5G Technology of Mobile Communication

The modern world is shrinking due to the development of science and its technology. Over the years, wireless telecommunication market has long been recognized as one of the most dynamic and fastest growing segments of the global telecommunication industry. But requirement of human being augment day by day. However further modernization will be on convergence of the existing technology in to a single platform. Mobile broadband is becoming a reality, as the internet generation grows accustomed to having broadband access wherever they go and not just at home or in the office. This paper mainly focuses on how a 5G network can provide more approach to a common man to utilize his available possessions in an immense way to make him to feel the real progress.

This Advanced Mobile Phone System (AMPS) was a frequency modulated analog mobile radio system using Frequency Division Multiple Access (FDMA) with 30kHz channels occupying the 824MHz − 894MHz frequency band and a first commercial cellular system deployed until the early 1990’s.[1] The second generation (2G) wireless mobile systems are digital cellular systems. Comparing with the first generation, the second generation wireless system used digital modulation scheme, such as time division multiple access (TDMA) and code division multiple access (CDMA). Based on the two techniques, there were three primary 2G mobile communication systems. They are TDMA (IS-136), CDMA (IS-95), and GSM. TDMA (IS-136), as a completely digital system, was deployed in North America in 1993, but operated in the AMPS frequency band of 824MHz-894MHz. CDMA (IS-95) systems using Direct Sequence Spread Spectrum (DSSS) are working on the 1850-1990 MHz frequency band to support CDMA carriers.[1] Third generation: An attempt to establish an international standard for 3G mobile is being moderated through the ITU, under the auspices of its IMT-2000 program. It was inveterate in late 2000.It provides transmission speed up to 2Mbps. Third generation (3G) services combine high speed mobile access with Internet Protocol (IP)-based services. Apart from transmission speed innovative enhancement was made in Quality of services. Add on services such as global roaming, better voice quality, always on made 3G as a significant generation.[2] 4G is an abbreviation for Fourth-Generation, is a term used to describe the next complete evolution in wireless communications. The approaching 4G (fourth generation) mobile communication systems are projected to solve still remaining problems of 3G (third generation) systems and to provide a wide variety of new services, from high-quality voice to high-definition video to high data-rate wireless channels. The term 4G is used broadly to include several types of broadband wireless access communication systems, not only cellular telephone systems. One of the terms used to describe 4G is MAGIC—Mobile multimedia, anytime anywhere, Global mobility support, integrated wireless solution, and customized personal service.[2] 1.1 5G: While considering a smooth migration for 5G it is apparent that it should be valid for all sorts of radio access technologies. So that it could make better revenue for current global operators as well as interoperability will become more feasible. To make 5G practical for all sorts of radio access technologies there should be a common platform unique for IJECSE,Volume2,Number 4 Puneet kumar et al. ISSN 2277-1956/V2N4-1265-1275 all the technologies. One of those unique platforms is Flat IP network. Certainly Flat IP network is the key concept to make 5G acceptable for all kind of technologies. To meet customer demand for real-time data applications delivered over mobile broadband networks, wireless operators are turning to flat IP network architectures. Flat IP architecture provides a way to identify devices using symbolic names, unlike the hierarchical architecture such as that used in "normal" IP addresses.[2] 1.3 5G ARCHITECTURE Fig. 1.1 5G mobile phone design [3] Fig.1 shows 5G mobile phone design. 5G is being developed to accommodate the QoS and rate requirements set by forthcoming applications like wireless broadband access, Multimedia Messaging Service (MMS), video chat, mobile TV, HDTV content, Digital Video Broadcasting (DVB),[3] minimal services like voice and data, and other services that utilize bandwidth. The definition of 5G is to provide adequate RF coverage, more bits/Hz and to interconnect all wireless heterogeneous networks to provide seamless, consistent telecom experience to the user. [3] 1.4 Evolved Packet Core (EPC) Evolved Packet Core is the IP-based core network defined by 3GPP (Telecom standard) for use with LTE and other access technologies. The goal of the EPC is to provide simplified all IP core network architectures to efficiently give access to various services such as the ones provided by IMS (IP Multimedia Subsystem). EPC consists essentially of a Mobility Management Entity (MME) & access agnostic gateway foe routing of user datagram. EPC will be a completely new architecture for wireless operators, one that emulates the IP world of data Communication rather than the voicecentric world of wireless. EPC is based on flat IP network theory.
