This is a huge milestone on the way to help all people on the Internet."
Facebook will build thousands of network frame drones, and governments around the world and telecommunications companies, to the outskirts of the city and the country and the people in the disaster areas to provide Internet access service. You know, the current global 60 billion and there are still as many as 4016 million people living in remote areas without any mobile network cover.

"only the field of Internet communication, modern communication and network has ruled the world, open communication network environment becomes the key, the mobile Internet has entered the era of the people, the Internet is more widely laying imperative. Solar powered Internet Relay UAV will be low construction and maintenance cost for the air Internet signal to the large-scale land cover, change the mode of information dissemination, information rights, thus changing the world of Internet information model. A solar UAV Ground Station construction instead of air Internet Relay network, have epoch-making significance on the Internet more extensive application, will bring trillions of dollars in Internet market share, business prospects immeasurable.

"visible solar UAV to put into use as soon as possible, the key is to solve the problem of the solar cell. At present, like Facebook and Google UAV and other large market demand driven by the performance of a large number of new energy companies including hina film power, to further improve the battery is wildly beating gongs and drums. The chairman of the board of directors hina film power Li Hejun had previously said that the domestic solar market capacity is very large, only commercial UAV of this segment of the market capacity of more than one trillion yuan.
