Node B
In the UMTS architecture, Node B is the base station that provides the radio interface between mobile devices and the UMTS Terrestrial Radio Access Network. The definition, interfaces, and functional responsibilities of Node B are specified in the 3GPP TS 25.401 standard and related specifications, including: radio transmission and reception, power control, modulation and coding, the physical radio interface, radio resource management, and forwarding user data and signaling to a Radio Network Controller, which manages connections to the core network.
