Google's giant balloons beam Wi-Fi from stratosphere




The first person to get Google Balloon Internet access this week was Charles Nimmo, a farmer and entrepreneur in the small town of Leeston who signed up for the experiment. Technicians attached a bright red, basketball-size receiver resembling a giant Google map pin to the outside of his home.


In a successful preliminary test, Nimmo received the Internet for about 15 minutes before the 16.5-metre-wide transmitting balloon he was relying on floated out of range. The first thing he did was check the weather forecast because he wanted to find out if it was a good time for “crutching” his sheep, or removing the wool around their rear ends.


Nimmo is among the many rural folk, even in developed countries, who can’t get broadband access. After ditching his dial-up four years ago in favour of satellite Internet service, he has gotten stuck with bills that sometimes exceed $1,000 a month.


“It’s been weird,” Nimmo said of the Google Balloon Internet experience. “But it’s been exciting to be part of something new.”


In recent years, military and aeronautical researchers have used tethered balloons to beam Internet signals back to bases on Earth. Google’s balloons would be untethered and out of sight, strung out in a line around the globe. They would ride the winds around the world while Google ground controllers adjusted their altitude to keep them moving along the desired route.


Ground stations about 60 miles apart would bounce Internet signals up to the balloons. The signals would hop backward from one balloon to the next to keep people continuously connected. Solar panels attached to the inflatables would generate electricity to power the Internet circuit boards, radios and antennas, as well as the onboard flight-control equipment.



Each balloon would provide Internet service for an area twice the size of New York City, or about 780 square miles, and because of their high altitude, rugged terrain is not a problem. The balloons could even beam the Internet into Afghanistan’s steep and winding Khyber Pass.
