(b) What insight does the 2-ray model provide about large-scale path loss that was disregarded when cellular systems used very large cells? 2 .In a 2-ray ground reflected model‚ assume that must be kept below 6.261 radians for phase cancellation reasons. Assuming a receiver height of 2 m‚ and given a requirement that be less than 50 ‚ what are the minimum allowable values for the T-R separation distance and the height of the transmitter antenna
