A Simulation of the SpaceX, Amazon, Telesat and OneWeb Broadband Satellite Constellations

Over two years ago, an MIT research group ran a simulation of the low-Earth orbit broadband constellations of OneWeb, SpaceX, and Telesat, and last January they repeated the simulation updating with revised constellation characteristics and adding Amazon's Project Kuiper. They ran the new simulation twice, once using the planned initial deployments of each constellation and a second time using the configuration shown. more

A New Chinese Broadband Satellite Constellation

In an earlier post, I described three Chinese low-Earth orbit (LEO) satellite constellations that seemed to be oriented toward broadband communication... None of those companies seem to be pursuing the global consumer market that SpaceX and OneWeb hope to serve, but a new Chinese company code-named GW seems to plan on doing so. more

Google DNS to Be Discontinued in Brazil Ahead of New Law

Doug Madory from Renesys reports: "In response to recent NSA spying allegations, Brazil is pressing ahead with a new law to require Internet companies like Google to store data about Brazilian users inside Brazil, where it will be subject to local privacy laws. The proposed legislation could be signed into law as early as the end of this week. However, Google's DNS service started leaving the country on September 12th, the day President Rousseff announced her intention to require local storage of user data." more

YouTube’s Fine - Analysts Don’t Understand Internet Peering

As widely reported, Credit Suisse analysts have estimated Google's YouTube may lose $470M in 2009 and more in the future. However, their estimates say Google will pay $360M for bandwidth in 2009. I don't know how Google figures their cost of bandwidth, but anyone who understands anything about Internet transit/peering knows Credit is way off base. more

The Internet: Missing the Light

Today's Internet is wonderful for solving hard problems such as connecting to Amazon to buy goods or for using Netflix. Amazon and Netflix, among others, demonstrate what is possible if you put in enough effort. Yet if we are to understand the Internet we need to look beyond those applications to the simplest application such as sending one bit of information from a light switch to a light fixture. more

Why Satellite Cellular Won’t Replace Traditional Cell Networks Anytime Soon

There was a burst of recent press about cellular service provided from satellites. This was probably prompted by the two recent hurricanes that have disabled terrestrial cellular and broadband networks in the southeast. I've seen speculation and discussion on Reddit and other forums where people have been wondering if satellite is the future of cell service and if the ubiquitous giant cell towers will eventually become obsolete. more

Two New Chinese Internet Service Constellations and Their Market

China’s plans for low-Earth orbit Internet service constellations began with two projects, Hongyun (156 satellites) and Hongyan (864 satellites). These were eventually sidelined for Guowang, an ambitious, 12,992 satellite constellation that is expected to begin launching satellites this year. But, that is old news. China’s five-year plan designates satellite Internet as a strategic emerging industry and two new constellations have emerged, G60 (12,000 satellites) and Honghu–3 (10,000 satellites). more

Simulation of OneWeb, SpaceX and Telesat’s Proposed Global Broadband Constellations

Inigo del Portillo and his colleagues at MIT have run a simulation comparing OneWeb, SpaceX and Telesat's proposed low-Earth orbit Internet service constellations. The models are based on the initial FCC filings by the companies and demand and data-rate estimates by the authors. I will mention subsequent amendments to the filings below later in the post. more

The Internet is Dead - Long Live the Internet

Back in the early 2000s, several notable Internet researchers were predicting the death of the Internet. Based on the narrative, the Internet infrastructure had not been designed for the scale that was being projected at the time, supposedly leading to fatal security and scalability issues. Yet somehow the Internet industry has always found a way to dodge the bullet at the very last minute. more

Internet Traffic Growth Rate Falling by Half in U.S. According to Cisco VNI

In 2014, Cisco estimates Internet traffic growth in the U.S. will be less than 18%, far less than most previous estimates. Worldwide, they measure the current rate at 42% and expect that to fall to 30% in four years. Actual numbers at Cisco Visual Networking Index (VNI) is the definitive source on Internet traffic today because they have direct relationships with carriers from China Telecom to AT&T. Their future estimates are the most carefully done publicly available. more

Exploring the Roots of Wireless Spectrum Controversy (eComm Panel)

Earlier this month, I had the opportunity to attend the The Emerging Communications (eComm) 2009 conference in San Francisco which was packed with 3 days of fascinating conversations about the future of communications. I absolutely enjoyed talking to various speakers and attendees giving me a deep level of appreciation and perspective on technical, commercial and political issues at hand -- and what is likely to come in the next few years. And speaking of politics, Lee Dryburgh, who founded eComm in early 2008, has generously allowed us to share with you a fascinating panel discussion which took place on day 3 of the conference called "Spectrum 2.0 - What's really happening?" more

Guowang, Renamed China SatNet, Will Be China’s Global Broadband Provider

In an earlier post, I described what looked like two forthcoming Chinese broadband constellations, Hongyun and Hongyan and in another post, I described a third, identified as "GW" at the time. All three were projects of state-owned enterprises China Aerospace Science and Technology Corp. (CASC) and China Aerospace Science and Industry Corp. (CASIC). There was pushback from those contending that a broadband constellation was redundant ... more

Inter-Satellite Laser Link Update

Inter-satellite laser links (ISLLs) and electronically steerable flat panel antennas are critical technologies for constellations of low-Earth orbit (LEO) Internet-service satellites. Low-cost antennas are critical for the mass consumer market, and ISLLs are required for an effective Internet backbone in space. In an earlier post, we saw that progress is being made on antennas; this one looks at ISLLs. more

Who is Blocking WHOIS?

On April 16 ICANN issued a breach notice to Turkish Registrar Alantron for not consistently providing access to its WHOIS database via Port 43, a command-line query location that all Registrars are required to supply under conditions of their contract with ICANN under section 3.3.1. Four days later they issued a breach to Internet Group do Brazil for the same problem. ... The WHOIS record, as we all know, is a massive fraud with illicit parties filling records with bogus information and hiding behind anonymity. more

Internet Governance Outlook 2018: Preparing for Cyberwar or Promoting Cyber Détente?

In 2018, Internet Governance will be one of the top priorities in the geo-strategic battles among big powers. In today's world, every global conflict has an Internet-related component. There is no international security without cybersecurity. The world economy is a digital economy. And human rights are relevant offline as well as online. It is impossible to decouple cyberspace from the conflicts of the real world. more
