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
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
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
Annual global IP traffic will pass two-thirds of a zettabyte in four years according the Cisco's Visual Networking Index report. The economic downturn has only slightly tempered traffic growth and the global IP traffic is expected to quintuple from 2008 to 2013. Cisco predicts IP traffic to grow at a compound annual growth rate (CAGR) of 40%. more
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
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
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
As someone closely involved with the Australian National Broadband Network (NBN) and many other fibre plans around the globe, I would like to provide an inside picture of the revolutionary developments that are taking place in the Australian broadband market. Australia's national broadband network will be an FttH-based open wholesale network -- a network that will connect (not pass) 90% of all Australians to fibre, with the remaining 10% of the population being linked to that network through technologies that are capable of delivering equivalent services. more
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
Comcast's furtive and undisclosed traffic manipulation reminds me of a curious, red herring asserted by some incumbent carriers and their sponsored researchers: that without complete freedom to vertically and horizontally integrate the carriers would lose synergies, efficiencies and be relegated to operating "dumb pipes."... Constructing and operating the pipes instead of creating the stuff that traverses them gets a bad rap. It may not be sexy, but it probably has less risk. But of course with less risk comes less reward, and suddenly no one in the telecommunications business is content with that. So incumbent carriers assert that convergence and competitive necessity requires them to add "value" to the pipes. more
Last May, SpaceX founder Elon Musk tweeted "6 more launches of 60 sats needed for minor coverage, 12 for moderate" and SpaceX President and CEO Gwynne Shotwell recently said they planned to be offering service in parts of the US in mid-2020, which would require six to eight 60-satellite launches. The first of those launches will be in the middle of this month on a thrice-flown Falcon 9 booster. (They will also need customer terminals and Elon Musk has used a prototype to post a tweet from his home). more
In 1990, Teledesic was formed to deliver satellite-based Internet service. Cellular pioneer Craig McCaw, Microsoft co-founder Bill Gates and Saudi Prince Alwaleed bin Talal were early investors and Boeing was both an investor and the prime contractor. Teledesic hoped to offer global Internet connectivity using a constellation of 840 satellites in low-Earth orbit (LEO) at an altitude of 700 km... Teledesic failed. Twenty seven years later three companies SpaceX, OneWeb and Boeing are trying to do what Teledesic could not do. Will they succeed? more
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
I've been following the efforts of SpaceX and OneWeb to become global Internet service providers using constellations of low-Earth orbit (LEO) satellites for some time. Launch times are getting close, so I'm posting a status update on SpaceX's project... The Senate Committee on Commerce, Science, and Transportation held a hearing titled "Investing in America's Broadband Infrastructure: Exploring Ways to Reduce Barriers to Deployment" on May 3, 2017, and one of the expert witnesses was Patricia Cooper, SpaceX Vice President, Satellite Government Affairs. more
Is it just a coincidence that some of the leading Internet-based application companies are pushing aggressively into network connectivity at exactly the same time the major telephone companies are pushing into content? Or are we witnessing the end of the Internet as we know it? Think back to the online world fifteen years ago. There was AOL, there was Compuserve, there was Prodigy, and there was Apple's eWorld. Sure, there were researchers and students posting to Usenet newsgroups and navigating through Gopher sites, but the Internet was a sideshow for individuals and business users. ...the online world of those days was fragmented and small. Every online service was an island. Are we going back to those days? more
