The difference of eNodeB, Home eNodeB, Macro eNodeB, Femto cell, Small cell, Pico cell and Micro cell is given below.
eNodeB stands for evolved Node B, where Node B is a term used in UMTS equivalent to the BTS (base transceiver station) description used in GSM. Each eNB is a base station that controls the mobiles in one or more cells. The base station that is communicating with a mobile is known as its serving eNB. It is used to transmit/receive radio data to/from user equipment.
Home eNodeB (HeNB) – This is the 3GPP’s term for a LTE Femto cell or Small cell. It is a small, low-power cellular base station, typically designed for use in a home or small business and belongs to the closed subscriber group (CSG). Its coverage range is less than 10 meters.
Pico cell – It is small cellular base station which is used for a small area such as offices, shopping malls, apartments, railways stations etc. Pico cells are typically used to extend coverage to indoor areas where outdoor signals do not reach well. Its coverage range is less than 200 meters.
Micro cell – Also it is a low power cellular base station which is used to cover less than 2km of area such as transportation hub and resorts etc.
