5G refers to the fifth generation of wireless telecommunications standards, used for cellular networks. It is the successor to the 4G cellular networks that have enjoyed global adoption since the early 2010s. 5G offers theoretical speeds as high as 1-2 Gigabits per second.

Points to Remember:

  • The 5G frequency spectrum is divided into millimeter waves, mid-band and low-band. The millimeter wave offers the fastest speeds, while the mid-band is the most commonly deployed due to range limitations of the millimeter wave.
  • Mainstream global deployment for 5G began in 2019.
