AT&T Continues to Bring 5G Experiences to Life

5G will ultimately unlock use cases that are dependent on faster speed, wide coverage, and low latency. Think of this as the next frontier in untethering, giving you the ability to take the ultra-fast experience you have in your home or business with you virtually anywhere.


Spectrum Bands

Until recently, mobile operators believed that 3 GHz was the upper limit of “usable” spectrum or frequencies for terrestrial mobile service necessary to provide commercial mobile broadband services. Today, however, new use cases, such as providing HD video to customers, along with technology advancements, have expanded the potential frequencies for terrestrial mobile broadband use – well into the millimeter wave bands or those bands above 24 GHz.
