| dc.description.abstract | Recently, the mobile wireless communication technology has become one of the most important fields which still in a significant growth that because to keep abreast of the progress that occur in broadband services field such as video on demand, images, internet protocol TV, video conferencing, and high definition TV. The mobile wireless network in every ten years appears a new generation since the first appearance by 1G system, the first introduced in the year 1980 which was based on the technology of analogue transfer for only voice calls., then the 2G system which begun appearance in the year of 1992, while this technique adopted to digital transmission technique which allowed the transfer of data on communications networks, in addition to voice calls that adoption one of a standard GSM or CDMA for calls and speed of these networks was about 9.6Kbps, and later to the intermediate networks called 2.5G, which appeared with the standard GPRS which allowed for transfer the better data with speeds of about 400Kbps. Then emerged the largest 3G networks at speeds up to 2Mbps, the third generation (3G) that started to roll out in 2001 and this technique provides a package of services and audio separately. The next development of generation systems is the 4G (fourth generation) which started appearance in the year 2010.
The main objective of this paper is to display a comparison of all generations of mobile technologies before the 4G LTE Network, the architecture of 4G LTE Network, QoS and bearer service architecture of the 4G LTE Network. | en_US |
