Kyiv Independent Reports on Starlink in Ukraine

"Saint Elon" is a bit much but ... It started with a tweet from Ukraine's Minister of Digital Transformation. The quoted text below is excerpts from How Elon Musk's Starlink satellite internet keeps Ukraine online in The Kyiv Independent. "Among the Ukrainian military, Elon Musk, the richest tech entrepreneur in the U.S., is often half-jokingly referred to as 'Saint Elon.'. The reason is Starlink, Musk's satellite communication system that keeps many Ukrainians, most importantly the military... more

LunaNet – Developing the Internet for the Moon

The NASA-sponsored Artemis program is the first step in the next era of human exploration. Together with a large number of international government and academic partners as well as businesses -- and based on international standards -- NASA will establish a sustainable presence on the Moon. more

How Fast is Starlink Broadband?

We got a recent analysis of Starlink broadband speeds from Ookla, which gathers huge numbers of speed tests from across the country. The U.S. average download speeds on Starlink have improved over the last year, from an average of 65.72 Mbps in 1Q 2021 to 90.55 Mbps in 1Q 2022. But during that same timeframe, upload speeds got worse, dropping from an average of 16.29 Mbps in 1Q 2021 to 10.70 Mbps in 1Q 2022. more

Bringing Broadband to the Arctic

The Arctic region has largely been left out of the broadband arena in the past due to the high cost of building last-mile broadband infrastructure. The primary broadband available in the region has been provided for decades by Iridium Communications, which provided only low-bandwidth connections capable of supporting satellite phones and low-bandwidth monitoring devices. more

Smart Highways or Smart Cars?

It wasn't too many years ago when you couldn't read an article about broadband infrastructure without hearing about the need for smart highway infrastructure that was going to enable self-driving cars. There were various versions of how this would happen, but the predominant concept was that 5G networks along roads would communicate with cars and would enable efficient and safe travel by eliminating driver error by taking the driver out of the equation. 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

SpaceX to Launch Satellites for Competitor OneWeb

On March 2, Russia covered the US flag on the Roscosmos Space Agency rocket that was scheduled to launch 36 OneWeb broadband satellites on March 5. The Russians made two obviously untenable demands -- that OneWeb guarantee that the satellites would not be used for military purposes and the United Kingdom government remove its investment in the company. OneWeb declined, and the satellites were removed from the rocket. more

Starlink’s zoomready Rating Is Going Down

zoomready is open-source shareware I wrote to measure the suitability of an internet connection for teleconferencing. As you can see above, Starlink had an average zoomready rating of 2.66 out of a possible 3.0 over the four measured days. The problem is NOT bandwidth, which has fluctuated but stayed above the minimums needed for good teleconferencing. The problems are failures (most of them short), latency, and jitter. more

Why Did Russia Test an Anti-Satellite Missile and Why Doesn’t China Condemn the Test?

On November 15th, Russia used an anti-satellite missile to destroy COSMOS 1408, a defunct spy satellite. The explosion quickly created over 1,500 pieces of trackable debris and will likely generate hundreds of thousands of smaller pieces. As a precautionary measure, the astronauts on the International Space Station, two of whom are Russians, took shelter in escape shuttles during two orbits. The anti-satellite test was widely criticized, but the Russian defense ministry released a statement saying... more

Potential Impacts of Large-Scale Metaverses on Internet Governance: Bandwidth

Neal Stephenson’s foundational cyberpunk novel Snow Crash brought to the public the concept of a metaverse, a virtual reality in which people interact using avatars in a manufactured ecosystem, eschewing the limitations of human existence. More recently, Ready Player One capitalized on that idea and brought it back to prominence with a bestselling novel and subsequent film adaptation. Amid rebranding efforts and seeking a new way forward, Mark Zuckerberg has made it Facebook’s (now Meta Platforms) priority to build a platform that could enable the metaverse to become a mainstream technology with the sort of reach that their social networks and WhatsApp have. 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

5G for Cars – an Idea That Won’t Die

An industry group calling itself 5G Americas has published a whitepaper that touts the advantages of a smart auto grid powered by 5G and the C-V2X technology. This technology is the car connectivity standard that much of the industry has gelled around, replacing the older DSRC standard. Over a decade ago, the FCC became so enamored over the idea of self-driving cars that the agency dedicated the 5.9 GHz spectrum band for the sole use of smart cars. more

Starlink Beta vs. Fiber

Last year we had terrible DSL from Consolidated Communications and much better, although not always consistent, service from wireless ISP GlobalNet. I signed up for fiber service from Stowe Cable for installation this year and also was accepted early as a Beta tester for Starlink. Now we have both Starlink and fiber and can compare the two. I was very happy to cancel my Consolidated service but felt bad about canceling GlobalNet, which was essential to me for many years. Most of the time, there are only two of us in the house. 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

A Simulation of the SpaceX, Amazon, Telesat and OneWeb Broadband Satellite Constellations

Over two years ago, an MIT research group ran a simulation of the low-Earth orbit broadband constellations of OneWeb, SpaceX, and Telesat, and last January they repeated the simulation updating with revised constellation characteristics and adding Amazon's Project Kuiper. They ran the new simulation twice, once using the planned initial deployments of each constellation and a second time using the configuration shown. more
