It has been known for centuries that information is power. What was not known for centuries was how to store information and knowledge in such a way that it can be accessed by everybody from anywhere, anytime. (Alrefai, AbuAli, & Mohammad, 2011) We rely on our cell phones, mobile computers and tablets more and more each day. We are always on the go and we like having the world at our fingertips. The next generation wireless network, as dictated by the standards, creates the opportunity to offer high-speed data services, to build simplified network architecture, and to reduce different operations. Today we can have information access from anywhere all the time even in a state of mobility. Buzzwords such as mobile, ubiquitous, nomadic, untethered, pervasive, and any time anywhere, are used by different people to refer to the new breed of computing that utilizes small portable devices and wireless communication networks. (Alrefai, AbuAli, & Mohammad, 2011) Just as each generation of a family leaves behind footprints of a rich history for the next generation to follow, generations of mobile telephone systems follow the same unique path. The First generation or 1G Mobile telephony system focused on delivering advanced mobile phone service in North America with allocated bandwidth of two 25mHz; one for transmission from base to mobile unit and the second one for transmission from mobile unit to base. The second generation or 2G uses digital encoding, 2G networks support high bit rate voice, limited data communication and different levels of encryption. In 2G systems the data transfer rate is only around 9.6 kpbs, which is far too slow for retrieving rich information comprising text and images. (Alrefai, AbuAli, & Mohammad, 2011) Each new generation usually brings new base technologies, more network capacity for more data
