The eNodeB is the sole node type within E-UTRAN and represents a dramatic departure from 3G design. In UMTS the NodeB was a comparatively simple radio transmitter that forwarded everything to a centralized Radio Network Controller for processing. The eNodeB absorbs all of those controller functions directly, performing radio resource management, dynamic scheduling, uplink and downlink power control, inter-cell interference coordination, and header compression right at the cell site. This distributed intelligence is why LTE achieves lower latency and faster handover execution than any previous generation of mobile technology.
