Remote Radio Head or RRU: Remote Radio Unit.  Remote radio heads increase a base station’s efficiency and facilitate easier physical location for gap coverage problems. The RRH contains the base station’s RF circuitry plus analog-to-digital/digital-to-analog converters and up/down converters. RRHs also have operation and management processing capabilities and a standardized optical interface to connect to the rest of the base station.
