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

A Cool Simulation of SpaceX’s Revised Satellite Broadband Plan

On November 15, the FCC approved a revision to the plan for Starlink, SpaceX's forthcoming broadband satellite service. The new plan reduces the number of satellites from 4,525 to 4,409 and lowers the altitude of the phase-1 satellites from 1,100 to 550 km. Mark Handley, a professor at University College London, has created videos based on simulations he ran of both the original and revised phase 1 plans. more

Starlink Has Begun Delivering Promised Latency Cuts

In his January 12 SpaceX update, Elon Musk said the biggest goal for Starlink from a technical standpoint is to get the mean latency below 20 ms. He expanded by saying that given the speed of light, 8 ms is the absolute minimum latency for a satellite at 550 km. He believes they can optimize terrestrial and inter-satellite links, and minimize queueing delays and dropped packets, to recude the the rest of the time to below 10 ms. more

A 5G Community Network Strategy for Cuba (and Other Developing Nations)

In a previous post, I suggested that Cuba might be able to leap over 4G to 5G wireless infrastructure using satellite and terrestrial networks for backhaul. While that would require political and policy change, it would be a good fit with Cuban culture and skills. Before talking about Cuba, let me say a bit about wireless generations. Each mobile technology generation used new technology and enabled new applications. more

Computing Clouds in Orbit – A Possible Roadmap

Last week, I predicted that much of the Internet and most cloud datacenters would launch into space in the next ten years. Today the only part of the Internet in space is a very small amount of "bent-pipe" access: signals which go from a user to a satellite and bounce back down to a ground station which feeds them into the terrestrial internet where all processing is done and all queries answered by internet-connected servers, many of them in cloud data centers. more

OneWeb and Intelsat Sign the First Multi-Orbit Broadband Agreement – More to Come

Last October, I reviewed multi-orbit tests and plans of several low Earth orbit (LEO), medium Earth orbit (MEO), and Geostationary (GEO) broadband satellite companies and quoted Neil Masterson, CEO of LEO operator OneWeb as saying, "Interoperability with GEO satellites must happen - it's common sense ... Customers don't care whether it's a LEO satellite or a GEO satellite - all they want is connectivity." more

Low-Earth Orbit (LEO) Satellite Internet Service Developments for 2020

I posted reviews of important LEO-satellite Internet service developments during 2017, 2018 and 2019. I've updated those posts during the years and have 18 new posts for 2020. In 2020 we saw increased effort from China, OneWeb's bankruptcy and restructuring with new ownership and prospects, Amazon investng in space-related infrastructure, Telesat making steady progress, SpaceX making rapid progress and satellite and debris tracking and collision-avoidsnce service startups. The following are brief summaries of and links to the 2020 posts. more

The Fight Over 12 GHz Spectrum

For an agency that has tried to wash its hands from regulating broadband, the FCC finds itself again trying to decide an issue that is all about broadband. There is a heavyweight battle going on at the FCC over how to use the 12 GHz spectrum, and while this may seem like a spectrum issue, it's all about broadband. 12 GHz spectrum is key to several broadband technologies. First, this is the spectrum that is best suited for transmitting data between the earth and satellite constellations. more

Researchers Expose Privacy Risks in Apple and Starlink’s Geo-Location Data, Uncovering Military and Civilian Tracking

Researchers from the University of Maryland have revealed significant privacy and security concerns related to the way Apple and Starlink geo-locate devices. Their study found that Apple's Wi-Fi Positioning System (WPS) collects and publicly shares precise locations of Wi-Fi access points. more

The Unprecedented Role of the Internet in the War in Ukraine

The impact of the Internet in the Russia-Ukraine war is unprecedented in speed and scope. The most visible example of this has been President Zelenskyy's use of social media and teleconferencing in his roles as Commander in Chief of the armed forces, a global diplomat, and a leader of the Ukrainian people. more

It’s the Latency, FCC

Section 706 of the Telecommunications Act of 1996 orders the FCC to "encourage the deployment on a reasonable and timely basis of advanced telecommunications capability to all Americans." On October 25, The FCC issued a notice of inquiry (NOI) into how well we are doing and invited comments. The NOI points out that COVID and the concomitant increase in the use of interactive applications has "made it clear that broadband is no longer a luxury... 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

Telesat Update – Proposal for a Larger Constellation, Canadian and DARPA Contracts, IPO and More

I've discussed Telesat's LEO broadband project in earlier posts, but the project has progressed, so an update is needed. The original plan was to launch 117 satellites but that has changed. The phase 1 constellation will now have 298 satellites and the second phase will add 1,373 for a total of 1,671. The revised plan has been submitted to the FCC, and they expect it to be approved next year. more

Aalyria, a Space Internet Startup With Nearly a Decade’s Worth of Intellectual Property From Alphabet

Aalyria, a new space Internet company, just burst out of stealth mode. It is based on work done on Alphabet's "moonshot" Project Loon and Alphabet transferred almost a decade's worth of technology IP, patents, office space, and other assets to Aalyria in return for an equity stake in the company. Spacetime is Aalyria's intelligent network orchestration technology, and Tightbeam is its advanced atmospheric laser communications technology. more

Starlink to Go - Stress Tested in Ukraine and Now Available to You

Russians have targeted Ukrainian electricity and communication infrastructure. In some areas, there may not be any utility poles left standing, and underground conduits may have been bombed to oblivion. Starlink has been an important tool for these brave people to coordinate their resistance to Putin's brutal invasion. Satellite communication doesn't require any middle-mile infrastructure. more
