WiFi is the nickname for Wireless Fidelity - high speed internet and network connection without the use of wires, cables and other stuff you can trip over.
Wi-Fi (as in âWireless Fidelityâ) A standard for connecting electronic devices without the use of wires, Wi-Fi enables you to use your laptop or smartphone within a convenient range of use.
