Also, high data rates can end up being more power efficient because of the lower duty cycle; to transfer a given amount of data, the radio doesn’t need to work as long on a link with a higher data rate. So if your 5G is, say, 10x as fast as your 4G under the same conditions, your radio only needs to be in use 1/10 as long. That not only saves you power, but also increases the overall capacity of the network cell, since your time slots are much shorter. (Yes, first generation radios for any new wireless generation are power hungrier than radios for prior generations, but that always gets resolved within a few years.) |

truth be known, its for the internet of things & the 4th industrial revolution. this is when science fiction becomes science fact. as setout by the World Economic Forum |

--- Quote from: nali on January 08, 2022, 11:40:07 am ---There's another aspect to 5G which doesn't seem to make the headlines which is high accuracy location services with 1m or better claimed accuracy. I know that one area of interest is personal navigation for the blind where 10m GPS doesn't really cut it. https://www.ericsson.com/en/blog/2020/12/5g-positioning--what-you-need-to-know --- End quote --- I think it is because they deliberately under-play it after privacy advocates raised concerns. Do you really want them to know you are having diarrhea today because they can mapped you visiting the bathroom every 10 minutes for the whole day? I like the technology, but I am one of those very concerned about the lost of privacy and liberty enabled by these new technologies. |

--- Quote from: Cerebus on January 07, 2022, 08:44:46 pm ---Sure, it comes with some definite, solid technical improvements and advantages. But, and it's a big but, is that it is also driven by political and personal forces that have nothing to do with whether it's a good idea/necessary/justified. --- End quote --- I mean, the technical improvements that allow serving more data to more people faster are pretty much justification enough? Certainly if you look at mobile data usage trends over the past 10 years and projections on demand for the next 5 years, 5G looks pretty desirable. Certainly some people will claim that "it's all cat pictures and tiktoks so we shouldn't be enabling increased usage", but who the fuck are they to decide what usage (and always by implication which people) are important? --- Quote ---On the professional side every waste-of-space manager in telecoms from the boards of Fortune 500 companies down to the lowest line manager wants '5G' on their CV/resumé and will make decisions to facilitate that regardless of the merits of 5G itself. --- End quote --- That is true of literally everything, not even just in technology. People who aren't directly involved see something they hear will be important and they want to get in on it. It's as annoying as it is predictable, but it isn't any sort of reason to be upset about 5G. It's just a fact of being human. But with or without the hangers-on, the case for 5G is pretty clear, and the people actually working on it understand that. |

story goes like this the US minister of transportation one Buttigieg was multitasking between breastfeeding baby's and doing that transportation stuff so forgot about 5G and airport 5G microwave interference with aircraft altimeters. a US government cockup or blunder of the first order. https://www.dailymail.co.uk/news/article-10413625/British-flyers-warned-caught-5G-chaos.html https://www.eenewswireless.com/news/5g-interference-radio-altimeters-raises-aircraft-safety-concern |
