Modern day cellular mobile networks use Massive MIMO technology to extend range and service multiple devices within a cell.
This becomes increasingly problematic when we are creating a society where wireless access is supposed to be ubiqui.
Nevertheless, one of the characteristics of this technology is large variations in the quality of service dependent on where the end user is located in any given cell.
This has brought tremendous improvements in the high peak data rates that can be handled.
