A new access mode for femtocells in 5G networks

A femtocell is a small, and low-power cellular base station, typically designed for use in a home or a small business. Since femtocells are likely to be deployed by subscribers individually, we can expect the most of femtocells will be operating as the closed access mode that allows the only authorized users or owners to access the femtocell. Although a lot of femtocells are able to provide the network access covering a large area, they are only used by their owners in the deployed place. This paper addresses the inefficient femtocell operation and proposes a new access mode for femtocells which is called Give-And-Take (GAT) mode. This mode encourages users to share their femtocell access points, and resolve the femtocell inefficiency resulting from the closed access mode. This paper shows that GTA mode can be a feasible solution to improve the femtocell efficiency through a game theory model.
