Why WCDMA called Wideband?

+1 vote

Probably a simple question, 3G WCDMA systems have 5MHz bandwidth (one direction). 5MHz is neither wide nor narrow; then why it is called WCDMA.

Yes, 5MHz is neither wide nor narrow; it is just the bandwidth.

They named it as WIDE for having a reference with 2G-CDMA systems. In 2G-CDMA systems the bandwidth is 1.25 MHz and in WCDMA it is 5 MHz bandwidth (one direction). That's the reason it is called as Wide Code Division Multiple Access.

Is there anything in the specs that mentions that “ue-not-available-for-ps-service” can also be used for CSFB to WCDMA as well? So far what I have seen from 23.272 section 6.3 is specific to GERAN as target RAT.

After a handover from LTE to WCDMA I noticed that there is always "Activate PDP context request" message.
However, in documentation, I found multiple call flows without that message, but with "Update PDP context".
What causes these differences?

Thank you.
