UMTS radio access network, UTRA or UTRAN was the name for the radio access network elements of the 3G UMTS mobile phone system .
Read moreWhat is Geran and UTRAN?
GSM EDGE Radio Access Network (GERAN) is a radio access network architecture, based on GSM/EDGE radio access technologies . The GERAN is fully harmonised with the UMTS Terrestrial Radio Access Network (UTRAN) through a common connectivity to the UMTS core network.
Read moreWhat are the major functions of the RNC in UTRAN architecture?
The Radio Network Controller (RNC) is a governing element in the UMTS radio access network (UTRAN) and is responsible for controlling the Node Bs that are connected to it .
Read moreWhat does UMTS stand for?
Universal Mobile Telecommunications System (UMTS)
Read moreOn what is the UMTS air interface based on?
UMTS air interface is based on DS CDMA , that is, user data bits are multiplied with a spreading sequence (consists of random bits called chips) and chip rate is much higher than symbol rate or data rate. This process spreads the user data signal to wider frequency band.
Read moreWhat are the interfaces of UMTS?
There are four interfaces connecting the UTRAN internally or externally to other functional entities: Iu, Uu, Iub and Iur . The Iu interface is an external interface that connects the RNC to the Core Network (CN). The Uu is also external, connecting Node B with the User Equipment (UE).
Read moreHow does UMTS network work?
UMTS relies on a packet-switched system . This allows cellular devices to send small “packets” of data to a destination, whereas circuit-switched networks require a point-to-point connection. In an old phone network, making a call meant reserving a line between the sender and receiver.
