Google Inc. plans to spend more than $1 billion on a fleet of satellites to extend Internet access to unwired regions of the globe, people familiar with the project said, hoping to overcome financial and technical problems that thwarted previous efforts.

Details remain in flux, the people said, but the project will start with 180 small, high-capacity satellites orbiting the earth at lower altitudes than traditional satellites, and then could expand.

Google's satellite venture is led by Greg Wyler,founder of satellite-communications startup O3b Networks Ltd., who recently joined Google with O3b's former chief technology officer, the people said. Google has also been hiring engineers from satellite company Space Systems/Loral LLC to work on the project, according to another person familiar with the hiring initiative.

Mr. Wyler has between 10 and 20 people working for him at Google and reports to Craig Barratt, who reports to Chief Executive Larry Page, one of the people said. Mr. Wyler couldn't be reached.


The projected price ranges from about $1 billon to more than $3 billion, the people familiar with the project said, depending on the network's final design and a later phase that could double the number of satellites. Based on past satellite ventures, costs could rise.

Google's project is the latest effort by a Silicon Valley company to extend Internet coverage from the sky to help its business on the ground. Google and Facebook Inc. are counting on new Internet users in underserved regions to boost revenue, and ultimately, earnings.

Google's Project Loon is designing high-altitude balloons to provide broadband service to remote parts of the world. In April, Google acquired Titan Aerospace, which is building solar-powered drones to provide similar connectivity. Facebook has its own drone effort.

"Google and Facebook are trying to figure out ways of reaching populations that thus far have been unreachable," said Susan Irwin, president of Irwin Communications Inc., a satellite-communications research firm. "Wired connectivity only goes so far and wireless cellular networks reach small areas. Satellites can gain much broader access."

Google's efforts to deliver Internet service to unserved regions—through balloons, drones and satellites—are consistent with its approaches to other new markets. Even if one or more projects don't succeed, Google can often use what it learned in other areas.

A Google spokeswoman said the company is focused on bringing hundreds of millions of additional people online. "Internet connectivity significantly improves people's lives. Yet two thirds of the world have no access at all," she said. She declined further comment.

Tim Farrar, head of satellite-consulting firm TMF Associates, expects Project Loon's balloons eventually to be replaced by Titan's drones. Drones and satellites complement each other, he said, with drones offering better high-capacity service in smaller areas, and satellites offering broader coverage in areas with less demand.

Mr. Farrar worked as a consultant for Teledesic LLC, which tried to build a constellation of low-earth-orbit satellites to deliver Internet service in the 1990s. Teledesic, backed byMicrosoft Corp. and telecommunications entrepreneur Craig McCaw, considered using drones to provide additional capacity for the satellite system in some areas, he said. The more than $9 billion project halted satellite assembly in 2002 amid technical hurdles and cost overruns.

Earlier, Iridium Satellite LLC went into Chapter 11 bankruptcy reorganization less than a year after starting voice and data services in 1998.

History is replete with ambitious satellite plans that failed, according to Roger Rusch,who runs TelAstra Inc., a satellite-industry consulting firm. Google's project will end up "costing far more than they can imagine today," he said, perhaps as much as $20 billion. "This is exactly the kind of pipe dream we have seen before."

Google also will have to overcome regulatory hurdles, including coordinating with other satellite operators so its fleet doesn't interfere with others.

O3b, in which Google was an early investor, has been working on providing broadband Internet connectivity from satellites weighing about 1,500 pounds each. O3b has been planning to launch about a dozen satellites, aiming to serve large areas on either side of the equator.

Google hopes to cover the entire globe with more, but smaller, satellites weighing less than 250 pounds, the people familiar with the project said.

Jamie Goldstein, an O3b director and a partner at North Bridge Venture Partners, which backs the company, said he couldn't comment on what Mr. Wyler is working on, citing a nondisclosure agreement with Google. An O3b spokeswoman didn't respond to requests for comment.

During a conference in March, Google CEO Mr. Page mused about spanning the globe with Internet access delivered by Project Loon. "I think we can build a world-wide mesh of these balloons that can cover the whole planet," he said, noting that they are cheaper and faster to launch than satellites.

But satellites are more flexible and provide greater capacity. In recent years, costs to build and launch satellites have dropped sharply, according to Neil Mackay, CEO of Mile Marker 101, an advisory firm.

Consultant Mr. Farrar estimated that 180 small satellites could be launched for as little as about $600 million.

If Google succeeds, it "could amount to a sea change in the way people will get access to the Internet, from the Third World to even some suburban areas of the U.S.," said Jeremy Rose of Comsys, a London-based satellite consulting firm.

Google also is hoping to take advantage of advances in antennas that can track multiple satellites as they move across the sky. Antennas developed by companies including Kymeta Corp. have no moving parts and are controlled by software, which reduces manufacturing and maintenance costs.

Kymeta hopes to sell its ground-antenna systems for hundreds of dollars, said CEO Vern Fotheringham. They would substitute for phased-array antennas which cost roughly $1 million a decade ago, he said.

Kymeta supplies antenna technology for O3b and worked closely with Brian Holz, a former O3b chief technology officer. Mr. Holz recently joined Google's satellite project, along with Mr. Wyler and David Bettinger, technology chief of satellite-communications company VT iDirect Inc., Mr. Fotheringham said.

Technology news website the Information reported on May 27 that Google had hired Messrs. Holz and Bettinger for a satellite project.

"Google certainly has the resources to do something exciting in this area," Mr. Fotheringham said. "We and everyone else in the industry are keen to hear more about what they're working on."

Google wants to bring free wifi to the world…. and it's starting NOW. Matt Payton for Metro.co.ukThursday 25 Jun 2015 12:57 pm. 85.4k. Google wants to bring ...

谷歌將向全球提供免費無線網絡(Wifi)服務,中國網絡防火牆將被推倒

美國西部時間2016年3月27日4點30分,搭載6顆谷歌衛星的運載火箭發射升空,谷歌的全球免費無線網絡(Wifi)覆蓋計劃邁出了第一步,預計今年之內將有超過60顆衛星升空,初步實現全球免費無線網絡覆蓋。
據美國《看中國》網站引述網絡消息報導:谷歌通過數百顆衛星向全球提供的免費無線網絡服務,無盲區、無死角:任何人不管身處高山、大漠、冰凍極地還是浩瀚海洋,只要有一部由電池供電的路由器般大小的價值不過幾十美元的中繼轉發器,便可以通過帶無線網絡功能的設備上網。
一旦谷歌全球免費無線網絡服務開通,中國政府花費巨資建造的把本國互聯網與世界互聯網隔開的網絡防火牆,就將被推倒,取而代之的是全球網民使用最多的“whats app”。Whats app系統功能強大,可以接通谷歌、臉書、推特和所有國外網絡。
網絡的新一波革命也將隨著谷歌的這一計劃實施而發生:手機微信被取代,有線光纖受到衝擊,台式電腦的無線網卡被普遍應用,平板與筆記本電腦迎來新的銷售高潮。
六年前谷歌因遭受中國黑客攻擊和拒絕中國政府的網絡審查而退出中國,隨之被阻擋在中國網絡防火牆之外。不久的將來,谷歌將隨著全球無限網絡重臨中國,中國網民將唾棄屏蔽中共不喜歡的敏感信息、只提供不完全信息的百度搜索,而重新享用谷歌搜索。
《看中國》報導了一些網民對谷歌向全球提供免費無限網絡服務的反應,有網民說:“谷歌怎麼老是和獨裁專制過不去,這不是要黨的命嗎?”
