Abstract
The incredible increase in wireless data traffic makes it crucial to search for approaches to further improve spectrally efficient systems such as LTE networks in low bands using advanced spectral efficiency techniques. Limitations on hardware implementation and channel conditions, as well as the increase in system complexity due to the use of advanced techniques, may lead to limits on the viability of such approaches. To solve the problem of growing usage of wireless data, capacity enhancement approaches are considered, such as moving up in frequency into the unused spectrum in which huge bandwidths are available. Comparing with approaches that rely on the use of highly complex techniques, moving up frequency may be a promising approach to guaranteeing the fairness of traffic and achieving high data rates. A capacity enhancement approach to enhancing fairness of traffic in LTE networks by utilising the unused bandwidths of idle or less dense basestations toward crowded areas by dynamic mobility of basestations is proposed in this paper. The approach is empirically tested to show the easy evolution to higher system capacities and improve the spectral efficiency where data demands further increase. A simulation method is utilised in this paper, and the simulation is carried out using an NS2 simulator, and the results presented in the simulation section are based upon a number of runs.
