The land change plan of Elon Musk Mackay daily mercury


A bold plan to cover the world with high-speed satellite internet may not be as crazy as it sounds and could be licensed to print money, according to a top Internet network expert.

The low latent routing in space, in which a satellite cluster of Earth's low orbit flashes wirelessly super-fast internet, sounds like more effort and expense than it deserves. But the idea has been explored to a great extent by Silicon Valley in recent years – and a man in particular wants to make it happen. And now you know him well.

He is controversial billionaire Elon Musk, whose private rocket company, SpaceX, wants to build a constellation of communication satellites as part of a project called Starlink.

The company received approval Friday by the Federal Communications Commission (FCC) to send an additional 7518 satellites to space as part of the ambitious plan, over 4400 already approved.

The core components of such a project have been done before, but certainly not to the extent that SpaceX would need Starlink to be successful.

Professor Mark Handley from the Department of Computer Science at London University College is a network topologist and recently wanted to create a simulation of how Starlink works.

"The devil is in detail and SpaceX seems to push the limits of what has been done on different fronts at once," he told news.com.au. But he believes the work is feasible.

Professor Hadley has captured the company's FCC submissions to get a general idea of ​​what SpaceX wants to do. The most interesting thing is that the company will probably be based on lasers instead of radio waves to receive messages between satellites, as it has not asked for any radio spectrum for satellite-to-satellite communication.

"We have usually assumed that by omitting any radio frequencies for in-satellite communications and discussing some optical communications components that may survive readmission," Prof Handley said. "This was then confirmed in additional FCC communications, but we do not know exactly how they intend to use laser links to connect the satellites together."

The video below shows how it may look like. Professor Handley said he used some educated guess and basic physics to "fill his gaps" of what could be feasible for SpaceX.


SpaceX has some of the most advanced rocket technologies in the world and its innovative reusable rockets will prove to be vital to Starlink. The missile system allows the boosters, which are usually discarded after one use, land safely on land and re-used for other launches.

"Without it, it's hard to see how that would be sustainable," Prof Handley said. "It is important to understand that they are not just building this time. Satellites have a lifespan of only five to seven years, so they consider the need to launch an average of two satellites a day on a continuous basis.

"They can, however, take about 25 to 30 satellites on a rocket, though much more if the next generation of BFR missiles is running so it's not as crazy as it could initially look like."

It is clear that SpaceX, which works closely with NASA, has the support of the US government.

"I'm excited to see what these services can promise and what the proposed constellations must offer," said FCC Ajit Pai president Friday after SpaceX has been approved to launch more satellites, provided it goes ahead with its plan.


In addition to providing Internet in virtually all corners of the globe, such a network provides a significant advantage – it can significantly reduce the delay in long-distance communications. This is because the free-space lasers communicate with the speed of light in a gap which is faster than the speed of light through the glass like that used in optical fiber optic cables on the ground.

And according to Prof Handley, there is a potential genius there.

He believes that something like Starlink could be extremely appealing to high-frequency dealers in large banks who may be willing to roll out for a speed advantage when it comes to trading on the stock market and stock markets.

It may sound like a strange idea, but the ability to shave milliseconds from the delay can be translated into large dollars for those businesses that are looking for an edge to be able to respond to the market faster than others.

Michael Lewis' book for 2014 Flash Boys records the rise of high frequency trading and begins to describe a $ 300 million project by Spread Networks – the construction of a 1331-kilometer cable that cuts through mountains and rivers from Chicago to New Jersey – with the sole aim of reducing transmission time for data from 17 to 13 milliseconds.

In theory, SpaceX could charge high premiums to access the ultra-fast Starlink network.

"I think it is the low-delay bonus that will be the one that makes the most money and its use by the financial industry will probably pay many bills," Prof Handley said.

"I think the social benefits of connecting remote sites will be enormous and will contribute to revenue, but if it was only for connecting remote sites, I do not think Starlink could pay for itself."

Professor Handley was in the US this week by presenting his research paper and worked on the Starlink simulation at a conference in Seattle.

"It may be amazing, not that many networking researchers are aware of Starlink plans," he said.

"It's not just about the existing space-based Internet – the rapidly changing nature of satellite routes poses all the interesting networking research questions and it will undoubtedly be of concern to networking researchers for many years."

Ultimately, he believes that such a network is inevitable. But if SpaceX is able to pull it off in years to come it remains to be seen.

Like all the other Musk has done lately, there will be no shortage of people to watch.
