Preface

There are many books on data communication networks, and so one would ask why write another one. Almost all the books written so far are written for graduate students. The few that are written for an undergraduate audience are aimed at business students who need to understand the buzzwords that they will be encountering in the marketing and sale of data communication equipment. There is no book written for undergraduate electrical engineering students who study the different components of the data communication technologies in isolation. Thus, this book grew out of the following observations:

  1. 1. While electrical and computer engineering students study how to build filters in circuit theory class and Fourier analysis, sampling theorem, and modulation in signal and systems, no concerted effort is made to combine these topics into one system that they can relate to.
  2. 2. In this information age, most undergraduate electrical and computer engineering students do not know what an IP address is, how to design a data network, or how domain name system (DNS) works.
  3. 3. While every student uses a mobile device, most undergraduate engineering students in general and undergraduate electrical and computer engineering students in particular do not know what 2G, 3G, and 4G networks are. To them these are mere buzzwords.
  4. 4. Data security is a very important issue and still many undergraduate electrical and computer engineering students do not understand the basic concepts of data security. ...
