	UMTS : universal mobile telephony standard, in the UK a WCDMA system
			*Wide-band CDMA: a CDMA protocol originated by NTT DoCoMo and now adopted for third-generation use in Europe, Japan and the United States.
			*WCDMA has become the Direct Sequence (DS) mode in the ITU's(International Telecommunications Union) 3G specification, which includes the 1X Multi-Carrier mode (1X MC) and 3X Multi-Carrier mode (3X MC). 1X MC (formerly known as CDMA2000) and 3X MC comprise the 3G upgrade path for carriers already using CDMA (CDMA One).
			*UMTS : universal mobile telephony standard, in the UK a WCDMA system
			*W-CDMA is based on the Direct Spread CDMA technique. Qualcomm collects royalties for both standards. Qualcomm also collects royalties for another standard called TD-SCDMA (Time Division-Synchronous Code Division Multiple Access), which is also based on Qualcomm's CDMA standard.
