SpaceX Is First With Inter-Satellite Laser Links in Low-Earth Orbit, but Others Will Follow

When SpaceX first announced plans for Starlink, their low-Earth orbit Internet service constellation, they said each satellite would have five inter-satellite laser links (ISLLs) - two links to satellites in the same orbital plane, two to satellites in adjacent orbital planes, and one to a satellite in a crossing plane. They subsequently dropped the crossing link as too difficult and, when they finally began launching satellites, they had no laser links. Last year they tested ISLLs on two satellites. more

Telesat Begins Testing Low-Earth Orbit Satellite Internet Service

SpaceX and OneWeb get a lot of publicity and have ambitious plans, but Telesat is the first low-Earth orbit (LEO) satellite Internet service provider to begin testing with potential resellers. Last January, Telesat launched a demonstration satellite and it is now ready for testing. Maritime connectivity provider OmniAccess and Australian ISP Optus had committed to testing the system previously and this week they were joined by in-flight entertainment company Global Eagle Entertainment. more

Wireless Net Neutrality

To date, most of the discussion on net neutrality has dealt with the behaviour of conventional wireline ISPs. RCR Wireless News is carrying an opinion piece called "Paying for the bandwidth we consume" by Mark Desautels, VP -- Wireless Internet Development for CTIA -- the trade association for the US wireless industry. His article follows up on reports of Comcast cable moving to discontinue internet access service to so-called "bandwidth hogs"... 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

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

Rent vs. Buy: The Driver of Economics

We the people like to own stuff and not pay rent to use it (BTW, rent includes taxes but that's another story). They the oligarchs like to own the stuff and charge us rent to use it. The rise of a middle class has historically meant the rise of a property-owning class. The underclass pays exorbitant rents. The telecommunications world -- or at least the US part of it -- is a battle of rent vs. buy. Economics says that ownership or rentership is all based on access to capital. Certainly capital is a huge part of the equation -- can you spell "home loan"?; but it's not the whole story... more

Consumer Technology vs. 5G

5G represents a threat to the level playing field and innovation of the Internet. It is the new face of the battle over network neutrality. At its inception in the 19th-century, the talking telegraph (AKA the telephone) was an amazing feat of engineering using analog technology. One could speak into a microphone in one city and be heard in another city. Accomplishing this required a very large investment in technology. The customers were consumers of the service. more

Chinese Space Situational Awareness and Traffic Management Regulations and Procedures

In a recent issue of the Dongfang Hour Newsletter, Blaine Curcio pointed out that China's powerful State Administration of Science, Technology, and Industry for National Defence (SASTIND) had published a notice intended to promote the orderly development of microsatellites and strengthen safety management. The notice defines microsatellites as being below 1,000 kilograms, which would include those making up China's planned GwoWang/SatNet broadband constellation. more

SpaceX’s Rural Development Project in India

Sanjay Bhargava, Starlink Country Director for India at SpaceX (source)SpaceX Starlink is moving quickly in India. Last April, they said they would be offering service in 2022 and began accepting pre-orders. In July, SpaceX committed to manufacturing antenna systems and terminals in India and, at the end of September, Sanjay Bhargava, who had been with Elon Musk at Paypal, was selected to head Starlink in India. In the last week or two, they set up a wholly-owned subsidiary that will apply for licenses, seek Indian distribution partners, and attempt to sell 200,000 units - 80% in rural districts - in 2022. more

Japan Fueling China’s Leap to 5G, but for How Long?

As the U.S. is making it tough for American companies to help China roll out super-fast cellular networks, Japan, a U.S. ally, is fueling China with parts needed to blanket the nation with 5G cellular service. more

SpaceX Starlink Is Coming to Low-Income Nations

Beta testers in the US and Canada paid $500 for a terminal and are paying $99 per month for the service. The beta tests began in high-income countries, but SpaceX is beginning to roll Starlink out and will include low-income nations, for example, India. Last September, SpaceX responded to a request for consultation on a roadmap to promote broadband connectivity and enhanced broadband speed from TRAI, the Telecommunications Regulatory Authority of India. more

Did Google’s Infrastructure Coup Work?

There is no doubt that the Google fibre rollout in Kansas City has been a success. Take-up rates are as high as 75%. However, when it was first announced in 2010, we stated that the real reason behind Google's entry into this market was to prove that FttH can be cost-effective and can generate a profitable return -- in the hope that the sluggish telcos would become more active in the rollout of FttH networks. Yet, Google is proving that this indeed can be done, the telcos remain sluggish in deploying FttH. more

A Closer Look at Apple and Location-Tracking

There's been a lot of media attention to a report that iPhones track your movements. It's even reached the U.S. Senate. I'm underwhelmed. I think that the threat is overhyped. What is happening is that these devices create a hidden file with your location... more

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

The Rising Technical Challenges of Networking at Home

For me, one of the more interesting sessions at the recent IETF 81 meeting in July was the first meeting of the recently established Homenet Working Group. What's so interesting about networking the home? Well, if you regard challenges as "interesting", then just about everything is interesting when you look at networking in the home! more
