FERMI: A FEmtocell Resource Management System for Interference Mitigation in OFDMA Networks

The demand for increased spectral efficiencies is driving the next generation broadband access networks towards deploying smaller cells (femtocells) and sophisticated air interface technologies (Orthogonal Frequency Division Multiple Access or OFDMA). The dense deployment of femtocells however, makes interference and hence resource management both critical and extremely challenging. In this paper, the authors design and implement one of the first resource management systems, FERMI, for OFDMA-based femtocell networks. They implement FERMI on a prototype four-cell WiMAX femtocell testbed and show that it yields significant gains over conventional approaches.
