Will Telesat Survive?

In 2017, Telesat, an established Canadian geostationary satellite operator, announced a planned low-Earth orbit Internet service constellation. The plan called for 117 satellites with inter-satellite laser links in a mix of inclined and polar orbits, enabling global coverage. more

What Happened to Quantum Networks?

A few years ago, there were a lot of predictions that we'd see broadband networks converting to quantum technology because of the enhanced security. As happens with many new technologies, quantum computing is advancing at a slower pace than the wild predictions that accompanied the launch of the new technology. more

Unintended Consequences of Satellite Constellations

Astronomy & Astrophysics published a research paper recently that looked at "Unintended Electromagnetic Radiation from Starlink Satellites." The study was done in conjunction with the Low-Frequency Array (LOFAR) telescope in the Netherlands. The LOFAR telescope is a network of over forty radio antennas spread across the Netherlands, Germany, and the rest of Europe. more

Google Bard Fails to Answer Satellite Internet Questions

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

Using 42 GHz Spectrum for Broadband

The U.S. Federal Communications Commission circulated draft rules to govern the lower 42 GHz spectrum (between 42-42.5 GHz). This is within the range of spectrum referred to as millimeter wave spectrum. This is one of the more unusual FCC spectrum deliberations because this spectrum is totally empty -- there is nobody currently authorized by the FCC to use the spectrum band. The FCC is starting this deliberation with a clean slate. more

The Fiber Land Grab

It's becoming clear that we are now deep into a fiber land grab. By that, I mean that companies that overbuild fiber in the United States are moving into markets to build fiber as quickly as possible. The biggest ISPs have publicly discussed their plans for building a lot of fiber in 2023. Following are some of the latest projections for 2023: more

Will Electronically Steered Antennas Replace Parabolic Antennas in Satellite Ground Stations? (ChatGPT-Assisted Version)

In a previous post, I asked whether electronically steered antennas (ESAs) would replace parabolic antennas in satellite ground stations. I read a few articles suggested by others and by Google search, used some common sense, produced a list of advantages of ESAs, and concluded that it was likely they would eventually replace parabolic antennas for many applications. more

The Benefits of Thinner Fiber

Fiber manufacturers are always trying to make it easier to deploy fiber. One of the most interesting trends is the increasing migration from 250-micron fiber to 200-micron fiber. For those not familiar with the metric system, a micron is one-thousands of a millimeter. A 250-micron fiber has a diameter of 0.25 millimeters, while a 200-micron fiber has a diameter of 0.2 millimeters. more

Will Electronically Steered Antennas Replace Parabolic Antennas in Satellite Ground Stations?

Three recent developments make me wonder whether we are on the cusp of a shift in satellite ground station technology from parabolic to electronically steered antennas (ESAs). The U.S. Space Force operates the Satellite Control Network, with 19 parabolic antennas at seven locations around the world. more

Starlink’s New Business Broadband

Starlink has quietly updated its business broadband offerings. The original plan for businesses was $500 per month with a two-terabyte data cap. If a customer exceeded the data cap, the speed reduced to 1 Mbps for the remainder of the month unless a customer bought additional broadband at $1 per gigabyte. Starlink business comes with a premium antenna from HP at a one-time cost of $2,500. more

The Trade War for Undersea Fiber

A recent article by Joe Brock for Reuters describes a new geopolitical battle over undersea fibers. There are about 400 undersea fiber routes that cross oceans and that connect the world with fiber. This is a huge business, and about 95% of all international broadband traffic passes through the undersea fibers. more

China and Taiwan Recognize Starlink’s Military Value

When Russia invaded Ukraine, SpaceX had around 2,000 satellites in orbit. It was clear from the first day of the war that a low-Earth orbit (LEO) constellation of around 2,000 satellites would be a valuable military and civilian asset. The first truckload of Starlink terminals arrived in Ukraine on February 28, 2022, four days after the invasion. By March 19, there were 5,000 terminals in Ukraine and 150,000 active daily users by May 2nd.China and Taiwan have both seen the strategic value of 2,000 Starlink satellites. more

The Problem Of 5G Hype

I'm writing this as the 5G hype cycle reaches a new crescendo. What is most striking is how few of those touting 5G (or "private 5G") is how little technical detail there is beyond saying it is the next generation of cellular protocols. Yes, one can look at volumes of specifications with myriad options and flavors but no sense of 5G as such. That alone should make one suspicious - why does one have to eschew wires to get 5G? more

Return of Net Neutrality: Discussion of European Net Neutrality Proposal Relevant for U.S. Broadband Market

There is an interesting recent discussion in Europe about net neutrality that has relevance to the U.S. broadband market. The European Commission that oversees telecom and broadband has started taking comments on a proposal to force content generators like Netflix to pay fees to ISPs for using the Internet. I've seen this same idea circulating here from time to time, and in fact, this was one of the issues that convinced the FCC first to implement net neutrality. more

Is the Broadband Industry Reaching Maturity?

Craig Moffett, of MoffettNathanson, was recently quoted in FierceTelecom asking if the broadband industry is reaching maturity. Other than in rural areas, where many homes are still hungry for better broadband, the broadband penetration rate in cities is approaching 90%. It's a fair question to ask if there is room for much more growth in the industry. This is a question that has bounced around for the last five years. more
