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 (now known as Inseego Corp.) owns a registered trademark on the "MiFi" brand name; in the United Kingdom mobile operator Hutchison 3G owns the "MiFi" trademark.

In September 2016 Novatel Wireless announced that it has agreed to sell the MiFi brand to TCL Industries Holdings of Hong Kong; the sale is expected to close in early 2017, pending approval from shareholders and regulators.
