Second, MFemtocells can contribute to signaling overhead reduction of the network.
For instance, an MFemtocell can perform a handover on behalf of all its associated users, which can reduce the handover activities for users within the MFemtocell. This makes the deployment of MFemtocells suitable for high-mobility environments.
In addition, the energy consumption of users inside an MFemtocell can be reduced due to relatively shorter communication range and low signaling overhead.
