On Accurate Simulations of LTE Femtocells Using an Open Source Simulator
Long-Term Evolution (LTE) femtocells represent a very promising answer to the ever growing bandwidth demand of mobile applications. They can be easily deployed without requiring a centralized planning, to provide high data rate connectivity with a limited coverage. In this way, the overall capacity of the cellular network can be greatly improved. At the same time, the uncoordinated setup of femtocells poses new issues that require a deep and thorough analysis before spreading this technology worldwide. Unfortunately, to the best of the authors' knowledge, no accurate simulation tools are freely available for enabling this kind of investigation. Thus, they present in this paper a simulation tool for LTE femtocells, implemented as a module of the emerging open source LTE-sim framework.
