There was a burst of recent press about cellular service provided from satellites. This was probably prompted by the two recent hurricanes that have disabled terrestrial cellular and broadband networks in the southeast. I've seen speculation and discussion on Reddit and other forums where people have been wondering if satellite is the future of cell service and if the ubiquitous giant cell towers will eventually become obsolete.
Ookla recently tackled this question in one of its research articles. Ookla compared the time it takes to load pages for Facebook, Google, and YouTube on cellphones using 4G LTE networks versus 5G networks. Ookla thinks that page load speed is a great way to measure cellphone experience. The time needed to load a web page is directly impacted by latency, which measures the lag between the time a phone requests a website and that website responds.
There are many inconvenient truths about radio spectrum sharing and transceiver interoperability that require full ventilation and resolution. Spectrum users want exclusive access and - news flash - they do not like to share! Campaign events, like the Trump Bulter, PA rally, require short notice, forced cooperation between and among federal, state, and local law enforcement officers, as well as a variety of other government agencies.
Linda Hardesty wrote an interesting article in FierceNetwork that asks the question, "What if, in ten years, young people don't subscribe to fixed broadband at all?" Her story is based on a U.K. research group that predicts that within ten years, there will be a lot of young people who will never have subscribed to a landline broadband product.
I've read several articles coming out of the Mobile World Congress trade show in Barcelona, Spain, and one of the common threads is that there was a lot of talk about 5.5G (or 5G Advanced) - the next iteration of 5G. My first question on reading about this was to ask what new features are being discussed that were not part of the original announced promises of 5G. I went back and read a few of my blogs and other articles that were written when 5G was first announced.
In the February 13th edition of the Wall Street Journal, Professor Thomas W. Hazlett offers a breathless endorsement of market concentration with the T-Mobile acquisition of Sprint, his go-to example. Apparently, mergers and acquisitions benefit consumers because they enhance competition and generate all sorts of positive outcomes that could not possibly have occurred but for the reduction in the number of industry players.
I work with a lot of ISPs that own rural fiber. Some rural network owners have been successful in providing fiber to cell sites near their networks over the last decade. A few sell directly to a cellular carrier, but most of these connections are sold to an intermediate carrier that bundles together cellular connections across a large geographic area.
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.
AT&T and Comcast recently joined forces and joined the 5G Open Innovation Lab. This is a venture that has been funding start-ups and others working in 5G research. Along with looking to improve 5G edge technology, a primary goal of the OAI Lab is to search for killer apps for 5G. The two big companies join the other founding members of the effort, which includes Dell, Intel, Microsoft, Deloitte, and Nokia.
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.
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.
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.
The U.S. Federal Communications Commission (FCC) has seemingly joined forces with the marketing arm of the cellular industry in declaring that the spectrum between 7-16 GHz is now considered to be 6G. Chairman Jessica Rosenworcel recently announced that the agency would soon begin looking at the uses for this spectrum for mobile broadband.
The Australian Signals Directorate (ASD) has issued a new set of guidelines warning about the security risks posed by the use of 5G technology in so-called Smart Cities. The ASD's concerns align with those of the Five Eyes security alliance, which has warned that the interconnected nature of a fully connected city makes it vulnerable to cyberattacks.
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?
