Long Term Evolution (LTE) is the fourth generation standard for mobile communication system developed by Third Generation Partnership Project (3GPP) to face the growing demand of Internet. Mobility enhancement is adopted in LTE network to support higher mobility speeds. Hence, the performance of LTE network under various mobility speeds is highly concerned. In this paper, simulation experiments are conducted to examine the LTE network performance in an urban environment under various mobility speeds of 3, 30 and 120 km/h. The simulations are modelled in a multiple cells scenario where intra-handover is taken into consideration. Extensive simulations show that the aggregate throughput of the video flows is higher in 3 km/h scenario (60.9% and 163.5%) as compared to 30 km/h and 120 km/h scenarios respectively. Meanwhile, the performance of the delay and packet loss ratio are also lower in the slower mobility speeds scenario. However, the fairness metric is higher (up to 47.1%) during the high mobility speeds.
