If you set up a wireless network in your home or office, you'll probably spend most of your time on that network. However, when you wander away, your wireless adapter will let you access other networks, so why not take advantage of this? For example, you may be traveling and need to get online at the airport or hotel. In this case, you could connect to a commercial or community wireless network (or a cellular network, as described in Chapter 8).
In this chapter, I discuss some of the commercial and community wireless access providers and how you can use them while on the road. I also show you how to hunt for wireless networks using your existing hardware and some free software. This can come in handy when your travel involves a conference, since many conference organizers have begun to include free Wi-Fi as an added feature for attendees.
