Amazon’s upcoming satellite tv for pc broadband community, dubbed “Venture Kuiper,” simply handed a key check check that paves the way in which for a 2024 launch.
Just like SpaceX’s Starlink, Venture Kuiper is Amazon’s plan to supply high-speed web by launching and connecting 3,236 satellites in low Earth orbit (LEO). The agency launched two prototype satellites in October and started testing the techniques required for the community to function. One key check was validating the optical inter-satellite hyperlink (OISL) know-how, which makes use of infrared lasers to ship information between the spacecraft.
Now, Amazon says the prototypes have handed this vital hurdle. In testing, the 2 prototype satellites maintained a steady connection pace of 100 gigabits per second.

OISL has lengthy been used to keep up connections between satellites additional away from Earth. However earlier generations might solely hyperlink two satellites collectively. Past verifying the 2 satellites might preserve a high-speed hyperlink, extra information advised Amazon’s model of OISL ought to be capable of join its complete constellation of three,000-plus satellites collectively to create a mesh community.
At the moment, Earthbound optical fiber cables energy high-speed web companies by utilizing gentle to transmit information over nice distances. Venture Kuiper, nonetheless, transmits gentle in area, which travels 30% quicker than gentle racing via cables on Earth, based on Amazon. With OISL, Venture Kuiper will be capable of transfer information all through the community, that means it could actually obtain information from wherever on Earth and route it effectively based mostly on elements comparable to community site visitors.
It has all the time been tough to keep up OISL hyperlinks between satellites in LEO as a result of they require a particularly slender beam to be maintained over distances of as much as 1,600 miles (2,600 kilometers) and between satellites shifting at speeds as much as 15,000 mph (25,000 km/h). However the firm claimed its optics and management system have overcome these challenges.
Amazon goals to deploy sufficient satellites to start buyer pilots by mid-2024. Amazon plans for Venture Kuiper to supply speeds of as much as 400 megabits per second for many shoppers when absolutely deployed in 2029. That is roughly twice the common U.S. broadband pace, based on Speedtest. Some organizations can also be capable of faucet into speeds of as much as 1,000 megabits per second, based on the corporate. Whether or not the community will really attain such speeds when the system is absolutely operational in a real-world — and off-world — setting stays to be seen.
