Submission + - 5G's Waveform Is a Battery Vampire (ieee.org)
Adopting that proposal may have also meant pushing some decisions down the road. One such decision concerned how 5G networks should encode wireless signals. 3GPP’s Release 15, which laid the foundation for 5G, ultimately selected orthogonal frequency-division multiplexing (OFDM), a holdover from 4G, as the encoding option.
But Release 16, expected by year’s end, will include the findings of a study group assigned to explore alternatives. Wireless standards are frequently updated, and in the next 5G release, the industry could address concerns that OFDM may draw too much power in 5G devices and base stations. That’s a problem, because 5G is expected to require far more base stations to deliver service and connect billions of mobile and IoT devices.
And Kimery notes that these concerns apply beyond 5G handsets. China Mobile has “been vocal about the power consumption of their base stations,” he says. A 5G base station is generally expected to consume roughly three times as much power as a 4G base station. And more 5G base stations are needed to cover the same area.

But that's a good thing. Yes, it's a pain in the ass for the parents. But hey, nobody said parenthood was supposed to be simple or painless. I sometimes lament that sperm count isn't more closely related to IQ.

religious brainwashing early in life. Innocent children are taught that they should be unquestioningly accepting of wacky ideas just because their elders seem to believe them. Their natural scepticism is denounced as heresy.
The whole idea that anything should just be accepted as a matter of faith is a threat to democracy. Sunday school is clearly a form of child abuse. (even when it's done on Saturday)
