Facebook Shows its Connectivity Lab

Facebook posted a video tour of its Connectivity Lab, showcasing progress it has made in developing an ultralight drone aircraft that will stay aloft for three months at a time at altitudes of 30km.

The project aims to deliver Internet services in regions that are currently underserved.  The plan is to use a 100 Gbps free-space laser for backhaul link from aircraft to the ground.  Wi-Fi towers on the ground will provide local coverage. Test flights are expected to begin later this year.
