MiFi is sometimes referred to as a personal "hotspot", which can simplify the process of setting up a small LAN. MiFi can support no less than 5 users at the same time (depending on the device), including digital cameras, laptops, games and multimedia. All Wi Fi enabled devices can access the Internet. MiFi devices can be used to set up specific networks and share network connections anywhere through cellular connections. Many smart phones have similar functions, but MiFi charges are more favorable.
