AT&T has announced that it will shut down all 3G networks by February, 2022. This current 3G harvesting is the first phase and other carriers will follow. Cellular carriers, like AT&T, will continue to manage their core asset which is cellular spectrum. Consumer demand is the core driver of technology advancements such as these, and cellular carriers will continue to launch new technologies and retire older technologies to better allocate their resources. The end result will be better service and improved communications.
