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

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

Verizon OPEN Wireless

Very surprising and welcome announcement from Verizon Wireless yesterday announcing that "it will provide customers the option to use, on its nationwide wireless network, wireless devices, software and applications not offered by the company. Verizon Wireless plans to have this new choice available to customers throughout the country by the end of 2008..." And Verizon Wireless is right to open up. There's plenty of room to be cynical about this; after all, Verizon Wireless is trying to STOP the FCC from putting an openness requirement on the 700Mhz spectrum to be auctioned... 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

SpaceX Satellite Internet Project Status Update

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

What to Expect From SpaceX Starlink Broadband Service Next Year and Beyond

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

Will Low-Earth Orbit Satellite Internet Service Providers Succeed?

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

Government of India Gives the Go-Ahead for 5G Technology and Spectrum Trials, Avoids Chinese Firms

The Department of Telecommunications (DoT), Government of India, approved permissions today to Telecom Service Providers (TSPs) for conducting trials for use and applications of 5G technology. more

The Great Internet Transformation? A First Stab

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

Another Wrong-Headed WSJ Editorial

Those wacky editorial writers at the Wall Street Journal just cannot seem to get the facts straight about network neutrality and what the FCC has done or can do on this matter. In the July 30, 2008 edition (Review and Outlook A14), the Journal vilifies FCC Chairman Kevin Martin for starting along the slippery slope of regulating Internet content. The Journal writers just seem to love hyperbole, and are not beyond ignoring the facts when they do not support a party line. Here are a few examples from the editorial... more

700 MHz Update: Will VZ Comply with the Rules?

Last Friday (HT: IPDemocracy), Google filed a petition [PDF] asking that the Commission ensure that Verizon understands what those "open platform" requirements for the C Block really mean. Verizon has taken the position in the past that its own devices won't be subject to the "open applications" and "open handsets" requirements of the C Block rules, and Google says it is concerned that Verizon doesn't plan to follow those requirements in the future. This is big. Here's the background... more

HTTPS Web Hijacking Goes From Theory to Practice

I've been privately talking about the theoretical dangers of HTTPS hacking with the developers of a major web browser since 2006 and earlier last month, I published my warnings about HTTPS web hacking along with a proposed solution. A week later, Google partially implemented some of my recommendations in an early Alpha version of their Chrome 2.0 browser... This week at the Black Hat security conference in Washington DC, Moxie Marlinspike released a tool called SSL Strip... more

Let’s Not Forget About Solar Flares

As the world becomes more and more reliant on electronics, it's worth a periodic reminder that a large solar flare could knock out much of the electronics on earth. Such an event would be devastating to the Internet, satellite broadband, and the many electronics we use in daily life. A solar flare is the result of periodic ejections of matter from the sun into space. Scientists still aren't entirely sure what causes solar flares, but they know that it's somehow related to shifts in the sun's magnetic field. more

The Future of the Internet Economy: Chapter 2

The OECD held a "high-level" meeting in June 2011 that was intended to build upon the OECD Ministerial on The Future of the Internet Economy held in Seoul, Korea in June 2008. I was invited to attend this meeting as part of the delegation from the Internet Technical Advisory Committee (ITAC), and here I'd like to share my impressions of this meeting. This 2 day meeting, "The Internet Economy: Generating Innovation and Growth", had the objective of exploring a number of current issues in the public policy space... more

Would the Real Network Neutrality Please Stand Up?

I'm sure this is something that's been raked over before, but I don't see a common understanding of what 'Net Neutrality' actually is. Despite many of the Internetorati demanding it by law. There appear to be several different camps, which you could paint as "bottom of IP", "middle" and "top". The bottomistas would see enforced Internet Protocol itself as a premature optimisation and violation of the end-to-end principle. Unhappy that you only get IPv4 or IPv6? Still grumpy that you only have IPv4 and not even IPv6? Really miserable that your VoIP packets are staggering under the poisonous load of IPv6 headers? You're a bottomista. more
