Abstract
By examining the two papers on 4G and 3G, namely wireless networks: opportunities and challenges by Hassan Gobjuka, Verizon, 919 hidden bridge irving, Tx 75038 and wireless network: opportunities and challenges emphasis us to throw light on the differences between the two networks. This task is being done in order to list out the drawbacks and merits of these two evolutions of the networks and further to implement R&D research to bring out their sparks in this modern era.

The differences are done on the following Index terms: Background difference, definitions, technologies progress, speed/ rate of transmission, switching technologies used, network, band width, design specification, QoS, service and billing, features and capabilities.

Keywords: RAN,
NETWORK,SGSN

1. Introduction:
3G is also called third generation. It is named as such because it is the third generation of the standards of telecommunication hardware. It is also the general technology for mobile networking, passing the recent 2.5G. The technology is founded on the ITU or International Telecommunication Union group of standards which belongs to the IMT-2000.

4G is the fourth generation of mobile phone mobile communications standards. It is a successor of the third generation (3G) standards. A 4G system provides mobile ultra-broadband Internet access.

2. Background difference:
In 3g technology which is founded on the ITU or International Telecommunication Union group of a standard which belongs to the IMT-2000 use W-CDMA technology. It allows operators to provide users a bigger range of the latest services, as it gets bigger network capacity via heightened spectral efficiency. The included services are video calls, wide-area wireless voice telephone and broadband wireless information all included within the mobile environment. Whereas 4G technology which was started within cable television industry in 2009 which make users to explore new downloading speeds and capabilities. The utilization of LTE mobile broadband technology is an opportunity for the corporation to expand its horizons into 4G territory, upstaging current 3G capabilities. The necessity for 4G networks is associated with the increased utilization of data websites such as You Tube and Facebook, which require tremendous bandwidth in order to be used successfully. 2.1 3G stands for 3rd generation while 4G stands for 4th generation: 3G is currently the world’s best connection method when it comes to mobile phones, and especially mobile Internet. 3G stands for 3rd generation as it is just that in terms of the evolutionary path of the mobile phone industry. 4G means 4th generation. This is a set of standard that is being developed as a future successor of 3G in the very near future.

Architectural difference: both the Figures below provide the key components of these two architectures.

Several key differences in a LTE network enable more flexibility in its architecture than in a 3G . A functional representation of 3G network architecture is shown in Figure 1. In this network, the Base Terminal Station (BTS)/NodeBs aggregate the radio access network (RAN) traffic and transport it over a mobile
