The Role of the BFR in SpaceX’s Satellite Internet Service

SpaceX started with their Falcon 1 booster followed by several versions of the Falcon 9. The Falcon Heavy will fly later this year, and the rocket that will take the first person to Mars is called, for now, the Big F*ing Rocket or BFR. The 150-ton BFR payload will be ten times that of the Falcon 9. It will have an extra landing-guidance engine for reliable reusability and SpaceX also expects to be able to soft-land and reuse the second-stage payload rocket as well as its protective nose cone, substantially reducing cost per launch. 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

Group of Engineers Have Created a Way to Detect Dangerous Objects in Baggage Using Public Wifi

Report describes a technique with which public wifi can be used to identify in-baggage dangerous objects in public spaces that don't typically have affordable screening options. more

Western LEO Satellite Internet Update: OneWeb, Telesat, Amazon Project Kuiper and IRIS²

While Starlink dominates the low-Earth orbit internet race, rivals like OneWeb, Telesat, Amazon's Project Kuiper, and Europe's IRIS² are slowly building capacity, buoyed by geopolitical necessity, state support, and commercial partnerships. more

Emerging Markets Tech Watch 2012

2011 has been a significant year for the technology sector globally. Information technology is touching more people in more ways than ever before. Developed markets will be considering a 2012 in which business innovation, competitiveness, and service differentiation are built on ubiquitous broadband, cloud computing, smarter mobile computing, and an increasing plethora of Internet-connected devices. By contrast, securing the technology future for developing markets demands that attention be placed on more fundamental issues. more

Can SpaceX Launch 30,000 Second-Generation Starlink Satellites? Maybe

The bottom line is that success is not guaranteed, but neither is failure -- there is a non-zero probability of success. On May 26th, SpaceX applied for permission to launch 30,000 "second-generation" Starlink broadband Internet satellites. (Note that the software on Starlink satellites is updated about once a week). The application narrative states that the second-generation satellites will be configured... more

Goo Goo Goggles: 700MHz Spectrum Auction and the U.S. Taxpayers

Scott Cleland claims the open access rules on 700MHz spectrum triggered by Google's bid fleeced the US taxpayer by $7bn. I don't buy it, even as a signed-up fully-paid network neutrality opponent. Firstly, the numbers ignore economics. If the C block was encumbered, that would raise the prices of the A and B blocks. So you need to take a much smaller differential as to the cost of the encumbrance. more

Latecomer Amazon Will Be a Formidable Satellite ISP Competitor

In spite of being a latecomer to the race to deploy a constellation of low-Earth orbit (LEO) broadband Internet satellites, Amazon's Project Kuiper will be a formidable competitor. SpaceX, OneWeb and Telesat already have test satellites in orbit, but Amazon has several strategic advantages. For a start, each of the LEO broadband competitors plans to end the digital divide by providing global connectivity to end-users and small organizations in underserved areas... more

An Attack on WiFi Spectrum

A little over a year ago, the FCC approved the use of 1,200 MHz of spectrum in the 6 GHz band for public use -- for new WiFi. WiFi is already the most successful deployment of spectrum ever. A year ago, Cisco predicted that by 2022 that WiFi will be carrying more than 50% of global IP traffic. These are amazing statistics when you consider that WiFi has been limited to using 70 MHz of spectrum in the 2.4 GHz spectrum band and 500 MHz in the 5 GHz spectrum band. more

To 5.5G and Beyond

I recently saw an article in FierceWireless that reports that Huawei thinks we are going to need an intermediate step between 5G and 6G, something like 5.5G. To me, this raises the more immediate question about why we are not talking about the steps between 4G and 5G? The wireless industry used to tell the truth about cellular technology. You don't need to take my word for it... more

Global 5G Connections Expected to Reach 1.9 Billion by End of 2023 and 5.9 Billion by End of 2027

The fifth generation of wireless cellular networks, "5G", has seen remarkable growth in the last year, reports industry trade organization 5G Americas. more

SpaceX Starlink in Ukraine – a Week Later

Last week I wrote about the arrival of a truckload of SpaceX Starlink terminals in Ukraine and their potential value to government and resistance leaders. A lot has happened in the ensuing week - this is an update. Last week, using Mike Puchol's Starlink tracking service, I found that users in Kyiv would have 100 percent uptime with connections through as many as nine satellites to ground stations in Turkey, Poland, and Lithuania. more

Why Farmers Are Using Wifi to Grow Your Grapes

Recently, California farmer Craig Thompson got a pretty nifty upgrade for his irrigation: a broadband-connected Hydrawise control system that would automatically manage and monitor the irrigation of his olive and grape fields and collect data to alert him if there was a problem. He woke up the next morning to fields he could have assumed were appropriately hydrated, but the Hydrawise system quickly proved its worth when he looked at the data coming out of it. more

A Transport Protocol’s Perspective on Optimizing Starlink Performance

Digital communications systems always represent a collection of design trade-offs. Maximizing one characteristic of a system may impair others, and various communications services may choose to optimize different performance parameters based on the intersection of these design decisions with the physical characteristics of the communications medium. 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
