Real-time operation of LTE/Wi-Fi interworking via NS-3 and SDR interfacing

Recent approaches to augment LTE capacity through carrier aggregation of the unlicensed bands have drawn significant research interest. This carrier aggregation can either be realised via LTE/Wi-Fi interworking or from LTE directly operating over the unlicensed bands. However, these techniques face technological challenges that still need to be addressed in order to guarantee successful operation and fair coexistence with WiFi. This demo presents a unified experimental platform to evaluate and analyze the existing 3GPP LTE/Wi-Fi interworking approaches. This platform can be used to identify the merits and drawbacks of each approach in addition to characterizing their performance in the presence of realistic channel conditions.
