Abstract

Mobile communications systems revolutionized the way people

communicate, joining together communications and mobility. A

long way in a remarkably short time has been achieved in the

history of wireless. Evolution of wireless access technologies is

about to reach its fourth generation (4G). Looking past, wireless

access technologies have followed different evolutionary paths

aimed at unified target: performance and efficiency in high

mobile environment. The first generation (1G) has fulfilled

the basic mobile voice, while the second generation (2G) has

introduced capacity and coverage. This is followed by the third

generation (3G), which has quest for data at higher speeds

to open the gates for truly “mobile broadband” experience,

which will be further realized by the fourth generation (4G).

The Fourth generation (4G) will provide access to wide range

of telecommunication services, including advanced mobile

services, supported by mobile and fixed networks, which are

increasingly packet based, along with a support for low to

high mobility applications and wide range of data rates, in

accordance with service demands in multiuser environment.

This paper provides a high level overview of the evolution of

Mobile Wireless Communication Networks from 1G to 4G.
