WCDMA basics
In this section, you will find a short introduction to WCDMA system parameters.
We will look at the following aspects of a WCDMA system:
– WCDMA frequency bands
– Channel arrangement
– UARFCN
– UE power classes
WCDMA frequency bands The table below shows the specifications for the various WCDMA bands.
Channel arrangement The following sections provide information concerning channel spacing, channel
raster, channel number and UARFCN.
Channel spacing
The channel spacing is 5 MHz. However, to optimise performance in a specific
deployment scenario this value can be adjusted.
Channel raster
The channel raster is 200 kHz.
Channel number
The UARFCN (UTRA Absolute Radio Frequency Channel Number) designates the
carrier frequency.
