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
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
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
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
Telstra might regret having signed a commercial deal with London-based OneWeb as this company has now become a pawn in the war between Russia and Ukraine. Telstra agreed to host two OneWeb gateway Earth stations in Australia, one in the west and one in the north, which would also cover the APAC region, with a third Earth station currently under discussion for the east coast. more
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
I’ve lately been looking at broadband policies that have shaped broadband, and I don’t think there has been any more disastrous FCC policy than the one that defines broadband by speed. This one policy has led to a misallocation of funding and getting broadband to communities that need it. The FCC established the definition of broadband as 25/3 Mbps in 2015, and before then, the definition of broadband was 4/1 Mbps, set a decade earlier. The FCC defines broadband to meet a legal requirement established by Congress and codified in Section 706 of the FCC governing rules. more
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
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
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
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
Starlink recently launched a new webpage that advertises the future ability to deliver text, voice, and data to 4G cell phones via satellite. The texting service is supposed to be available in 2024, with voice and data coming in 2025. The service will require a user to have a view of the open sky. more
A recent invitation to participate in a webinar to discuss ICANN's Role in Satellite Internet Governance as an enabler of UN Sustainable Development Goal (SDG) 9 prompted me to consider this issue. As a legal scholar with expertise in telecommunications infrastructure, I had much to say and discuss about the new mega-constellation phenomenon and its potential role in achieving SDG9, which, for me, is a multifaceted and fascinating subject. more
In an earlier post, I asked whether electronically steered antennas (ESAs) would replace parabolic antennas in satellite ground stations. I did some research and concluded that it is likely that they will. Next, I discussed the same question with ChatGPT and, while it made several false statements, it made a relevant point that I had overlooked. The relevant addition was positive, but the errors were troublesome, so I decided to try ChatGPT's competitor Google Bard. more
The FCC voted recently to implement consumer broadband labels. This was required by section 60504 of the Infrastructure Investment and Jobs Act. The new rules will become effective after the Office of Management, and Budget approves the new rules and after the final notice is published in the federal register. ISPs will then generally have six months to implement the labels. The labels look a lot like the nutrition labels that accompany food. more
