Summary

Like rock ’n’ roll, wireless technologies are here to stay, and for those of us who have come to depend on wireless technologies, it's actually pretty hard to imagine a world without wireless networks—what did we do before cell phones?

So, I began this chapter by exploring the essentials and fundamentals of how wireless networks function.

Springing off that foundation, I then introduced you to the basics of wireless RF and the IEEE standards. I discussed 802.11 from its inception through its evolution to current and near future standards and talked about the subcommittees that create them.

All of this led into a discussion of wireless security—or, rather, nonsecurity for the most part.
