3G UMTS (Universal Mobile Telecommunication System) technology offered much higher data speeds compared to the 2G GSM data networks like GPRS and EDGE. The 3G network had evolved from CDMA2000, 1xEV-DO and WCDMA technologies. Let us study these 3G UMTS CDMA Interview Questions and Answers.
Every single question is a combination of 2-3 questions. Try to memorize questions with "All the above" as the answer.
3G UMTS / CDMA / WCDMA / 1xEV-DO / CDMA2000 Interview Questions and Answers
3GPP2 (Third Generation Partnership Projects) developed standards for 3G CDMA version namely CDMA2000 (IS-2000). 3GPP developed standards for 3G UMTS WCDMA based network. Both versions had evolved from the basic CDMA(IS-95) only. UMTS WCDMA is very polished and efficient. Let us study these 3G UMTS CDMA Interview Questions and Answers.
WCDMA relied upon GPRS architecture to deliver data while CDMA2000 used CDMA way of delivering data to the customers. EVDO (Evolution-Data Optimized) is the technology used by 3G CDMA to deliver reasonable download speeds. Multiple revisions to the EVDO specification led to the 1xEV-DV (Evolution Data and Voice) which is also called UMB (Ultra Mobile Broadband). UMB is treated as a 4G network.
The size of the WCDMA based equipment is less than that of the CDMA2000 counterparts. This saves energy bills for the Telecom vendor in the form of Battery Consumption and Airconditioning. Though 3G is a good technology, people still look forward to 4G and 5G technologies.
