4) Using the Free Space Path Loss model equation, see equation section, calculate the path loss for signals of 2.5GHz and 5.8Ghz at a distance of 1.2km between the transmitter and receiver. Assuming that the minimum power level that your receiver can detect is -100dBm, can you use detect and use these signals? Justify your answer. [Note :there are marks for the calculation BUT it is your justification that is more important.] 5) An EM wave is propagating at a velocity of 2.16 x 107 m.s1 and has a frequency of 1.35MHz. Calculate the phase constant, ß, associated with this wave. 6) For an EM wave propagating in one medium meets the boundary of a second medium. Calculate the amount of the EM wave that is reflected and transmitted at the boundary layer if the refractive index level of the 2nd material is 4 times that of the initial material. 7) Given that the velocity of propagation in a material is 1.75 x108 m.s-1 and the propagation constant, ß, has a value of 47 rads.m-1 calculate the frequency of the EM wave.
