sentences:  Server-side implementations of Cooperative MIMO were the first to be adopted into the 4G cellular specifications and are essential for 5G.CoMP and Fixed Relays pool baseband processing resources in data centers, enabling dense deployments of simple, inexpensive radio terminals (such as remote radio heads) instead of cellular base stations.This allows processing resources to easily scale to meet network demand, and the distributed antennas could enable each user device to be served by the full spectral bandwidth of the system.
