AT&T found a clever, and misleading, many people say, way to get ahead of the field on 5G. By taking its 4G LTE network and increasing the number of connections between a cell tower and phone (4 X 4 MIMO), packing more data into signals (256QAM) and widening a "data lane" (carrier aggregation), the carrier can offer data speeds twice that available on 4G LTE. AT&T calls this 5G Evolution and added a "5G E" icon on the status bar of its handsets that are connected to this network.

Some might consider this to be just plain wrong since most consumers have no idea ...
