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

Wireless communication is the transfer of information between two or more points that are not connected by an electrical conductor. The most common wireless technologies use radio. With radio waves distances can be short‚ such as a few meters for television or as far as thousands or even millions of kilometers for deep-space radio communications. It encompasses various types of fixed‚ mobile‚ and portable applications‚ including two-way radios‚ cellular telephones‚ personal digital assistants
