I read an article on the Finley Engineering blog that talks about new research with free-space optics. For those not familiar with the term, this means communication gear that communicates directly using light without any wires. The article talks about a Chinese team of scientists who have used light to transmit ultrahigh-definition video signals between high-rise buildings. more
There was a recent article in the Wall Street Journal that noted that the business world still uses a lot of landline telephones. Landline telephones have been steadily disappearing from homes, but are still not gone. I see ISPs still selling a telephone line to 10% or more of passings, and surveys show that the average residential landline penetration rate is still somewhere between 15% and 20%. more
In November, 2016, SpaceX filed a request for approval to launch 4,425 Internet-service satellites using the Ku and Ka frequency bands. The satellites were expected to measure 4 x 1.8 x 1.2 meters. In February, 2018 SpaceX launched two Internet-service test satellites - TinTin A and B - that measured only 1.1 x .7 x .7 meters. Why the size difference? more
We are getting closer to using alternative broadband solutions offered by international companies. Local telecommunication entities will, in this respect, be relegated to resellers. The reality of accessing low Earth-orbiting satellite (LEO) services is now clearly on the horizon. Most of the telcos and governments are not prepared for the potential shock this might cause to the structure of local telecommunications markets. more
ARCchart is selling a new report entitled Mobile Broadband Performance of Carrier Networks. I can't personally justify the purchase, but I notice this wonderful graph in their sample. ARCchart gave mobile users free speed test applications... more
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. more
Several weeks ago, the White House published a document asserting that "America Will Win the Global Race to 5G." The White House should get over it. This is not about America winning any global race to 5G, but the world working together on fundamentally different, complex, new communication networks and services. There are four important points, however. more
On November 15, the FCC approved a revision to the plan for Starlink, SpaceX's forthcoming broadband satellite service. The new plan reduces the number of satellites from 4,525 to 4,409 and lowers the altitude of the phase-1 satellites from 1,100 to 550 km. Mark Handley, a professor at University College London, has created videos based on simulations he ran of both the original and revised phase 1 plans. more
The FCC's Wireless Telecommunications Bureau today granted temporary spectrum access to 33 wireless Internet service providers serving 330 counties in the U.S. to help them serve rural communities facing an increase in broadband needs during the COVID-19 pandemic. more
In a previous post, I suggested that Cuba might be able to leap over 4G to 5G wireless infrastructure using satellite and terrestrial networks for backhaul. While that would require political and policy change, it would be a good fit with Cuban culture and skills. Before talking about Cuba, let me say a bit about wireless generations. Each mobile technology generation used new technology and enabled new applications. more
Last month, the Chinese government published space situational awareness and traffic management regulations and procedures designed to guard against collisions in orbit and mitigate space debris, and this month, at the G7 summit, delegates from Canada, France, Germany, Italy, Japan, the USA, the UK, and the EU pledged to take action to tackle the growing hazard of space debris as our planet's orbit becomes increasingly crowded. more
My friend Om Malik, dean of the telecom bloggers, posted on the importance of the Federal Communications Commission Chair appointment Obama will make as President... Om is dead on about the importance of this appointment. Decisions made by the five member FCC commission have had and will have an enormous effect not only on the tech sector but on the entire US and even the global economy. more
Google has undertaken a beta-test of a telephony platform that includes the opportunity to route incoming calls to multiple devices and telephone numbers as well as free domestic long distance service. Google offers a service that fits somewhere between computer-to-computer, Internet telephony and Voice over the Internet Protocol telephony with access to and from the public switched telephone network. These service categories present polar opposites for U.S. regulatory purposes... more
As the IEEE 802.11 task force turns its attention to developing Wi-Fi 8, the next iteration of wireless networking standards, the focus has shifted from sheer speed to enhancing user experience. more
Alphabet's Loon on Monday announced that its high-altitude balloons are now providing internet service in Kenya to subscribers of Telkom Kenya. more
