GNU/Linux Rapid Embedded Programming

Chapter 13. Wireless Network Device - WLAN

The Ethernet connection discussed in the previous chapter allows several devices to talk each other. However, we need a wired connection to do that job. In this chapter, we will take a look at the wireless network devices that allow communication between several computers, but doing it without using wires. What is really interesting in using these networking interfaces is that a large part of communication protocols used on Ethernet interfaces can be used with these devices too!

We'll take a brief look at the basics of wireless devices in the Linux kernel and, of course, in our embedded kits. Then, we'll see an example of how we can do an encrypted connection with a normal access point using a wireless ...
