SpaceX rolled-out Starlink beta internet service in northern United States and southern Canada in October. To date, SpaceX has deployed around 888 internet-beaming satellites out of the 4,409 that will operate in low Earth orbit. SpaceX is looking forward to connecting locations around the world where internet connection is unreliable and non-existent. Earlier this year, SpaceX engineers said Starlink is capable of beaming internet connection to remote areas on Earth; 60 Starlink satellites have the capability to beam low-latency, high-speed broadband internet to 40,000 users streaming high-definition videos simultaneously. Starlink customers receive service via a phased-array antenna dish and Wi-Fi router device. Additionally, SpaceX will build hundreds of ground stations that will receive the satellite’s communication. The stations are the linking factor between user terminals and data center for the Starlink network.
The Australian Communications and Media Authority (ACMA) which regulates telecommunications service, granted SpaceX a telecommunications license to offer internet on August 7th this year. SpaceX recieved approval to operate ground stations on October 26. ACMA granted SpaceX licenses to operate a total of 24 Starlink ground stations in Australia, according to a document published by the regulatory agency.
Approximately 2.5 million individuals in Australia still lack access to internet at home due to the service being either too expensive or unavailable in the rural location they reside in. Connecting rural areas around the globe to the network provides benefits to civilization as a whole. The Internet provides an equal chance for everyone to have access to education and job opportunites at their fingertips. Amid the Coronavirus outbreak, the digital divide among communites became more apparent, many students had to study from home but their households did not have internet service. SpaceX hopes to close the digital divide in rural areas worldwide. As more satellites are deployed to orbit, SpaceX will expand broadband coverage to Australia and the rest of the planet in 2021.
Evasive Maneuvers
In order to broadcast the 4G and eventually 5G signals, the satellites would come equipped with massive antennas up to 900 square meters in size. Given their planned proximity to other satellites, NASA says that’s a disaster waiting to happen.
“For the completed constellation of 243 satellites, one can expect 1,500 mitigation actions per year and perhaps 15,000 planning activities,” reads NASA’s statement. “This would equate to four maneuvers and 40 active planning activities on any given day.”
The unusual bright yellow creature, an albino Indian flapshell turtle, got rescued in West Bengal, India. And the internet thinks it looks like cheese, or an egg yolk.
The first quantum revolution brought about semiconductor electronics, the laser and finally the internet. The coming, second quantum revolution promises spy-proof communication, extremely precise quantum sensors and quantum computers for previously unsolvable computing tasks. But this revolution is still in its infancy. A central research object is the interface between local quantum devices and light quanta that enable the remote transmission of highly sensitive quantum information. The Otto-Hahn group “Quantum Networks” at the Max-Planck-Institute of Quantum Optics in Garching is researching such a “quantum modem”. The team has now achieved a first breakthrough in a relatively simple but highly efficient technology that can be integrated into existing fiber optic networks. The work is published this week in Physical Review X.
The Corona pandemic is a daily reminder of how important the internet has become. The World Wide Web, once a by-product of basic physical research, has radically changed our culture. Could a quantum internet become the next major innovation out of physics?
It is still too early to answer that question, but basic research is already working on the quantum internet. Many applications will be more specialized and less sensual than video conferencing, but the importance of absolutely spy-proof long-distance communication is understandable to everyone. “In the future, a quantum internet could be used to connect quantum computers located in different places,” Andreas Reiserer says, “which would considerably increase their computing power!” The physicist heads the independent Otto-Hahn research group “Quantum Networks” at the Max-Planck-Institute of Quantum Optics in Garching.
SpaceX’s Starlink satellite cluster has been receiving much headline space recently as it continues adding satellites at a breathtaking pace. Much of this news coverage has focused on how it’s impacting amateur skygazers and how it could benefit people in far-flung regions. But technical details do matter, and over on Casey Handmer’s blog, there was a recent discussion of one of the most important aspects of how Starlink actually operates—what will it do with its data?
In networking lingo, data is quantized into “packets,” which are sets of ones and zeros that computers can understand. In the case of Starlink, these packets will bounce between ground stations and a series of satellites parked in nine separate low-Earth orbits. Each orbit will contain a number of satellites, and each satellite’s covered territory will overlap with the satellites to the north and south of it. When the constellation is complete, every spot on Earth will be covered by at least two Starlink satellites.

It seems Starlink will give other service providers a run for their money. 🙂
Managing Expectations
SpaceX made its expectations clear from the beginning: The space company called the public test a “Better Than Nothing Beta” and suggested users might see speeds of 50 to 150 Mbps.

Initial commercial 5G mobile services were rolled out last year in South Korea, the United States, Australia, Britain, Switzerland, Spain and Monaco. Yet the scale of China’s market is likely to dwarf the combined size of those economies, negating any first-mover advantage.
While most people see 5G as a technical upgrade to 4G, the next-generation mobile system is expected to be a major building block of the fourth industrial revolution.
A few days ago, SpaceX started to offer Starlink satellite broadband internet service in areas located in the northern United States and southern Canada. With approximately 888 internet-beaming satellites in orbit the Starlink network is capable of providing ‘moderate’ broadband coverage. Early Starlink customers have shared photographs via social media of the Starlink Kit that is utilized to receive internet connection from the satellites in space. The Starlink Kit includes: “Dishy McFlatface” which is a 19-inch dish phased-array antenna, a mounting tripod for the dish, and an oddly-shaped Wi-Fi router device, pictured below.
