5G macro / micro-cell power supplies

Data demands are constantly rising and for the next generation of Edge cloud computing, IoT devices, Intelligent Transport Systems and of course live streaming of high-definition AR / VR video, 5G infrastructure will be vital. It takes us from the existing classical network structure to a Software Defined Network, requiring the smallest, most efficient power supplies for macro (10–20 KW) and micro (500 W to 2 KW) cells that will to keep us all connected 24/7.
