Indoor Positioning in Wireless Local Area Networks with Online Path-Loss Parameter Estimation

Figure 6

Computer experiments concerning slow fading in the setup of Figure 2 when a −5 dB step variation of the parameter of a single AP at 𝑘=500 is imposed in order to mimic a sudden shadowing; here 𝜎²_ℎ=9, 𝜎²_𝑦=5, and 𝑁_𝑝=500.
