Abstract

The fourth-generation wireless network communications technology standard is called 4G. Users of 4G devices will have the ability to access applications ranging from basic voice communication to seamless real-time video streaming. This paper proposes new techniques for the 4G mobile system, which include base station and cell distribution, channel allocation, and carrier frequencies. In addition, the connection between cells with a new topology using the fiber optic system instead of the microwave link in the air interface is proposed. The results show that there is very good improvement in terms of signal strength, data rate, and quality of service by using the proposed radio access network, the fiber length depends on the cluster size, also, co-channel and adjacent channel interferences has been further reduced. The fourth generation system requires accessing and air interface at higher data rates, which can be achieved by these new proposed techniques as shown in the results.

Key words: 2G, 3G universal mobile telecommunications system (UMTS), long term evolution (LTE), 4G, cell planning, frequency, channel allocation
