This paper considers broadband potential of distribution Broadband over Power Lines (BPL) networks when different well-known\nnoise models of the BPL literature are applied. The contribution of this paper is twofold. First, the seven most representative and\nused noise models of the BPL literature are synopsized in this paper. With reference to this set, the broadband performance of a\ngreat number of distribution BPL topologies either Overhead (OV) or Underground (UN), either Medium-Voltage (MV) or Low-\nVoltage (LV), is investigated in terms of suitable capacity metrics. Second, based on the proposed capacity metrics, a comparative\ncapacity analysis is performed among various well-validated noise models.Through the careful study of its results, it is demonstrated\nthat during capacity computations of distribution BPL networks, the flat Additive White Gaussian Noise (FL noise model) can be\ncomfortably assumed as an efficient noise model either in 3ââ?¬â??30MHz or in 3ââ?¬â??88MHz frequency range since its capacity differences\nwith the other well-proven noise models are negligible.
