Over two years ago, an MIT research group ran a simulation of the low-Earth orbit broadband constellations of OneWeb, SpaceX, and Telesat, and last January they repeated the simulation updating with revised constellation characteristics and adding Amazon's Project Kuiper. They ran the new simulation twice, once using the planned initial deployments of each constellation and a second time using the configuration shown. more
Most carriers don't order 200,000 5G base stations, so they will pay more, but that's the actual price for the joint procurement of China Telecom and China Unicom. The 200,000-300,000 cells the two jointly are upgrading are probably more than the entire rest of the world will add. The second Chinese network, jointly built by China Mobile and China Broadcast, is growing even faster. more
I remember that soon after the City of Chattanooga launched its citywide fiber network, the company held a competition seeking web applications that would benefit from gigabit speeds. I don't recall if anything useful came out of that effort, but I know that there are still today almost no big bandwidth applications on the web online aimed at the average household. more
Elon Musk packed a lot about SpaceX and Starlink into a 32-minute interview at the 2021 Mobile World Congress and ended with a discussion of his motivation and the roles of his three companies - SpaceX, Starlink, and Neuralnk. Let's start with the SpaceX and Starlink update and conclude with the philosophy and motivation. (Scroll to the end of the post for the video of the interview). more
As U.S. Congress inches closer to an infrastructure bill, the industry is feverously speculating how a broadband infrastructure plan might work. There is still a lot of compromise and wheeling and dealing to be done, so nobody knows how a final broadband program might work, or even definitively if there will be one. But since this is the billion-dollar question for the industry, it's worth a review of the possibilities. more
FIOS by Verizon, is a bundled Internet access, telephone, and television service that operates over a fiber-optic communications network with over 5 million customers in nine U.S. states -- providing Fiber to the Home (FTTH). One of the first service areas was a Northern Virginia community known as Ashburn -- which is also is the cloud data center capital of the world. It literally sits on top of the most massive mesh of high bandwidth, low latency fiber in existence. more
The National Telecommunications and Information Administration surprised the broadband industry by issuing a new broadband map for the whole U.S. The map differs in dramatic ways from the FCC's broadband map, which is derived from broadband speeds that are reported by the ISPs in the country. It's commonly understood that the FCC broadband map overstates broadband coverage significantly. The NTIA map draws upon varied sources in an attempt to create a more accurate picture of the availability of broadband. more
I read a blog on the WISPA website written by Mark Radabaugh that suggests that the best policy for broadband speeds would be met by asymmetrical architecture (meaning that upload speeds don't need to be as fast as download speeds). I can buy that argument to some extent because there is no doubt that most homes download far more data than we upload. But then the blog loses me when Mr. Radabaugh suggests that an adequate definition of speed might be 50/5 Mbps or 100/10 Mbps. more
A little over a year ago, the FCC approved the use of 1,200 MHz of spectrum in the 6 GHz band for public use -- for new WiFi. WiFi is already the most successful deployment of spectrum ever. A year ago, Cisco predicted that by 2022 that WiFi will be carrying more than 50% of global IP traffic. These are amazing statistics when you consider that WiFi has been limited to using 70 MHz of spectrum in the 2.4 GHz spectrum band and 500 MHz in the 5 GHz spectrum band. 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
