While competing with other tech giants in providing internet access to the far away reaches of the world, Facebook seems to be interested in unmanned technological innovations. In fact, it seems to be interested in flying drones!

That's right if all things fall in place, the skies above Facebook's headquarters could be buzzing with the noise of miniature aerial vehicles.

Facebook is interested in flying a miniature wireless beaming drone, 400 feet above its headquarters in the near future. The organization has asked for permission to operate an experimental radio in 2.4 GHz range according to recently filed documents with Federal Communication Commission (FCC).

According to the filings, the purpose of this "Special Temporary Authority" request is for testing new communication applications and devices in a controlled, low-altitude airborne environment. Another filing stated that the test environment is located in the city of Menlo Park, California.

The filings were made by Facebook under its FCL Tech drone subsidiary. The technical specification and other related features of Facebook's drone remain confidential.  

Meanwhile, Business Insider reported that Facebook is focused on creating solar-fuelled Aquila drones to provide internet access to different parts of the globe. These drones, however, seems to be large and devised to fly at an altitude of 60000 feet for up to two-three months at a time.

The test environment for these large drones is reportedly in Arizona. The interest in flying miniature gadget-sized drones in Menlo Park, California may not mean that Facebook is looking for an innovative set of drones. It is highly possible that these smaller drones would be used to test wireless technology which could be incorporated in the larger Aquila drones.

A Facebook spokesperson decline to comment on these developments when contacted by Fortune.

In an earlier note to the FCC, Facebook requested for privacy on certain items like its test plan and vendors of the components. The company noted that the disclosure of this information would significantly disadvantage the competitiveness of FCL, especially when it comes to the communication services.

At the moment, Facebook's request to test its wireless networking technology is pending the approval of the FCC.
