The ever-increasing growth of user demand, the limitations of the third generation of wireless mobile communication systems and the emergence of new mobile broadband technologies on the market have brought researchers and industries to a thorough reflection on the fourth generation The short fall of 3G networks is clear, it’s just not fast enough, offering 384kbps doesn’t meet the requirements of what the end user has come to expect these days.

Popping of generations:

First generation: This first generation (1G) analog system for mobile communications had seen key improvements during the 1970s. This was due to the invention of microprocessor and even the digitization of the control link between the mobile phone and the cell site.

Second generation (2G): By the end of the year 1980 the digital cellular systems were developed. These systems digitized the control link and the voice signal. These systems provided better voice quality with higher capacity which even   costed low.

Third generation (3G): These systems provide faster communication services which include: voice, fax, and internet. Momentous capacity, broadband capabilities to support greater numbers of voice and data customers.

But Why did 3G fail?

1 .High input fees for the 3G service licenses.

2.Current high debt of many telecommunication companies.

3.Challenge to build the necessary infrastructure for 3G.

4. Expense and bulk of 3G phones.

5. Lack of coverage because it is still new service

6.High prices of 3G mobile services in some countries.
