Introduction

Wi-Fi is now a commonly used connection method for indoor wireless communications, starting first with smartphones and PCs. Moreover, with the spread of IoT, wireless LAN (WLAN) technology, supporting configuration of high-speed, large-capacity, low-cost communications environments is being used increasingly by home electrical goods, such as televisions, automobiles, and industrial machinery.

Automotive

Navigation systems, infotainment, automobile firmware updates

Home Use

Wi-Fi routers, smartphones, PCs, TVs, home electrical goods

IEEE802.11

Wi-Fi Alliance

Manufacture

Facility management, robotics remote control
