, using these technologies to expand WiFi in remote friendly territories is less problematic.
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
