Exciting times, was prepping for this while applying to Ericsson.
5G is not just about increasing the Bandwidth compared to 4G - it “represents a fundamental rearchitecting of the access network in a way that leverages several key technology trends and sets it on a path to enable much greater innovation”.
In the same way that 3G defined the transition from voice to broadband, 5G’s promise is primarily about the transition from a single access service (broadband connectivity) to a richer collection of edge services and devices.
For more of the vision, see Qualcomm note.
5G is standardized by the 3rd Generation Partnership Project.
