Throughput and Latency Evaluation of a 4G LTE Network Driven by SDR and Open-Source LTE Software

Abstract:

The use of software defined radio (SDR) on the deployment of wireless communication standards is widely investigated for its low cost in the implementation by using the same hardware and fourth-generation (4G) long-term-evolution (LTE) networks are also part of this new communications paradigm. Furthermore, 4G networks enabled by SDR allows practical learning in a real environments that facilitate the development of technical skills without the inherent difficulty and cost associated with radio frequency components and regulation. In this paper, a 4G LTE network driven by SDR hardware and software-radio-system-LTE (srsLTE) that is an open-source LTE software platform is evaluated in terms of the throughput and latency. Besides, three different scenarios are implemented in order to evaluate the 4G LTE network by traffic injection through Iperf3 application and calculating internet throughput using the Fast web tool. The results show that the reached measurements are near to the theoretical parameters of 4G LTE networks. Thus, the implemented network is can be used as a testbed and is useful for teaching.
