A nice place to discuss rumors, happenings, innovations, and challenges in the technology sphere. We also welcome discussions on the intersections of technology and society. If it’s technological news or discussion of technology, it probably belongs here.
Remember the overriding ethos on Beehaw: Be(e) Nice. Each user you encounter here is a person, and should be treated with kindness (even if they’re wrong, or use a Linux distro you don’t like). Personal attacks will not be tolerated.

The part about beamforming also has another side effect that all the conspiracy theorists won't like. Although they can likely spin this in some other sinister way. Beamforming allows for essentially less electromagnetic pollution than previous Generations. Because it directs the energy more directly where it's needed instead of just broadcasting it everywhere. Way more efficient. Although I can already see how the Conspiracy nuts start shouting that this will be used to shoot concentrated beams of 5G on the enlightened people...
The funny thing is that beamforming isn't some laser that the tower can aim at people people with.
The technique for tuning a beamforming signal is to see which antennas a signal is coming on (on your 100 antenna array), and then boost the gain/match the phase on those antennas to match. It's just linear algebra, not a cannon.
Also most wifi routers do beamforming, too.
