America has some of the worst, most expensive broadband in the developed world, thanks to massive market concentration, grotesque regulatory capture, and systematic underinvestment in crumbling telcoms infrastructure.
Predictably, every time one of the rent-seeking ISP profiteers (or their regulatory water-carriers) is called out on this, they dangle something shiny that they insist will solve all these problems. These days, that's 5G, a technology for delivering wireless broadband to devices close to its antennas that does nothing at all to solve the slow speeds in the lines connecting those towers to one another.
Writing for EFF Deeplinks, Bennett Cyphers and Ernesto Falcon lay out the case for fiber (top speed, 100tbs) and for not believing the 5g (top speed, 10gbs) hype.
America can still have a fiber future, but only if we stop pretending that 5G will solve America's worst-of-breed internet connectivity.
Gigabit and faster wireless networks have to rely on high frequency spectrum in order to have sufficient bandwidth to deliver those speeds. But the faster the speed, and the higher the frequency,the more environmental factors such as the weather or physical obstructions interfere with the transmission. Gigabit 5G uses “millimeter wave” frequencies, which can’t travel through doors or walls. In essence, the real world environment adds so much friction to wireless transmissions at high-speeds that any contention that it can replace wireline internet fiber or cable—which contend with few of those barriers due to insulated wires— is suspect.
Meanwhile, fiber systems have at least a 10,000 (yes ten...thousand) fold advantage over cable systems in terms of raw bandwidth. This translates into a massive advantage for data capacity, and it’s why scientists have been able to squeeze more than 100 terabits per second (100,000 Gb/s) down a single fiber. The most advanced cable technology has achieved max speeds of around 10 Gb/s in a lab. Cable has not, and will not, come close to fiber. As we explain in our whitepaper, fiber also has significantly less latency, fewer problems with dropped packets, and will be easier to upgrade in the future.
Why Fiber is Vastly Superior to Cable and 5G

America's telcoms sector is hugely concentrated and corrupt, and systematically underinvests in maintenance and infrastructure even as it gouges customers, which it can get away with thanks to its monopoly power, leaving Americans with some of the world's worst, most expensive communications services.
The past two years have seen a tremendous shift in the public perception of capitalism and socialism, the character of philanthropy as reputation-laundry rather than generosity, and the nature of wealth as an indicator of sociopathy, not virtue or cleverness.
Elizabeth Warren has released a characteristically detailed campaign plan to counter white nationalist violence in the USA, whose multi-pronged approach includes directing the DoJ to be more vigorous in pursuing white nationalist groups (and to lay off the Cointelpro-style surveillance of groups that advocate for protections for racialized people); centralized data collection on white nationalist […]
Building blocks are among a child’s first, and arguably, most important, toys. Once they start stacking one tentatively on top of another, the blocks not only spark waves of creativity, but actual real-world understanding of scientific principles like engineering and physics. It wouldn’t even be a stretch to call blocks on of the first true […]
Time management and self-motivation, the ability to stay on task and achieve in the office or when you’re working with home, is the true test of any person’s professional mettle. While that’s easier said than done, those skills can be taught and developed as you’ll find in The 2020 Work From Anywhere Hacker Bundle. The […]
It’s easy to be instantly dismissive about most Bluetooth speakers, especially small travel-sized units. Over the past few years, makers of every shape, size, and variety have started pounding out Bluetooth speakers, many barely able to sound much better than your smartphone speaker, let alone provide the bass and volume heft of legitimate portable speakers […]
