RAN
Radio Access Network
The Radio Access Network performs the radio functionality of the network, as well as providing the connection to the CN (Core Network). The RAN typically includes a controller ( RNC (Radio Network Controller) in 3GPP (Third Generation Partnership Project) and BSC (Base Station Controller) in 3GPP2 (Third Generation Partnership Project 2)) and several transmitter/receivers ( Node B in 3GPP, BTS (Base Transceiver Station) in 3GPP2).
