      Wireless data has been sent at 938 gigabits per second, the equivalent of downloading more than 20 average-length movies a second. This could allow for vastly faster information transfer, even in crowded spaces where many people are using their phones.

      I don’t think the extra bandwidth from using spectrum beyond current mmwave is all that useful. Its not like you can really get it anywhere as it is due to frequency issues.

      There are too many issues here to even begin commenting on it…

      With even less penetration in buildings right? I feel like 5G is good enough….

      In laboratory experiments mean very little in the real world. How many actually get 5g speeds consistently right now? Just because in a laboratory under controlled conditions you can download “theoretically” 20 movies a second means very little in the real world under “less than ideal settings”, provider dead zones, and interference. Here’s an idea, fully perfect the rollout of 5g first instead of leaving us in the lurch as they go off chasing the next speed unicorn

      How fast do we need porn to load. We already have a premature ejection problem.

      This is point-to-point transfer using mm wave. By using pairs of optically locked lasers they were able to reduce the gap between different bands to 300 MHz, which allowed them to squeeze in more transmission “lanes”. It doesn’t look like a viable portable setup, but it may be useful for relaying high-bandwidth signal between towers.

      Not sure if using optically locked lasers is something that can be easily built into a base station, seems like a expensive and complicated solution. But there may be other ways to generate a phase-locked signal pair, so at least it may point to a research direction.

      That would be great IF I COULD GET A FUCKING SIGNAL IN THE FIRST PLACE.

      With even less range! For reference, the best 6G can do is about 100 meters. Because of the high frequencies it’s far more subject to rain fade than 4G frequency ranges (much like 5G but worse!).

      There is one use for this though – fixed wireless internet service.

      Hopefully this will eventually help lower the cost of Internet

      Frankly, going from 4G to 5G didn’t make much difference to me. 4G was already good enough for most purposes when there was good signal, and when signal is bad, it doesn’t matter much whether it is 4G or 5G that is bad, it is just bad.
