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
The American Medical Association fully supports telehealth. The group now has gathered enough evidence of the effectiveness of telehealth and touts the advantages of telehealth to its member physicians. There are still a few ongoing issues involving compensation, privacy, liability, and of course, rural patients without broadband access. 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 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
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
Ajit Pai recently wrote an article in the National Review where he talks about how his decision as head of the FCC to repeal net neutrality was the right one. He goes on to claim that repealing net neutrality was the driver behind the current boom in building fiber and upgrading other broadband technologies. He contrasts the progress of broadband in the U.S. with Europe and says that the FCC's action is the primary reason we are seeing a fiber boom in the U.S. more
On Friday, 23rd June, Caribbean telecommunications operators (telcos) held a meeting in Miami to fine tune their strategy to force Big Tech companies to contribute financially to regional telecoms network infrastructure. Hosted by the Caribbean Telecommunications Union (CTU), and taking a similar perspective to the "fair share" proposal currently being debated in the European Union, regional network operators are arguing that over-the-top (OTT) service providers are responsible for 67 percent of the total Internet traffic in the Caribbean, but make no contributions or investments toward local delivery networks. more
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
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
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
