A map to understand Wi-Fi and Mi-Fi difference

It is also a shared network, and only one letter difference, but Mi-Fi and Wi-Fi are completely different things.

Intuitive point of view, the biggest difference is:One is physical, one is calling for a technology. So, you can say it with a Mi-Fi device can achieve Wi-Fi sharing.

From the source of the signal, Mi-Fi is to 2g / 3g / 4g signal to a network share, traffic from the "calling card"; but we often say Wi-Fi is to achieve a network shared by routers and other equipment, traffic from Broadband.
