Resumo

Video traffic increase in mobile networks, impose new requirements in terms of bitrate and delay. LTE technology appears capable of facing this demand challenges. However, given the inherent nature of the mobile networks, the devices located at the cell’s edge face difficulties to achieve the required SINR. To overcome this issue, LTE Advanced includes Relay Nodes (RN) as part of the network architecture. The present work evaluates, through simulations, the performance of real time video using LTE and Relay Nodes. The results highligh the enhanced quality of video obtained at the receiver’s side.
