Quake Damage in Japan

The 8.9-magnitude earthquake in Japan rocked the northeastern portion of the coast. The quake was the strongest to hit Japan in at least a century, sending a tsunami that flooded northern towns and also reached portions of the United States, including Hawaii. The quake was followed by a 7.1-magnitude aftershock. Impact on Internet connectivity... Japan’s Internet performance seemed to have emerged largely unscathed, but concerns continue for the telecommunications infrastructure as the country struggles to meet power demands in a state-of-emergency. more

CALEA Roundup: 2005-2007

The wrangling around the Communications Assistance to Law Enforcement Act (CALEA) is one of those issues that creeps inexorably forward and is hard to follow unless you're really focusing. So here is a quick, if longish, overview: CALEA is a 1994 statute that requires telephone companies to design their services so that they are easily tappable by law enforcement in need of "call-identifying information." Back in August 2005, following a request from the Dept. of Justice, the Commission moved swiftly to impose CALEA obligations on providers of broadband access services and "interconnected VoIP" services... more

LTE Insufficient from the Start, Boingo IPO Propitious

The trouble with planning way ahead is that the world changes before you execute. The major wireless carriers have been planning their 4^th generation LTE (Long Term Evolution) rollouts for a long time -- that's how they do things. Now, even as Verizon Wireless is doing an aggressive rollout of LTE, it's becoming clear that LTE networks will not be able to slake the data thirst of a world full of smart phones and tablets. Whoops. more

The $100 Billion National Broadband Plan for America

The new Biden Administration in the USA laid out a $100 billion proposal for broadband investment as part of its $2 trillion+ infrastructure plan. Under the proposal, the plan is to provide national broadband coverage. The Administration will use better competition measures, such as price transparency, the use of public utility infrastructure, and subsidies for low-income households to achieve its goals. 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

IPv6 or IPv4? What Will We See in the First Wave of LTE Networks?

All the talk early this year seems to be about LTE deployment to alleviate chronic Apple and other smartphones induced indigestion on the AT&T and other major Mobile Networks swamped by data traffic. The telluric shift albeit the user will not care or should not notice is that when he or she will power on that smartphone or whatever the communicating Swiss Knife will be called, it will request an IP address to complete an IP based call. 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

What is Google Up To?

The astonishing rise and rise of the fortunes of Google has been one of the major features of both social and business life of the early 21st century. In the same way that Microsoft transformed the computer market into a mainstream consumer product through its Windows and Office software products some 20 years ago, Google has had a similar transformative effect upon its environment. more

New Innovations in Free Space Optics

I read an article on the Finley Engineering blog that talks about new research with free-space optics. For those not familiar with the term, this means communication gear that communicates directly using light without any wires. The article talks about a Chinese team of scientists who have used light to transmit ultrahigh-definition video signals between high-rise buildings. more

Trump’s Assault on 5G Standards Bodies

Over the past 30 months, since Trump was installed in the White House, he has systematically abrogated US treaty responsibilities and diminished the nation's engagement in international collaborative activities. More recently, his gambits have expanded to market entry, chip component, and software restrictions on Chinese telecommunication equipment vendors, especially Huawei. more

Download Speeds of GSM and 3GSM Networks

ARCchart is selling a new report entitled Mobile Broadband Performance of Carrier Networks. I can't personally justify the purchase, but I notice this wonderful graph in their sample. ARCchart gave mobile users free speed test applications... more

Are the LEOs Going to Disrupt the Telco Market?

We are getting closer to using alternative broadband solutions offered by international companies. Local telecommunication entities will, in this respect, be relegated to resellers. The reality of accessing low Earth-orbiting satellite (LEO) services is now clearly on the horizon. Most of the telcos and governments are not prepared for the potential shock this might cause to the structure of local telecommunications markets. more

Multi-Orbit Broadband Internet Service

Three satellite companies, SES, Telesat, and Hughes, are working toward integrated, multi-orbit broadband Internet service and Eutelsat may join them... It is too soon for these companies to be offering integrated multi-orbit services, but they have begun testing and demonstrating switching and antenna technology. more

America Will Not Win the Global Race to 5G

Several weeks ago, the White House published a document asserting that "America Will Win the Global Race to 5G." The White House should get over it. This is not about America winning any global race to 5G, but the world working together on fundamentally different, complex, new communication networks and services. There are four important points, however. more

Might CubeSats Provide Broadband Internet Connectivity One Day?

In November, 2016, SpaceX filed a request for approval to launch 4,425 Internet-service satellites using the Ku and Ka frequency bands. The satellites were expected to measure 4 x 1.8 x 1.2 meters. In February, 2018 SpaceX launched two Internet-service test satellites - TinTin A and B - that measured only 1.1 x .7 x .7 meters. Why the size difference? more
