Chapter 3 Mobile Radio Propagation: Large-Scale Path Loss 1. (a) Explain the advantages and disadvantages of the 2-ray ground reflection model in the analysis of path loss. (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
