Where to Begin
This book was created by a team of individuals who each, in their own field,
are actively participating in the ever-expanding Internet by pushing its reach
farther than ever before. The massive popularity of wireless networking has
caused equipment costs to continually plummet, while equipment capabilities
continue to sharply increase. We believe that by taking advantage of this
state of affairs, people can finally begin to have a stake in building their own
communications infrastructure. We hope to not only convince you that this is
possible, but also show how we have done it, and to give you the information
and tools you need to start a network project in your local community.
Wireless infrastructure can be built for very little cost compared to traditional
wired alternatives. But building wireless networks is only partly about saving
money. By providing people in your local community with cheaper and easier
access to information, they will directly benefit from what the Internet has to
offer. The time and effort saved by having access to the global network of
information translates into wealth on a local scale, as more work can be done
in less time and with less effort.
Likewise, the network becomes all the more valuable as more people are
connected to it. Communities connected to the Internet at high speed have a
voice in a global marketplace, where transactions happen around the world
at the speed of light. People all over the world are finding that Internet access
gives them a voice to discuss their problems, politics, and whatever
else is important to their lives, in a way that the telephone and television simply
cannot compete with. What has until recently sounded like science fiction
is now becoming a reality, and that reality is being built on wireless networks

But even without access to the Internet, wireless community networks have
tremendous value. They allow people to collaborate on projects across wide
distances. Voice communications, email, and other data can be exchanged
for very little cost. By getting local people involved in the construction of the
network, knowledge and trust are spread throughout the community, and
people begin to understand the importance of having a share in their communications
infrastructure. Ultimately, they realize that communication networks
are built to allow people to connect with each other.
In this book we will focus on wireless data networking technologies in the
802.11 family. While such a network can carry data, voice, and video (as
well as traditional web and Internet traffic), the networks described in this
book are data networks. We specifically do not cover GSM, CDMA, or other
wireless voice technologies, since the cost of deploying these technologies is
well beyond the reach of most community projects.
