ACCESS NW

UTRAN (Universal Terrestrial Radio Access NW)

also called as RNS(Radio Network Subsystem),

performs the functions specific to WCDMA air

interface.

UTRAN operates in FDD mode and the two nodes

connected to UTRAN are RNC and Node B.

RNC(Radio NW Controller) replaces BSC and Node

B replaces BTS in GSM arrangement

8/6/2019 1 16 Gprs Edge 3g


UTRAN Features

In the FDD mode the uplink and down link uses

separate frequency bands.

The carrier have a bandwidth of 5 MHz.

The UTRAN chip rate is 3.84 Mcps.

The spreading factor can vary BETWEEN 4 TO 512.
