Google has started secretly testing its balloons over Nevada for its "Project Loon" initiative. In addition, the search giant has also purchased drone company Titan Aerospace to beef up the technology for the said project, according to VentureBeat.

Project Loon is Google's new initiative to bring the Internet to remote regions in the world that are still offline using high-altitude balloons. The project was revealed in June 2013 but up until now, the firm has not shown any visible updates about it. Only informative videos about the project were released. Google plans to fly solar-powered balloons spanning 15 meters and use them to deliver Internet signals to the desired areas. These balloons could fly for 100 days and are capable to delivering signals with similar speeds to 3G, the report explained.

PC World reported that Google has started conducting trials over the desert of Nevada. It had also asked permission form the Federal Communications Commission (FCC) in September to use radio spectrum for 4G LTE for the tests, the report added.

In November, Google was granted permission by the FCC to conduct the trials in northern Nevada, according to PC World. Public advisories were released to inform about the launching of six high-altitude balloons in the sad area, VentureBeat reported.
