1.	UMTS use which multiple access technique?(a) CDMA(b) TDMA(c) FDMA(d) SDMAI had been asked this question during an interview.Question is from 3G W-CDMA (UMTS) in chapter Modern Wireless Communication Systems of Wireless/Mobile
Answer» Right choice is (a) CDMA To elaborate: Although UMTS is DESIGNED to operate on EVOLVED GSM core networks, it uses code division multiple access (CDMA) for its air interface. The majority of the 3G systems in operation employ CDMA, while the rest USE TDMA. CDMA allows various users to share a channel at the same time, while TDMA allows users to share the same channel by CHOPPING it into different time SLOTS.
