The constant evolution and growth of the multimedia applications supported by today s mobile devices leads to an increase on the demand of video based services which impose some new requirements in terms of bitrate and delay. In order to face these challenges, LTE appears as a technology capable of dealing with the video trafic load on mobile networks. However, given the inherent nature of the mobile networks, and in order to take advantage of the bitrates that can be achieved with this technology, the devices located at the cell s edge face some dificulties when a certain SINR must be achieved. To overcome this issue, LTE Advanced comes into the picture as it makes use of Relay Nodes (RN) which were included as part of the network architecture. Based on simulations, the present work evaluates the performance of real time applications on devices located at the cell s edge. The results show the advantage of using Relay Nodes in LTE in aspects such as the reduction of lost packets and the increase of throughput, leading to an improvement of the video quality at the receiver s side.
