MiFi stands for "my Wi-Fi" and is pronounced as "my-Fi."

MiFi is a portable broadband wireless device that combines functions of a router, modem and access point usually about the size of a credit card.

Also known as a personal hotspot. MiFi was designed to simplify setting up of small local area networks (LAN), or an ad-hoc network. MiFi devices support up to five users and can also network Wi-Fi-capable devices including cell phones, digital cameras, notebooks, MP3 players and gaming systems. A MiFi device gets Internet connection almost anywhere with cellular connectivity.
I just got a MiFi hook up and it works great.

Possibly the best nickname in the world. Only a very special person will ever be called MiFi. She would have to be the best person in the world. She would be the smartest, most amazing friend ever. You can only call your true bestie MiFi. She would have to mean the world to you. So much that you would feel comfortable to call her this. She is so amazing, and you never want her to leave. She is a true friend. Nothing not ever moving across the world could change that.
