Broadband

Our New Infrastructure

Today, there is demand for more broadband as people realize the importance of being connected to the Internet, whether to access websites, stream entertainment, attend school, attend family events, work remotely, and so much more. This demand has been driven by the success of today's Internet. It is now time to recognize the Internet as infrastructure. The Internet's best-effort approach has allowed us to share the abundant capacity latent in the existing facilities by converting all traffic into packets. more

Is the Defense Innovation Unit’s Hybrid Space Architecture the “ARPANET” of Space and Will It Run on Aalyria Spacetime?

The goal of the Defense Innovation Unit (DIU) of the Department of Defense is to strengthen our national security by accelerating the adoption of commercial technology throughout the military and strengthening our allied and national security innovation bases. Space is one of its areas of focus and two of the space "lines of effort" are multi-orbit operations and logistics and hardware-to-software transformation modernization. more

Defining Broadband

The FCC is seeking public comments to help create a better definition of "broadband". The effort is in relation to its development of a National Broadband Plan by February 2010 as part of the American Recovery and Reinvestment Act. Accurately noting that "broadband can be defined in myriad ways" and "tends to center on download and upload throughput," the FCC seeks a more robust definition. The definition will be part of the governance over those receiving funding for broadband development as part of the Recovery Act. This could get interesting. more

The Other Vote on November 4th

The vote that Federal Communications Commissioners are planning for November 4 is not as important as the voting we'll do on that day, but it does matter a lot to the future of the United States. Unless the forces opposed to progress manage to postpone FCC action (which they are trying very hard to do), the FCC could decide to set the stage for another generation of innovative products with which the US will strengthen its competitive position in global markets... more

Amazon’s Orbiting Infrastructure

I have been following satellite Internet service since the 1990s, but I was surprised when I learned last week that Amazon had filed an application for a 3,236-satellite constellation of low-earth orbit Internet service satellites - Project Kuiper. I shouldn't have been surprised - Amazon was an infrastructure company from the start. In his first post-IPO letter to shareholders in 1997, Jeff Bezos pointed out that their distribution center capacity grew from 50,000 to 285,000 square feet and said their goal remained... more

Protests in Iraq Lead to a Two-Day Internet Shutdown by the Government

Widespread protests in Iraq against the government have lead to a state of emergency where the government has ordered disconnection of the fiber backbone of Iraq that carries traffic for most of the country. more

What’s the Right Definition of Upload Speed?

I read a blog on the WISPA website written by Mark Radabaugh that suggests that the best policy for broadband speeds would be met by asymmetrical architecture (meaning that upload speeds don't need to be as fast as download speeds). I can buy that argument to some extent because there is no doubt that most homes download far more data than we upload. But then the blog loses me when Mr. Radabaugh suggests that an adequate definition of speed might be 50/5 Mbps or 100/10 Mbps. more

Facebook Enters Wholesale Fiber Business, Plans to Sell Unused Capacity on New Fiber Routes

Facebooks says it intends to allow third parties - including local and regional providers - to purchase excess capacity on its fiber. more

Why Understanding Bandwidth is Essential for Improving Subscriber QoE

Measuring and managing subscriber bandwidth can be an easy and cost-efficient way to improve subscriber quality of experience (QoE). In a HFC cable network, bandwidth is shared among users in the same fiber-node. Even though improvements in DOCSIS technology has allowed a substantial increase of bandwidth availability per fiber-node, a few heavy users - as well as new 4K video content - can quickly kill recently-made network investments and leave subscribers with an impression that they are not receiving the quality they deserve. more

Why Telcos Don’t Get Networks

I've posted to SSRN my paper on why most telecom companies, even though they operate networks, don't appreciate the fundamental business dynamics of network structures. This will be a chapter in a book Wharton is publishing on network-based strategies and competencies. In the paper, I describe two views on telecom and Internet infrastructure... more

Starlink Service Is Great on (Some) Cruise Ships

I recently used Starlink on a cruise along the coast of Northwest Africa, and I'll summarize my experience below, but first let me explain why I put some in the title of this post. I posted the following request on the Reddit Cruise group: "What has been your experience of Starlink Internet service on Seabourn or other cruise lines? How was latency? Do video chats work smoothly? Games? etc." more

Fiber Infrastructure in China Has Grown Nine Times Faster Than in the U.S. Since 2013

While developed and developing countries are fully aware of the importance of robust Internet infrastructure in the digital age, none have the same level of ambition that has fueled China's aggressive rollout strategy over the past seven years. more

Telling the Truth About 5G

I still run across articles that extol the supposed wonders of 5G. The most recent, published in Gizmodo asks "How 5G Could Replace Your Home Broadband Connection". I was surprised to see an article like this in a tech-oriented site because the article gets most of the facts wrong about 5G - facts that are not hard to verify. This article talks about 5G having "faster download speeds, faster upload speeds, more bandwidth, and lower latency" than landline broadband. more

North American Broadband Trends

The broadband sector, like the wireless sector, is one of the strongest growth areas of telecommunications. Unlike most OECD countries, where DSL tends to dominate, the majority of subscribers in the US fixed broadband market are cable subscribers. During 2010 the gap continued to widen as the cable companies accounted for 70% of new broadband subscribers compared to the telcos' 30%. Although new broadband networks such as FttH and WiMAX are being widely deployed, broadband competition in each region is still generally limited to one DSL and one cable operator. more

How to Manage Internet Abundance

The Internet has two billion global users, and the developing world is just hitting its growth phase. Mobile data traffic is doubling every year, and soon all four billion mobile phones will access the Net. In 2008, according to a new UC-San Diego study, Americans consumed over 3,600 exabytes of information, or an average of 34 gigabytes per person per day. Microsoft researchers argue in a new book, "The Fourth Paradigm," that an "exaflood" of real-world and experimental data is changing the very nature of science itself. We need completely new strategies, they write, to "capture, curate, and analyze" these unimaginably large waves of information. more
