Home Made Drone Beams Wi-Fi

//

Once the exclusive province of the military, drones now protect wildlife, study ancient ruins and could soon monitor storms. Robot enthusiast Adam Conway decided to add “Wi-Fi hotspot” to the list.

Conway, a product manager at Aerohive, which provides corporate IT networks, used a quadrotor frame, some plywood, and an old router from work to built a drone that can provide a Wi-Fi connection over the local LTE phone network. It can even link up to a corporate virtual private network for extra security.

Tasty Tech Eye Candy of the Week

He got the idea two years ago when the open source autopiloting program Adrupilot appeared. Conway had always been interested in robots, as it was his major in college. So he decided to build a drone, and then he had a conversation with a co-worker about what to do with it. “The guy said, ‘you have to put Wi-Fi on this drone,’” he told DNews.

After a few false starts — he crashed at least one drone and destroyed a router before he got it right — he had his Wi-FI-capable drone. The whole thing cost only a hundred dollars to build, and would only be twice that if he’d paid for the router.

The quadrotor is a fun platform, Conway said, but it isn’t that efficient as it can only stay up for a short time. He wants to build one that can hover for more than an hour, or have two in tandem that could provide continuous Wi-Fi service. To that end he might eventually go with a more airplane-like design.

More seriously, there are many uses for a Wi-Fi drone. Certainly in a post-disaster scenario, such as after a tornado or hurricane, it would help rescue workers to have internet and phone access in places where many cell towers are down. For ordinary people it would provide Wi-Fi in places where there just doesn’t happen to be a connection that can link to a corporate VPN, more than one road warrior would find that useful for the extra security, rather than trusting the hotspot at a Starbcks.

Disposable Drones Take Flight

For now though, he wants to have fun with it. “My goal is to provide Wi-Fi service at the next company picnic,” he said. “We haven’t been in places that let you fly remote controlled planes but I am lobbying for it.”
