This tutorial is designed for beginners only and This tutorial explains the basics of shell programming by showing some examples of shell programs. Its not help or manual for the shell. While reading this tutorial you can find manual quite useful (type man bash at $ prompt to see manual pages). Manual contains all necessary information you need, but it won’t have that much examples, which makes idea more clear. For that reason, this tutorial contains examples rather than all the features of shell. I assumes you have at least working knowledge of Linux i.e. basic commands like how to create, copy, remove files/directories etc or how to use editor like vi or mcedit and login to your system.

Wireless technology is the method of delivering data from one point to another without using physical wires, and includes radio, cellular, infrared, and satellite.A historic perspective will provide you with a general understanding of the substantial evolution that has taken place in this area.The common wireless networks of today originated from many evolutionary stages of wireless communications and telegraph and radio applications. Although some discoveries occurred in the early 1800s, much of the evolution of wireless communication began with the emergence of the electrical age and was affected by modern economics as much as by discoveries in physics.

This eBook will cover the followings:

• Step-by-Step Instructions for Designing a Wireless Project from
  Inception to Completion
• Everything You Need to Know about Bluetooth,LMDS, 802.11, and
  Other Popular Standards
• Complete Coverage of Fixed Wireless,Mobile Wireless, and Optical
