How technically it works, I don't know, but I'm impressed by the "Massive MIMO" name. Sounds as if this will only work in new phones with the new chipset. More antennas=more speed and less congestion. Don't want to get a new phone, though.
More cell phone radiation... guess I need to start wearing tin foil hats.
Let's wait and see what becomes, radiation wise, with the people who fork out $ 1,000 or so for the new phones with the new chipsets. One good thing about the past 4 months with CN is that our exposure to cell phone radiation was kept to a minimum as long as one did not call and get the "welcome to Red Pocket" message that often. Speaking of hats made of metal, perhaps the metal hats shown in the link would ward off radiation.
