Samsungs giant satellite network could enable high-speed internet access across the globe
DARIO BORGHINO SEPTEMBER 14, 2015 5 PICTURES
A highly ambitious proposal recently advanced by Samsung describes the deployment of a huge network of 4,600 near-Earth satellites that would provide internet coverage on a truly global scale. The artificial constellation would more than double the number of working satellites in orbit around our planet and lead to low-latency and (potentially) low-cost access to about 200 GB of internet traffic a month for up to five billion people, no matter their locatin.
Recent studies estimate that as many as 4.2 billion people, over 60 percent of the worlds population, still lack internet access. Bringing the Web to every corner of the globe is sure to be a huge undertaking, but the repercussions of, say, bringing freedom of information and low-cost access to high-quality education materials to anyone who can put their hands on a cheap smartphone would surely bear consequences worth noting.
Samsung is not the first to advance such an idea. Google has been among the pioneers in this field, initially turning to hot-air balloons and then, more recently, partnering with SpaceX to deploy their own satellite constellation. Facebook has also unveiled plans including the use of solar-powered drones, and Richard Bransons OneWeb satellite network is yet another major contender.
Samsung expects global monthly data demand to increase more than a hundred-fold and reach the staggering figure of one zettabyte (one billion terabytes) by the year 2028. Since putting in place a complex infrastructure of communication satellites is sure to take several years, the emphasis with the electronics giants approach is an aggressive attempt to get the most bang for the buck in terms of bandwidth, and to do so in the largest possible scale.
Communication satellites usually operate in a geostationary orbit, about 36,000 km (22,000 miles) from the surface. In this orbit, satellites remain at a fixed point in the sky when seen from Earth, so their data can be accessed with relative ease through a small, stationary dish. Samsung, however, reasoned that this wouldnt do for satellite-based internet, since at such a high altitude radio signals would take about a quarter of a second for a round-trip, too long for practical applications.
Samsungs plan is to instead have its satellite fleet operate much closer to Earth, around 1,400 km (900 miles) above the surface. And because radio signals in space can travel in a straight line, as opposed to signals in fiber optics (which travel by constant zig-zagging as the signal is reflected from one side of the cable to the other), Samsung says that its network would actually provide lower latencies for medium and long distance communications.
Geostationary orbits are also often used for convenience, since the entire surface of the globe can be covered with as few as three satellites. Samsung, however, plans to turn this dynamic on its head, attempting to cut costs by mass-producing a giant fleet of 4,600 low-cost satellites each able to provide data rates in the terabit range. Besides the cost savings, such a large fleet would also offer more flexibility, providing higher capacity over more densely populated areas.
As of now there are no definite plans attached with Samsungs proposal, but given the amount of interest shown from competing companies, it wouldnt be a stretch to assume that large scale satellite-based internet has an increasingly high chance of becoming a reality. When this might finally happen, and who will be the first to achieve this milestone, still remains to be seen.

이걸 믿는애들은 진짜 공부안하고 다녓나;; 무슨 삼성이 위성을쏴..
출처도없고. 삼성이 위성쓸정도로 5억의 인구가 인터넷을? 뭔 개소리여;;
네이버에 한국위성이라도 쳐봐라

ㅋㅋㅋㅋㅋ 뭔소린지는 모르겠고 언제될지도 모르겠지만 아무리 자본력차이가 난다고해도 이게된다면 KT,SK,LG 통신사가 한순간에 벼엉신이 되는데 이게 가능할꺼라고 생각함? 5억인구라고하면 무선으로 전세계 유무선 통신계를 평정하겠다는 소린데 말도 안되는 소리임 ㅋㅋ
아니 ㅋㅋㅋㅋ 우리나라 위성도 러시아 애들이 와서 맨들고 쏴주는판에 무슨 삼성이 무슨 위성을 쏴서 5억명이 어쩌구 저쩌구여 ㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋ 어디서 이상한글 들고와서 ㅋ
