What are the functions of RNC node B in UMTS?

The RNC undertakes the radio resource managementand some of the mobility management functions, although notall. It is also the point at which the data encryption / decryptionis performed to protect the user data from eavesdropping. NodeB: Node B is the term used within UMTS to denotethe base station transceiver.

How does LTE work?

How does LTE work? LTE changes the currentmethod of moving data to an internet protocol system. Rather thanmove small amounts of data, as both CDMA and GSM do, it willmove large packets of data and streamline the service. As such, GSMwas improved to HSPA, or high speed packet access.
