Abstract
Over the past decade, wireless communications has seen an exponential growth and will certainly continue to witness spectacular developments due to the emergence of new interactive multimedia applications and highly integrated systems driven by the rapid growth in information services and microelectronic devices. So far, most of the current mobile systems are mainly targeted toward voice communications with low transmission rates. In the near future, however, broadband data access at high transmission rates will be needed to provide users packet-based connectivity to a plethora of services. It is also almost certain that the neXt Generation (XG) wireless systems will consist of complementary systems with a set of different standards and technologies along with different requirements and complementary capabilities that will offer users ubiquitous wireless connectivity between mobile and desktop computers, machines, game systems, cellular phones, consumer electronic products, and other hand-held devices. A key requirement in future wireless system is their ability to provide broadband connectivity with end-to-end Quality of Service (QoS), a high network capacity, and throughput at a low cost. To support the above services, a host of new issues and problems have to be addressed. This talk will discuss the challenges facing the 3G communication networks and at some of the important issues pertaining to the evolution of mobile communication networks from GSM (Global System for Mobile Communications) to GPRS (General Packet Radio Service) to 3G (Third Generation - CDMA and WCDMA) and will also describe some of the leading enabling technologies and comparison of CDMA2000 and WCDMA
The technical report (under project resources) contains the overview of evolution from 1G to 3G, and a brief introduction to CDMA2000. Channelization in CDMA2000 is covered in much detail. Some research papers are also mentioned which were studied during the course.
