back to article Optical boffins tweak antennae with photons so MIMO can make WiFi serve more masters

Phased-array antennas, a technology crucial to modern Wi-Fi systems that use beam-forming to improve throughput, has a speed limit in how quickly beams can be manipulated. Beams are formed by adjusting a microwave signal's timing at different antennas in a multiple-in, multiple-out (MIMO) system so that they reinforce in some …

    This is astonishing.

    Phase shifting at rates of 1ns is very impressive.

    And let's be honest, who expected this from the land of the midnight Barbie?

      Quite a few since they were instrumental in developing WiFi (including some of the first patents which still form the fundamentals of making WiFi work) though admittedly it was byproduct of looking for black holes with radio telescopes

    Nice

    Very clever, how long before it appears in commercial products?
