Node-B is a term used in UMTS to denote the BTS (base transceiver station). In contrast with GSM base stations, Node B uses WCDMA as air transport technology. As in all cellular systems, such as UMTS and GSM, Node B contains radio frequency transmitter(s) and the receiver(s) used to communicate directly with the mobiles, which move freely around it. In this type of cellular networks the mobiles cannot communicate directly with each other but have to communicate with the BTSs.
RNC (Radio Network Controller) - The main element in the radio network subsystem that controls the use and reliability of radio resources.
GSN - GPRS (General Packet Radio Service) Support Node
