5G WIRELESS ARCHITECTURE

ABSTRACT
This document represents personal views on 5G network architecture, especially for wireless service providers. Document has 3 segments, Brief history of wireless telecommunication, 4G network architecture, Network Infrastructure sharing and 5G network architecture.

We are living in era of convergence. Convergence is merging of technologies, domain and
discrete IT systems. Basic of convergence lies in Digitization. The digitization of everything is
creating a more natural communications experience. Boundaries separating various technologies, engineering practices, functions etc. are dissolving. So tomorrow, our car, our mobile phone, our home security system, our office, all the systems that surround us, will communicate with each other automatically to fill our environment with our preferences and our need to feel connected anywhere, anytime and with anyone, across the world. This is called Ubiquitous Computing paradigm.
Wireless technologies are going to take taking new dimension in our lives. The wireless
broadband will soon become readily available to everybody while, being at home, driving the car, sitting in the park, and even on a pleasure boat in the middle of a lake. And because of this, our need to have information at anytime and to be connected at all places, all the time, will be satisfied.
Brief History of Telecom
Moore’s law
The way that "Moore's Law" is usually cited is: "the number of transistors that can be fit onto a square inch of silicon doubles every 12 months." Moore's law describes a long-term trend in the history of computing
hardware but it also prove true for wireless technologies. From 1G (First Generation) to 4G (4th Generation), wireless bit rate has increased from 2.4 Kbps to 100 Mpbs.
Brief description of Wireless Generations:
1G:
The first generation, 1G wireless mobile communication systems, was introduced in the early 1980s and completed in the early 1990s. 1G was analog and
supported the first generation of analog cell phones with the speeds up to 2.4kbps. The
prominent ones among 1G system were advanced mobile phone system (AMPS), Nordic mobile telephone (NMT), and total access communication system (TACS)
2G:
The second generation, 2G system, fielded in the late 1980s and finished in the late 1990s, was planned mainly for voice transmission with digital signal and the speeds up to 64kbps. GSM and CDMA IS 95 were prominent technologies.
2.5G
2.5G is used to describe 2G-systems that have implemented a packet switched domain in addition to the circuit switched domain. 2.5 G can provide data rate, up to 144 kbps. GPRS, EDGE and CDMA 2000 were 2.5 technologies.
3G:
The third generation, 3G wireless system, was developed in the late 1990s and might be well-
done in the late 2000s. 3G is not only provided the transmission speeds from 125kbps to 2Mbps, but also included many services, such as global roaming, superior voice quality and data always add-on. UMTS, CDMA Evdo, HSPA are 3G technologies.
4G:
The fourth generation (4G) is a conceptual framework and a discussion point to address future needs of a high speed wireless network that can transmit multimedia and data to and interface with wire-line backbone network perfectly just raised in 2002. The speeds of 4G can theoretically be promised up to 1Gbps. LTE is considered as 4G technology.
4G Architecture
4G 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), minimal services like voice and data, and other services that utilize bandwidth. The definition of 4G is to provide adequate RF coverage, more bits/Hz and to interconnect all wireless heterogonous networks to provide seamless, consistent telecom experience to user.
