What is eNodeB?

A base station for a cellular network is typically composed of a tower and equipment hut, and is sometimes referred to as a cell site. The cell site usually has equipment that supports a number of different cell towers, each serving a different sector of the surrounding area. The term "eNodeB" refers to the base station equipment that handles the radio interface with the mobile devices.

The eNodeB is responsible for managing the radio resources for the cell, and for handling the radio link protocols with the mobile devices. It also performs other functions such as mobility management, handover, and authentication. The eNodeB is connected to the core network via a high-speed backhaul link, and is typically controlled by a network management system.
