Tiivistelmä
Use of multimedia services, such as streaming of high quality videos on mobile devices is increasing drastically which requires high data rate and bandwidth on mobile devices. Therefore LTE system is introduced by 3GPP which promises higher throughput on mobile devices i.e. 326.4 Mbps in downlink and 86.4 Mbps in uplink.
Theoritically LTE system promises high throughput, high bandwidth utilization, low latency, high spectral efficiency, and high peak data rates than all other 3GPP technologies. The main motive behind this research is to analyze the LTE system performance in practical scenarios to estimate the practical system throughput and peak data rates in different situations.
LTE system level simulation are performed in this thesis to evaluate the performance in practical scenarios. The simulation are performed with LTE system level simulator to calculate the user and cell thoughput of the LTE network in different practical scenarios such as outdoor, indoor, deep indoor and in car with different network layouts, antenna downtilt angles and MIMO.
Simulation results show that the LTE system user and cell thoughput are greatly affected by interference from the neighbouring cells and are different in practical situation than in theory. Results also show that the interference can be reduced by using different network layouts, antenna downtilting and MIMO. Hence high system throughput can be achieved by mitigating the effect of interference from the neighboring cells.
