IPv6 Over Satellite: Pie in the Sky?

I am writing this from the Satellite 2008 conference in Washington, D.C. As I make my way through the exhibits, I see many vendors advertising IP capabilities in their hardware products or network services. But when asked about IPv6 support, the common reply is a not so believable "it is on our roadmap" followed by a somewhat vague delivery date. Although IPv6 development has been slow across the board, it appears to be moving even more slowly in the satellite world... more

Electronically Steerable, Flat-Panel Antennas for Satellite and Terrestrial Connectivity

What will the cost and capability of these antennas be in ten or twenty years? What would be the applications and implications of ubiquitous wireless networks? You might have some short-term guesses, like smart cities, but farther out it's science fiction -- Gaia, the Noosphere, 1984? ... Three companies, OneWeb, SpaceX and Telesat, plan to provide global, low-latency broadband Internet service using constellations of low-Earth orbit (LEO) satellites. more

The Internet’s Gilded Age

The rise of the Internet has heralded rapid changes in our society. The opportunities presented by a capable and ubiquitous communications system and a global transportation network have taken some corporations from the multinational to the status of truly global mega-corporation. Good examples of these new corporations include Google, Apple, Amazon, Microsoft and Facebook. There are a handful of large-scale winners in this space and many losers. But this is not the first time we've witnessed a period of rapid technological and social change. more

Beavers Chewing Through Fiber Cable Cause Hundreds Lose Internet in a Canadian Remote Community

Internet service was down for nearly 900 customers in Tumbler Ridge, British Columbia, over the weekend after beavers chewed through a crucial fiber cable, resulting in "extensive" damage. According to a statement from the area's telecom provider, Telus, the outage also affected some cable TV customers and caused disruptions to local cell phone services. more

The Future of Home Networking: A Problem Statement

I'm a network engineer, and like many engineers I often gravitate to the big projects; large networks with problems of scale and complexity in my case. However, I also consider myself a student of Occam's razor and often quote Antoine de Saint-Exupéry: "perfection is reached not when there is nothing left to add, but when there is nothing left to take away." In this spirit of "less is more" I have recently become intrigued by the problems appearing in home networking. more

Polish Presidential Veto Threatens Starlink Continuity in Ukraine

Earlier this week, Poland’s new President, Karol Nawrocki, vetoed amendments to the Act on Assistance to Citizens of Ukraine, provoking debate over critical satellite connectivity. Deputy Prime Minister and Minister of Digital Affairs Krzysztof Gawkowski warned that the veto “de facto switched off Starlink for Ukraine,” potentially disrupting connectivity for hospitals, schools, and government operations. more

FCC Approves White Space for Broadband in Unanimous Vote

The Federal Communications Commission (FCC) today approved, in a 5-0 unanimous vote, the plan to open up unused, unlicensed portions of TV white space spectrum for wireless applications and devices. However, to prevent interference, FCC has also placed some "rigorous certification process" which device offered by a technology company for use on the white spaces will have to go through. more

Freedom of Expression Part 2: Blocking, Filtering and Removing Online Content

The Internet is a catalyst for what has revolutionised and transformed human societies in giving extraordinary access to information that has catapulted development and economic growth. It also comes with threats of exploitation by those who wish to do harm. In Part 1 of these series, we looked at how Twitter banned Graham Linehan for his tweet where we saw that to an extent, it was justifiable under Californian law but that a Judge in the Fiji courts would disagree with. more

FBI Pushing Plans to Force Surveillance Backdoors on Social Networks, VoIP, and Email Providers

Declan McCullagh reporting in CNET: "The FBI is asking Internet companies not to oppose a controversial proposal that would require the firms, including Microsoft, Facebook, Yahoo, and Google, to build in backdoors for government surveillance. In meetings with industry representatives, the White House, and U.S. senators, senior FBI officials argue the dramatic shift in communication from the telephone system to the Internet has made it far more difficult for agents to wiretap Americans suspected of illegal activities..." more

Update on China SatNet’s GuoWang Broadband Constellation – Can They Do It?

In 2020, China applied to operate GuoWang, a constellation of 12,992 low-Earth orbit (LEO) broadband Internet satellites, and in 2021, it became clear that it was intended to become China’s global LEO broadband constellation. Can they do it? Maybe, but it will take a long time. China does not have the capacity to launch 12,992 satellites today. I don’t know the mass of their planned satellites, but GuoWang is informally referred to as China’s answer to Starlink. more

Google Fiber Project: Programming Key to Success

Google has officially rolled out its long-touted Google Fiber Project showcasing what broadband should look and feel like to all users. Yes, it sets the new standard for broadband connections with a 1Gig speedster, over 100 times faster than current broadband offerings in the U.S. Not-withstanding, just speed will not be the determining success factor; the availability of competitive programming will become the deciding judgment in Google's move to tout reasonable costs to bundled broadband. more

Limitations of Carrier Grade NAT, and Some Workarounds

Qtel, the largest carrier in Qatar (and nearly the only Internet provider) appears to connect all their users (~600K) to the Internet through just one or a very few public IPv4 addresses. 82.148.97.69 was their single public address in 2006-2007. How can network address translation (NAT) put all those users through just one IP address? more

SpaceX’s Starlink Internet Service Will Target End Users on Day One

Starting with Teledesic in 1990, would-be Low-Earth Orbit (LEO) satellite constellations have been justified to the FCC, other regulators, and the public as a means of closing the digital divide. Teledesic's goal was "providing affordable access to advanced network connections to all those parts of the world that will never get such advanced capabilities through existing technologies." Today's low-Earth Orbit (LEO) satellite companies make the same claim, but Telesat, OneWeb and Leosat seem to be targeting commercial markets first. more

Chinese LEO Satellite Internet Update: Guowang, Qianfan, and Honghu-3

China has pursued a strategy of competition among government-owned organizations, and it initiated two government-owned constellation projects, Hongyun and Hongyan, in 2018. In April 2020, China's National Development and Reform Commission included "satellite internet" on its "new infrastructures" list, and China applied to the ITU for a new constellation, called GW. more

Paid Peering: Issues and Misunderstandings

Recently I was asked for my opinion on Google paying France Telecom (FT) to deliver traffic into FT's network, i.e. Google paying to peer with FT. I wasn't aware Google pays FT. I don't even know if it's true. But I do know this is a topic fraught with misunderstandings. Also, if there is a "problem" here, the problem is one of competition (or lack thereof) in portions of the French broadband access market. It is not a problem that can be or should be fixed by "network neutrality" regulations or legislation. more
