The Impact of Satellite Broadband

Recently I've had several people ask me about the expected impact of low-orbit satellite broadband. While significant competition from satellites is probably a number of years away, there are several major initiatives like StarLink (Elon Musk), Project Kuiper (Amazon), and OneWeb that have announced plans to launch swarms of satellites to provide broadband. more

Might Satellite Constellations Learn to Avoid Debris?

The European Space Agency (ESA) reported that as of January 2019 there were about 5,000 satellites in space and 1,950 of them are still functioning. Hopefully, those functioning satellites have fuel and thrusters that will enable them to de-orbit and (mostly) burn up in the atmosphere when their useful life is finished. The remaining 3,050 are slowly drifting, along with a lot of debris. The ESA estimates that there have been over 500 break-ups, explosions, collisions, or anomalous events... more

SpaceX Reports Significant Broadband Satellite Progress

SpaceX delayed last Wednesdays Starlink launch due to high winds and on Thursday they decided to do a software update and postpone the launch until next week, but they revealed significant progress in their Starlink mission press release and in tweets by and a media call with Elon Musk. The mission press release said SpaceX has significantly reduced the size and weight of their satellites. more

Satellite Internet Service Progress by SpaceX and Telesat

This has been a busy week in the race to deploy constellations of low-earth orbit (LEO) Internet-service satellites. In their quarterly report, Telesat mentioned progress in two, disparate markets. As I noted earlier, they have signed their first LEO customer - Omniaccess a provider of connectivity to the superyacht market. more

American Households Estimated to Save Over $30 Billion a Year on Broadband With LEO Satellites

Low Earth Orbit (LEO) satellites are still in their infancy, but according to one analysis, the technology could save American households more than $30 billion per year by intensifying broadband competition more

Google and ETECSA Will Agree to Exchange Internet Traffic Without Charge

Google and ETECSA have signed a memorandum of understanding agreeing to negotiate a peering agreement that would allow cost-free data exchange between their networks once an undersea cable physically connects them. Google has worked hard to establish a relationship with ETECSA and the Cuban government. In recent years, Cuba, not the US, has limited the Cuban Internet. This agreement telegraphs a change in Cuban policy. more

SpaceX’s Starlink Internet Service Will Target End Users on Day One

Starting with Teledesic in 1990, would-be Low-Earth Orbit (LEO) satellite constellations have been justified to the FCC, other regulators, and the public as a means of closing the digital divide. Teledesic's goal was "providing affordable access to advanced network connections to all those parts of the world that will never get such advanced capabilities through existing technologies." Today's low-Earth Orbit (LEO) satellite companies make the same claim, but Telesat, OneWeb and Leosat seem to be targeting commercial markets first. more

Low-Earth Orbit (LEO) Satellite Internet Service Developments for 2018

At the end of 2017, I posted a review of important LEO-satellite Internet service developments. I've been updating those posts during the year and have also added the following new posts in 2018. ... SpaceX, OneWeb and Telesat are planning to offer Internet-service from LEO, but O3b is already providing connectivity to relatively large customers like mobile phone companies, government organizations, and cruise ship lines using a constellation of medium-Earth orbit (MEO) satellites.  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

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

SpaceX Authorized by U.S. Federal Communications Commission to Provide Broadband Satellite Services

The U.S. Federal Communications Commission approved an application by Space Exploration Holdings (SpaceX) to provide broadband services using satellite technology in the United States and around the world. more

Cuba’s Mobile-Internet Strategy?

This post is speculative, but I think Cuba may use satellite for 3G backhaul and, when the technologies are ready, leapfrog over 4G to 5G mobile connectivity and next-generation satellite. ETECSA began rolling out 3G connectivity for Cubans about a year ago and a few things have led me to believe they will continue... But, could they provide widespread 3G mobile? Doing so would require more base stations and more backhaul from those base stations to the Intenet. more

Cuban Satellite Connectivity - Today and (Maybe) Tomorrow

In January of 2017, Doug Madory of Dyn Research reported on Cuban traffic, noting that C&W's share had increased. Later in December Madory reported that ETECSA had activated a new internet transit provider, medium-Earth orbit (MEO) satellite-connectivity provider O3b Networks (Other 3 billion), replacing geostationary satellite provider Intelsat. (They have also added Telecom Italia, which, until 2011, owned 11% of ETECSA, but I will save that for another post). more

SpaceX Starlink and Cuba - A Match Made in Low-Earth Orbit?

I've suggested that Cuba could use geostationary-orbit (GSO) satellite Internet service as a stopgap measure until they could afford to leapfrog over today's technology to next-generation infrastructure. They did not pick up on that stopgap suggestion, but how about low-Earth orbit (LEO) satellite Internet service as a next-generation solution? SpaceX, OneWeb, Boeing and others are working on LEO satellite Internet projects. more

Important Developments on Low-Earth Orbit Satellite Internet Service (2017 Review)

The internet is unavailable and/or unaffordable by about 50% of the world's population. The situation is worse in, but not confined to, developing nations where the service is typically sub-standard when it is available.Geostationary satellite connectivity is available globally, but it is slow and expensive because the satellites are high above the Earth. Low-Earth orbit (LEO) satellites can deliver speeds comparable to terrestrial links, but constellations of many satellites would be needed to serve the entire planet. more
