Electronic devices use Wi-Fi to supply a high-speed Internet connection by communicating over a wireless signal. The link works without any wired connection between the dispatcher and recipient. Wi-Fi is a high-frequency radio signal that can be picked up by electronic devices that have Wi-Fi capabilities.
These devices include computers, game consoles, home networks, mobile phones and tablets. Wi-Fi is a term that is trademarked by the Wi-Fi Alliance and means IEEE 802.11x. While home network and mobile plans are often costly, there are many ways to access free Wi-Fi. Hotels, fast food restaurants and coffee shops provide free Wi-Fi in hopes of maintaining happy costumers.
