MiFi

MiFi is a brand name used to describe a wireless router that acts as mobile Wi-Fi hotspot. In many countries, including the United States, Canada and Mexico, Novatel Wireless owns a registered trademark on the "MiFi" brand name, except in the UK where mobile operator 3 owns the "MiFi" trademark. Novatel Wireless has never offered an "official" explanation for the origins of the name "MiFi"; it may be short for either "Mobile Wi-Fi", "My Wi-Fi" or simply they were stumped for a name and turned the W on its head.
