MiFi stands for Mobile WiFi. A MiFi works in the same way as a WiFi router, with the difference that you can set up a wireless personal area network and get online where ever you are on the globe. 4G-LTE routers belong to the fourth generation routers that use the "long-Term Evolution Technology" (LTE). This LTE technology is the successor of 3G technologies such as UMTS, HSDPA and HSUPA. The latest generation 4 g LTE MiFi routers are very compact and stylish.
