Review and Progress towards the Capacity Boost of Overhead and Underground Medium-Voltage and Low-Voltage Broadband over Power Lines Networks: Cooperative Communications through Two- and Three-Hop Repeater Systems

Figure 11

Maximum overall capacity of distribution BPL topologies with three-hop repeater systems (in green), distribution BPL topologies with two-hop repeater systems (in red), and conventional distribution BPL topologies (in blue) when different indicative BPL topologies and coupling scheme occur (OV: overhead, UN: underground, WtG1: WtG1 coupling scheme, WtW1_2: coupling scheme, StP1: StP1 coupling scheme, and PtP1_2: coupling scheme).
