Introduction Since contemporary communication came into daily life, people always keep seeking unrestricted communication at all time. Mobile telecommunication satisfied peoples demand with the first generation (1G) and the second generation (2G). In the wake of development in multimedia and internet, most of telecommunication mobile networks operators have offered the third generation (3G) to the customers to replace 2G over the past two years. Currently, many ICT professionals and research†¦show more content†¦The core technology of 4G is orthogonal frequency-division multiplexing (OFDM) which belongs to Multi-Carrier Modulation (MCM). It divides assigned channel into orthogonal sub channels, modulating and transmitting on each sub channel of narrowband (Aceà ±a 2005). 3.2 Telecommunication system structure 3G is based on cellular network (shown in Figure 1), the core network of 3G is developed from GSM-MAP, AMPS and ANSI-41 which is the core network of GSM, the air in terface and the corresponding system is backward 2G compatibility (Luo et al. 2003).

Zhao 10810164 University of Technology, Sydney 32702 Contemporary Telecommunications But contemporary communication requires to provide mobile user multimedia service over broadband to enable full function of next generation mobile network based on internet technology. As the 3G core network evolved from the 2G, it is not the optimal system that processing Transmission Control Protocol / Internet Protocol (TCP / IP) packets. Meanwhile, it cannot handle data transmission with containing large images and information either. Therefore, a critical need is to create a new telecommunication network with the optimal transmission of TCP / IP data packet, it would be completely different from the 2G and 3G wireless networkShow MoreRelatedNetwork Speed - 4G Technologies Essay1402 Words   |  6 PagesOverview [WINNIE] As the technology world evolves and develops faster and better every day, it puts new demands of speed and throughput on the network that supports it. Today especially, we live in a world where everyone is mobile, and it is expected that mobile networks keep pace with the innovations in technology.
