3G is the generic abbreviation for 3rd generation. It is the wireless technology that initially enabled Internet browsing over wireless networks. An example of 3G technologies is EV-DO. 4G is the generic abbreviation for 4th generation. It is the wireless technology that was designed to optimize data over wireless networks, improving the speed and efficiency of data delivery. LTE is one of the technologies that can be used to build a 4G network. This research will compare contrast 3G wireless networks to 4G networks.

Compare and contrast 3G wireless networks to 4G networks in terms of:

3G Wide Brand Wireless Network is used with which the clarity increases and gives the perfection as like that of a real conversation. The data are sent through the technology called Packet Switching. Voice calls are interpreted through Circuit Switching. It is a highly sophisticated form of communication that has come up in the last decade. In addition to verbal communication it includes data services, access to television/video, categorizing it into triple play service. 3G operates at a range of 2100MHz and has a bandwidth of 15-20MHz. High speed internet service, video chatting are the assets of 3G.

With the help of 3G, we can access many new services such as GLOBAL ROAMING. Another thing to be noted in case of 3G is that Wide Band Voice Channel that is by this the world has been contracted to a little village because a person can contact with other person located in any part of the world and can even send messages too. Then the point to be noted is that 3G gives clarity of voice as well can talk with out any disturbance. Not only these but also have entertainments such as Fast Communication, Internet, Mobile T.V, Video Conferencing, Video Calls, Multi Media Messaging Service (MMS), 3D gaming, Multi-Gaming etc are also available with 3G phones.

The Internet speed of 4G mobile services is 100MBPS (21 MB per second), when compared to the low speed of 21MBPS in 3G mobiles. 4G promise a downloading speed of 100Mbps and are yet to shower its wonders on. Then with the case of Fourth Generation that is 4G in addition to that of the services of 3G some additional features such as Multi-Media Newspapers, also to watch T.V programs with the clarity as to that of an ordinary T.V. In addition, we can send Data much faster that that of the previous generations.

The convenience of a faster Internet browsing is the main benefit of 4G when compared to 3G mobiles. In 4G mobiles, videos and other things can be downloaded at a speed that is four times


Nowadays, many wireless carriers use different technologies that they call “4G”. There is Verizon has LTE, Sprint has WiMax, T-Mobile and AT&T have HSPA+, although AT&T plans to switch to LTE at some point this summeLTE, WiMax and HSPA+ are very different networks. In a recent past, HSPA+ was still considered as a 3.5G network. Somewhere along the way, carriers using it felt the pressure from competitors using the term “4G”, and decided to promote HSPA+ to “4G” status. That was an easy upgrade…

WiMax was the first network to be called “4G” in the USA. When it was introduced it was clearly faster, with downloads speeds of 5Mbps.

Forthcoming 4G networks will enable users to freely roam across different communication systems. This implies that formerly independent wireless and wired technologies will be integrated to deliver transparent access to a plethora of mobile services and applications. This will also involve changes in the user’s experience mainly derived from (1) mobility across heterogeneous technologies, (2) drastic changes in the underlying link conditions, and (3) continuous adaptation of applications, e.g. flexible coding schemes. This chapter presents a detailed study of these so far unknown phenomena arising in the context of 4G networks. Current instrumental models employed to estimate user...
