(b) A mobile network designer estimated that the size of the first Fresnel zone in the middle of a 2 km link be 7.84 m. The towers (transmitter and receiver) are 10 m tall. (i) What is the maximum usable frequency to be used for this communication? (ii) How tall could an obstructed structure at that midpoint be to clear 60% of the first zone (i.e. 40% of blocking)?
