i. A mobile base station (BS) in an urban environment has a power measurement of 45 W at 285 m. If the propagation follows an inverse 4th power law (Section 3.2.2), what is a reasonable power value, in W, to assume 1.14 km from the BS? Express your answer in scientific notation to 2 decimal places. ii. While you are travelling, the mobile phone app you have installed displays a received signal strength of 72 nW. Assuming the same propagation law as in part (i), how far are you from the BS? Give your answer in km to two decimal places. i.
