Chapter 1 Overview of Wireless Communication Systems Problems? 1. As w arehousing gift increases, we can store larger and larger amounts of selective information 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 close to distance. Discuss the pros and cons of putting a large number of these storage devices in a truck and driving them to their destination alternatively than direct the data electronically. 2. Describe two technical advantages and disadvantages of radio 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 vocalize system is 30 milliseconds, which of these satellite systems would be acceptable for two-p art phonate communication? 4. Figure 1.1 indicates a relatively savourless growth for wireless data between 1995 and 2000. What applications might importantly increase the growth rate of wireless data users. 5.

This chore illustrates some of the economic issues facing benefit suppliers as they transmigrate away from vocalise-only systems to mixed-media systems. Suppose you are a service provider with 120KHz of bandwidth which you must allot between interpreter and data users. The voice users require 20Khz of bandwidth, and the data users require 60KHz of bandwidth. So, for example, you could allocate a ll of your bandwidth to voice users, resulti! ng in 6 voice channels, or you could divide the bandwidth to discombobulate 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 extraction of a timeslot and both types of calls last T seconds. There are six independent voice users in the system: to each one of these users requests a voice channel...If you want to light a total essay, order it on our website: OrderCustomPaper.com
