When SpaceX first announced plans for Starlink, their low-Earth orbit Internet service constellation, they said each satellite would have five inter-satellite laser links (ISLLs) - two links to satellites in the same orbital plane, two to satellites in adjacent orbital planes, and one to a satellite in a crossing plane. They subsequently dropped the crossing link as too difficult and, when they finally began launching satellites, they had no laser links. Last year they tested ISLLs on two satellites.
While 2021 will remain a year with lots of uncertainties, at the same time, we can say that the pandemic has not affected the information and communications technology (ICT) industry in any significant way. Yes, there has been a slowdown, for example, in the sale of smartphones. Shortages in both materials and expertise are slowing fiber deployment, and the recovery over 2021 will be slow and uncertain because of the many lockdowns and travel restrictions.
Starlink is satellite internet access from SpaceX, one of Elon Musk's other companies. If it lives up to its hype, it will cure the problem of broadband availability in rural areas, although affordability will still be an issue. Most satellite-based Internet access sucks (that's a technical term). If based on geostationary satellites (ones you can point a dish at), the distance to the satellite is so great that the round-trip time for data is forever; this problem is called latency.
I periodically take a look at broadband trends into the future. But as I was thinking about how unique 2020 was for everybody, I realized that there were some events during the year that we're going to look back on a decade from now as important to the broadband industry. Interestingly, most of these events were not on anybody's radar at the beginning of the year.
As is normal with a change of administration, there are articles in the press discussing the likely legacy of the outgoing administration. Leading the pack in singing his own praises is former FCC Chairman Ajit Pai, who recently published this document listing a huge list of accomplishments of the FCC under his Chairmanship. Maybe it's just me, but it feels unseemly for a public servant to publish an official self-praise document.
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.
As chance has it, the attempt by NTIA to create a fake Trump Open 5G Security Framework MAGAverse as they headed out the door on 15 January is being followed this week by the global meeting of 3GPP SA3 (Security) to advance the industry's real open 5G security Framework. Designated TSGS3-102e (the 102nd meeting, occurring electronically), it continues the practice of assembling companies, organisations, and agencies from around the world every 8 to 12 weeks to focus on 5G security for current and future releases of 5G infrastructure.
As the saying goes, it's not over until it's over. So, it wasn't surprising that Trump's minions just got one last 5G minefield out the door. On 15 January, his followers at Dept. of Commerce's NTIA published the "National Strategy to Secure 5G Implementation Plan". The 40-page document consists of a fairly standard Washington policy playbook of 18 activities with six annexes that "details how the United States along with like-minded countries will lead global development, deployment, and...
As Trump's horrific Administration of non-stop debacles and self-serving gambits headed toward the exit over the past few weeks, one last regulatory grab after another has been pushed out the door while the toddler-in-chief rants. Sure enough, the last of the 5G debacles just appeared in the Federal Register courtesy of the President's policy instrument, the National Telecommunication and Information Administration (NTIA). It was titled the 5G Challenge Notice of Inquiry.
SpaceX began public beta testing of the Starlink Internet service in the northern US late last October. Since then, they have made many software updates based on the beta experience and have expanded the uninterrupted-coverage area by launching new satellites. By the end of the year, they had begun beta service in southern Canada and sent beta test invitations to a few UK users. The beta-eligibility area is expected to expand from the current 45-53 degree latitude this month or next.
