Introduction

In the history of mobile phone technology, 3G will always be remembered with the introduction of smart-phones. But with the technological advancement, telecommunication has also shown rapid evolution. The demand of new generation is mostly in the form of mobility and faster connectivity. Service providers in the field of telecommunication are involved in developing and exploring a next generation which is known as fourth generation (4G). Speed of connectivity has surely increased with this technological advancement in the domain of 10mbps-100mbps (Sullivan, 2012).

Compare and contrast 3G wireless networks to 4G networks

3G has shown a noticeable advancement in the field of telecommunication. It has opened a completely new realm of possibilities by involving applications like stream audio and video, video conferencing, video calling and a variety of multimedia applications whereas applications introduced in 4G are 3D television, IP telephony, video conferencing, amended mobile web access, gaming services as well as high definition mobile television (Agbinya, 2010).
