Wi fi Technology
Wi-Fi allows devices to connect to the Internet without wires using radio signals transmitted through antennas. A Wi-Fi enabled device can connect to the Internet when within range of a wireless network connected to the Internet via an access point. While early city-wide Wi-Fi networks proved difficult to implement, Wi-Fi is now widely used with over 220,000 public hotspots and tens of millions of homes using the technology. The current WPA2 encryption is considered secure when strong passphrases are used. A wireless router receives radio signals from devices, decodes them, and sends information to the Internet via wired Ethernet connection.
