5G technology includes novel tools like massive MIMO and beamforming, which allow 5G networks to deliver faster, targeted cellular signals to customers. 5G also uses a wider range of radio frequencies, including C-band and millimeter-wave frequencies that previously had much fewer commercial and industrial uses. A 5G mobile network also uses small-cell transmitters, basically smaller versions of cell towers. Small cells propagate millimeter-wave radio signals, which can deliver data to your phone at gigabit-plus speeds in densely populated areas. Cellular carriers have also started using software-based networking architecture to make their 5G networks more flexible. The ultimate goal is to use 5G technology like these innovations for many more functions outside of cell phones and internet—including robots, automated factories, and self-driving cars.
