Figure 4: Spatial power density emitted from the secondary deployment area obtained by solving the optimization problem (12a)–(12c) when taking into account (a) only TV protection constraints (12b) with protection distance 0  km, (b) both TV and secondary constraints (12b), (12c) with protection distance 1 1  km, and (c) only TV protection constraints (12b) with protection distance 1 1  km.
