Abstract

Femtocells, a type of small cellular tower, are becoming more commonly used by wireless service providers for their benefits over the traditional macrocells such as better data rates and indoor coverage. However, due to the limited range of femtocells, service providers must accommodate for users of both types of towers, resulting in a need for optimized bandwidth allocation. In order to study this optimization, a computer software package called Octave is used to model the bandwidth for femtocells and macrocells. The model takes into consideration various parameters such as a user’s data rate and the provider’s revenue to determine the ideal allocation. After completing a base model, an initial run was verified with another scientific journal to ensure its accuracy by testing a predetermined set of parameters. From this preliminary model, certain parameters including the utility a user receives from a given amount of data and total bandwidth were altered to further investigate certain conditions. Through testing these parameters, patterns were identified of how each parameter effects a service provider’s allocation. These findings will be presented at IMSAloquium. Overall, these results will help define the optimal bandwidth allocation between femtocells and macrocells for cellular service providers.
