From café culture to home schooling, remote community networks, and smart cities, Wi-Fi is an invisible but fundamental element of contemporary life. Loosely regulated, low-cost, and largely overlooked by researchers, this technology has driven the rise of the smartphone and broadband internet, and is a vital element in the next wave of automation. Thomas, Wilken, and Rennie provide the first comprehensive account of the social and cultural consequences of Wi-Fi, highlighting the ways in which it has changed our homes, communities, and cities. They discuss its origins as an experimental technology, the conflicts generated around its ownership and control, and the ideas and expectations attached to it by technologists, activists, and entrepreneurs. The authors reveal the ways in which Wi-Fi is an inherently social and political technology, animated by conflicting aspirations for local, public, and community control, and defined by private and corporate interests. As this book shows, Wi-Fi has extended and intensified our online lives while also promising a more inclusive internet. Wi-Fi is essential reading for students and scholars of media and communication, as well as anyone who wants a better understanding of this ubiquitous and influential technology.

Wi-Fi has become the preferred means for connecting to the internet - at home, in the office, in hotels and at airports. Increasingly, Wi-Fi also provides internet access for remote communities where it is deployed by volunteers in community-based networks, by operators in 'hotspots' and by municipalities in 'hotzones'. This book traces the global success of Wi-Fi to the landmark change in radio spectrum policy by the US FCC in 1985, the initiative by NCR Corporation to start development of Wireless-LANs and the drive for an open standard IEEE 802.11, released in 1997. It also singles out and explains the significance of the initiative by Steve Jobs at Apple to include Wireless-LAN in the iBook, which moved the product from the early adopters to the mass market. The book explains these developments through first-hand accounts by industry practitioners and concludes with reflections and implications for government policy and firm strategy.

Sales of wireless LANs to home users and small businesses will soar this year, with products using IEEE 802.11 (Wi-Fi) technology leading the way, according to a report by Cahners research. Worldwide, consumers will buy 7.3 million wireless LAN nodes--which include client and network hub devices--up from about 4 million last year. This third book in the "HACKING" series from Syngress is written by the SoCalFreeNet Wireless Users Group and will cover 802.11a/b/g (“Wi-Fi ) projects teaching these millions of Wi-Fi users how to "mod" and "hack" Wi-Fi access points, network cards, and antennas to run various Linux distributions and create robust Wi-Fi networks. Cahners predicts that wireless LANs next year will gain on Ethernet as the most popular home network technology. Consumers will hook up 10.9 million Ethernet nodes and 7.3 million wireless out of a total of 14.4 million home LAN nodes shipped. This book will show Wi-Fi enthusiasts and consumers of Wi-Fi LANs who want to modify their Wi-Fi hardware how to build and deploy “homebrew Wi-Fi networks, both large and small. Wireless LANs next year will gain on Ethernet as the most popular home network technology. Consumers will hook up 10.9 million Ethernet nodes and 7.3 million wireless clients out of a total of 14.4 million home LAN nodes shipped. This book will use a series of detailed, inter-related projects to teach readers how to modify their Wi-Fi hardware to increase power and performance to match that of far more expensive enterprise networking products. Also features hacks to allow mobile laptop users to actively seek wireless connections everywhere they go! The authors are all members of the San Diego Wireless Users Group, which is famous for building some of the most innovative and powerful "home brew" Wi-Fi networks in the world.
