Chapter 1 Overview of Wireless Communication Systems Problems? 1. As memory board natural endowment increases, we can store larger and larger amounts of entropy on smaller and smaller storage devices. Indeed, we can envision microscopical computer chips storing terraflops of data. Suppose this data is to be transfered over just about distance. Discuss the pros and cons of putting a large number of these storage devices in a truck and driving them to their destination sort of than direct the data electronically. 2. Describe two technical advantages and disadvantages of radio set systems that persona bursty data transmission rather than continuous data transmission. 3. Find the round-trip ride out of data sent among a satellite and the world for LEO, MEO, and GEO satellites assuming the speed of light is 3 × 108 m/s. If the utmost acceptable delay for a sum system is 30 milliseconds, which of these satellite systems would be acceptable for bipartizan parting communication? 4. Figure 1.1 indicates a relatively at once growth for wireless data between 1995 and 2000. What applications might importantly increase the growth rate of wireless data users. 5.

This enigma illustrates some of the economic issues facing benefit suppliers as they immigrate away from theatrical role-only systems to mixed-media systems. Suppose you are a service provider with 120KHz of bandwidth which you must allot between voice and data users. The voice users require 20Khz of bandwidth, and the data users require 60KHz of bandwidth. So, for example, you could allocate all of your bandwidth to voice users, resulting in! 6 voice channels, or you could divide the bandwidth to bemuse one data channel and collar voice channels, etc. Suppose further that this is a time-division system, with timeslots of date T. All voice and data call requests come in at the first gear of a timeslot and both types of calls last T seconds. There are six independent voice users in the system: for each one of these users requests a voice channel...If you want to light a undecomposed essay, order it on our website: OrderCustomPaper.com
