1.	UMTS does not has backward compatibility with ____________(a) GSM(b) IS-136(c) IS-95(d) GPRSI got this question during an interview for a job.I'm obligated to ask this question of 3G W-CDMA (UMTS) topic in portion Modern Wireless Communication Systems of Wireless/Mobile
Answer» Correct option is (c) IS-95 The explanation is: UMTS assures backward compatibility with the SECOND GENERATION GSM, IS-136 and PDC TDMA TECHNOLOGIES. It is also compatible with all 2.5G TDMA techniques like GPRS and EDGE. But it does not provide compatibility to CDMA technologies of 2G and 2.5 G. IS-95 is a CDMA standard of 2G.
