In the move towards enabling mobile devices to use TV white spaces spectrum, Google along with Comsearch, Dell, HP, Microsoft, Motorola, and Neustar today announced the launch of White Spaces Database Group. The creation of this database has been part of FCC's big vote and approval of white spaces for broadband back in November. This is a required measure to ensure devices can locate channels and avoid interference. more
SpaceX on Tuesday disclosed that it has received 500,000 preorders for its Starlink satellite internet service and that it anticipates no technical problems meeting the demand. more
I'm writing this in response to the myriad discussions about how to make sure that the Internet continues to "work" despite P2P or whatever the current threat seems to be. Behind much of the discussion is the presumption that the Internet has a purpose in the sense of making some applications like video games and VoIP work. Yesterday we feared modems, today we fear P2P. more
In his January 12 SpaceX update, Elon Musk said the biggest goal for Starlink from a technical standpoint is to get the mean latency below 20 ms. He expanded by saying that given the speed of light, 8 ms is the absolute minimum latency for a satellite at 550 km. He believes they can optimize terrestrial and inter-satellite links, and minimize queueing delays and dropped packets, to recude the the rest of the time to below 10 ms. more
As industry watchers know, the UN's World Summit on the Information Society (WSIS+20) review marks a pivotal moment that will shape internet governance well into the 2030s and beyond. In response, the team at CIRA has published a new report, emphasizing why the multistakeholder model should not only be protected, but refreshed and reinvigorated for the challenges that lie ahead. more
What would duopoly providers of internet access really like to have? They'd really like to be paid for providing non-commodity services. They'd really like to be rewarded for running the network, top to bottom. "But that's not possible," you say. No provider can tell one packet from another. Providers can only block the ports used by applications they don't like, and that's a clumsy, unwinnable arms race. The applications can always switch to common and useful ports, and no provider wants to alienate its subscriber base. But what if providers could inspect the contents of packets, without using too much computational power, and discriminate among applications? "Naah," you say. "They can't possibly do that."... 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
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
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
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
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
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
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
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
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
