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 8

Overall capacity contour plots in Mbps of the five indicative underground MV/BPL topologies versus repeaters distance from point A—see Figure 2—when three-hop repeater system is deployed for different coupling schemes (distance span is equal to 10 m). Blue stars indicate maximum overall capacities.
