Best Demo Award a la IEEE International Conference on Mobile Ad-Hoc and Smart Systems (MASS) 2019 One of the major challenges of current mobile networks is to increase the per-user data rate without significant infrastructure cost and using the already existing physical resources, i.e., the bandwidth. In this sense, Dual Connectivity emerges as a promising solution for LTE and future 5G to increase the throughput with minor changes in current systems. This work presents the implementation of the U-Plane of Dual Connectivity for LTE using the open source software Open Air Interface with commodity hardware and the impact of this technology on UDP and TCP performance. This work has been supported by the European Project DualConnectivity Solution for ORCA (DALI) as part of the OpenCall 2 of H2020-ICT-2016-2017 (ORCA) project.
