• Wi-Fi, short for Wireless Fidelity, is the term used to describe high speed wireless network connections over short distances between mobile computing devices such as laptops, smart phones, tablets and the internet. These are sometimes termed wireless local area networks or WLAN's. Wi-Fi is also increasingly used for communication between consumer electronic devices such as televisions, household appliances, DVD & Blue Ray players, digital cameras and mobile phones. Wi-Fi networks use very low powered radio technologies to transmit and receive information in a very similar way to home cordless phones.
