Topic Reading-Vol.2221-5/11/2018

Dear MEL Topic Readers,
Drones to the rescue!
Drones are no longer just a tool of the military, business, entertainment or art. Though conventional drones can fly only for a limited time because of the battery capacity, there are some ways to make them provide essential services in an emergency or extraordinary situation.
For example, if a drone is wired to the ground to be powered, it can fly 24/7 to provide internet connection in an area where signals are too weak or unavailable. Another idea is to fly multiple drones around a building on fire each of which has a different role to play, such as providing internet connection, visual images of the site, and thermal data of the burning building. Why not just one drone to do all the tasks? That’s because the lighter the drone is, the longer the operational time could be. Also, drones can complement or augment an existing connection service when it is overburdened, such as during a sports game or a music concert where tens of thousand people try to be connected at the same time.
Enjoy reading and learn what roles drones are and will be playing in the backyard.
