Understanding the Different Pieces of Hardware

So you want to set up a new wireless network in your home or office. Or, you want to extend an existing wire line network to provide wireless capabilities. In either case, relax! These are pretty easy things to do using Wi-Fi technology. You'll have your wireless network up and running in no time—and be using your computer in your living room, in your garden or on your deck, and from all kinds of unlikely places.

This chapter will not discuss in detail the differences between the various Wi-Fi protocols (principally 802.11b and 802.11g) because they are amply discussed in Chapter 2, “Understanding Wi-Fi,” and Appendix A, “Wireless Standards.” But you should bear the different flavors of Wi-Fi in mind when you decide which equipment to buy, both from the viewpoint of economics, and how fast your network will run. In a nutshell, 802.11b is cheaper, but 802.11g is faster.
