History of Wi-Fi: From Wireless Experiments to the Invisible Internet

Before smartphones quietly connected to a network in your pocket, before coffee shops advertised free Wi-Fi, and before a router became an almost invisible piece of household furniture, there was a long history of experiments, engineering problems, competing technologies, scientific discoveries, and standards battles.

History of Wi-Fi traces the remarkable story behind one of modern life's most familiar technologies. Beginning with the early development of wireless communication and radio experimentation, this book follows the technological path that eventually led to wireless local area networking and the standards that made Wi-Fi practical on a global scale.

Along the way, it explores the development of radio technologies, packet networking, spread-spectrum techniques, wireless LAN research, IEEE 802.11, the growth of consumer wireless networking, and the arrival of Wi-Fi in laptops, smartphones, homes, businesses, airports, cafés, and public spaces.

The story also introduces the researchers, engineers, organizations, standards bodies, and companies whose documented work helped transform wireless networking from a specialized technical concept into everyday infrastructure.

But Wi-Fi is not simply the story of faster internet access. It is also a history of solving difficult problems: how to send information through the air, how to share limited radio spectrum, how to reduce interference, how to make incompatible devices communicate, and how to turn complicated engineering into something ordinary people could use without thinking about it.

From early wireless experiments to the invisible networks surrounding us today, this is the story of how the world learned to communicate without plugging everything in.

Because the strangest part of Wi-Fi history is that its greatest success is almost impossible to see.
