Cha2,

<< whose use for W-CDMA (called UMTS in Europe to avoid those anethma letters CDMA) >>

In the interest of historical accuracy the Universal Mobile Telecommunications System (UMTS) is an end to end technology platform for global terrestrial and satellite communications, for operation in WRC assigned IMT-2000 spectrum that was created in concept before IS-95 CDMA (cdmaOne) was ever fully commercialized.

The initial draft UMTS standards were created in January 1997 under the auspice of 3GIG. Basic terminology was established at that time. The 2 terrestrial air interfaces (or modes of operation) of UMTS are collectively referred to as UMTS Terrestrial Radio Access or UTRA and they were chosen in January of 1998 by 3GPP and the UMTS forum. One of the 2 (initial) air interfaces (or modes of operation) is IMT-DS (Wideband CDMA or W-CDMA), it operates off a GPRS IP backbone and resides in a subsystem of the Infrastructure called the UTRAN or "access network".

There is a bit more to this than avoidance of the "anathema letters CDMA", just like there is more to UMTS (and GSM/GPRS/GERAN or 1xRTT/1xEV) internetworking and interoperability than a multi-mode, multi-frequency chipset will provide.
