Scientists led by a team at Karlsruhe Institute of Technology (KIT) have broken a record for data transmission, sending data at 26Tb/s on a single laser beam over 50km. To put this into context, the researchers suggest that this is the equivalent of transferring the contents of 700 DVDs per second, or the entire collection of the Library of Congress in ten seconds.

This sounds extreme, but Comcast continues to push the boundaries in separation of its broadband service with its cable service. It is walking a thin line between being a broadband provider, offering fast Internet access to millions of subscribers, and treating its Xfinity Xbox 360 App as a priority over customers not having its cable service. Saying the Xbox 360 is just another set-top-box for its own customers is just a complex way of undermining Net Neutrality rules as defined by the FCC upon the companies purchase of NBCU. more
Starlink is satellite internet access from SpaceX, one of Elon Musk's other companies. If it lives up to its hype, it will cure the problem of broadband availability in rural areas, although affordability will still be an issue. Most satellite-based Internet access sucks (that's a technical term). If based on geostationary satellites (ones you can point a dish at), the distance to the satellite is so great that the round-trip time for data is forever; this problem is called latency. more
Let's say that providing communications infrastructure is an inherent function of a state. Most people think of the internet as a telephone system, and most people think the telephone companies aren't supposed to choose which calls will go through based on their content. People think that because they think internet access, like telephone access, is a utility -- like electricity conduit, water pipes, etc. -- that has something to do with the government, and the government isn't supposed to discriminate. more
It was just last year that those of us raising alarms about the massive half-decade market failure in the United States to adequately provision broadband services were facing a misinformation campaign that raw numbers mattered more than percentage rankings. According to this argument, the U.S. broadband market was sound because we had more broadband lines than anyone else. The misinformation brigade got so much attention that public interest groups had to issue reports systematically refuting the PR are marketing hype. more
I write a lot about the U.S. Federal Communications Commission (FCC), but I imagine a lot of folks don't realize the many functions the agency handles. Like any regulatory agency, the FCC staff and Commissioners have been tasked by Congress with a wide range of responsibilities. The public gets to hear from the FCC formally once each month ... more
It looks as if the big boys like AT&T, Verizon and Comcast are passing on the stimulus money. The official reason is that they don't need it, that they enough cash on hand to build out their networks on their own. Fair enough. Perhaps the funding should be reserved for those more in need, those that just need a boost to fund a new business model or expand service. But there are probably other reasons. more
Between December 10th and 11th 2015, the China Future Network Development and Innovation Forum, jointly hosted by the Chinese Academy of Engineering and the Nanjing Municipal Government, is scheduled to be held in Nanjing, Jiangsu, China. The forum will be jointly organized by Jiangsu Future Networks Innovation Institute and Beijing Internet Institute, with the theme of "Building future network test facilities and promoting network development & innovation", and it will invite nearly a hundred industrial experts at home and abroad, to establish a platform marked by security, innovation, openness, cooperation where the policy, industry, academics, and application are integrated. more
Multiple subsea cable breaks have significantly disrupted internet connectivity across South Africa, affecting a wide range of internet and cloud service providers and leaving thousands of users disconnected. more
A group of 24 CEO's and Internet company founders submitted a letter today to the Federal Communications Commission in support of the Net Neutrality initiative. Also last week, in a similar letter, Vinton Cerf, Stephen Crocker and other Internet pioneers spoke out on Net Neutrality supporting FCC's recent open Internet initiative. more
Network Neutrality is a hot topic in the US. The FCC held hearings in my neighborhood recently (while I was in Asia). Now I see Professor Susan Crawford will be testifying next Tuesday at a House Judiciary Committee hearing on "Net Neutrality and the First Amendment." I look forward to her remarks, but I worry that the whole discussion will be focused on "IP Pipes," that is connectivity at network layer 3. This distracts us from the fundamental problem... more
This is a topic that we have discussed on several occasions over the last decade, but it now seems as though things are slowly moving forward. A new company, Intabank, has set up a service whereby its enterprise customers can pool bandwidth that the intermediate company can then use to sell to other customers; enabling organisations to monetise their network connectivity assets. more
I think the concept that I have to explain the most as a consultant is oversubscription, which is how ISPs share bandwidth between customers in a network. Most broadband technologies distribute bandwidth to customers in nodes. ISPs using passive optical networks, cable DOCSIS systems, fixed wireless technology, and DSL all distribute bandwidth to a neighborhood device of some sort that then distributes the bandwidth to all of the customers in that neighborhood node. more
The Telecommunications Policy Review Panel report [Canada] was released yesterday and while the immediate reaction will no doubt focus on the recommendations for a market-oriented approach with significant changes to the CRTC, I would call attention to three other recommendations gleaned from reading the executive summary (the full document is nearly 400 pages). more
Apparently, we consumers in the USA don't need to have broadband speeds of 25 Mbps or higher. And we certainly don't need upload speeds greater than 3 Mbps! At least, that's according to comments filed to the US Federal Communications Committee (FCC) by the National Cable & Telecommunications Assocation (NCTA) in response to the FCC's proposal to raise the definition of "broadband" from 4 Mbps downstream and 1 Mbps upstream to 25 Mbps down and 3 Mbps up. more
