Software-Based Implementation of Dual Connectivity for LTE

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.
