LTE Emulation over Wired Ethernet

Long-Term Evolution (LTE) standard merges an all IP voice and data communications with dynamic spectrum resource scheduling. The resource scheduler must balance the QoS requirements, traffic demands, and physical channel conditions to create desirable wireless enduser performance. The purpose of our research and the focus of this paper is a development of a unified testbed platform based on Emulab that can be used to examine the key aspects of an LTE system in realtime, including real time uplink and downlink scheduling, QoS parameters, and Android end-user applications. Our validation studies demonstrate that the testbed is capable of achieving delay, loss, and jitter that can be associated with an LTE communication system, and can be easily used to study a variety of LTE scheduling algorithms.
