Chapter 1 Overview of Wireless Communication Systems Problems? 1. As w atomic number 18housing endowment fund increases, we can store larger and larger amounts of info 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 near distance. Discuss the pros and cons of putting a large number of these storage devices in a truck and driving them to their destination quite than direct the data electronically. 2. Describe two technical advantages and disadvantages of radiocommunication 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 phrase system is 30 milliseconds, which of these satellite systems would be acceptable for bipartizan sound communication? 4. Figure 1.1 indicates a relatively straight off growth for wireless data between 1995 and 2000. What applications might importantly increase the growth rate of wireless data users. 5.

This problem illustrates some of the economic issues facing benefit providers as they emigrate away from fathom-only systems to mixed-media systems. Suppose you are a service provider with 120KHz of bandwidth which you must allot between character 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, resul! ting in 6 voice channels, or you could divide the bandwidth to baffle one data channel and collar voice channels, etcetera Suppose further that this is a time-division system, with timeslots of date T. All voice and data call requests come in at the commence of a timeslot and both types of calls last T seconds. There are six independent voice users in the system: each(prenominal) of these users requests a voice channel...If you want to light a safe essay, order it on our website: OrderCustomPaper.com
