In a mmWave world, turning a corner or spinning in your desk chair might very well mean your device losing the signal. While high frequencies have been used for point-to-point network backhaul links, cellular carriers have never before made common use of these frequencies to serve individual user devices directly. But the dearth of unused spectrum available below 6 GHz, and the huge channel bandwidths available at mmWave, mean that they’re doing so now.
mmWave makes possible blazing 5G speeds that simply can’t be achieved in the single channels available at lower frequencies, but that performance comes with a hefty price in propagation.
