Introducing the Mifi (Mobile Wifi). Well there are people who have never heard of it. It's a portable router that works the same as tethering 3G/LTE with your smartphone to share the connection with other devices through Wifi.
Some people may ask. Why do we even need this if we can tether with our smartphones? Well, tethering uses a lot of battery, and heats up the phone quickly. You still need your phone for call and messaging don't you? Besides, some old devices (e.g Nintendo DS) have some issues supporting ad-hoc connections like smartphone tethering. In those cases Mifi would be your saviour.
In addition, Mifi can be used like a 3G/LTE dongle. You know those USB dongles that you connect to your PC/Laptop for 3G/LTE connection? Well, Mifi does that too. And just like your usual router, there is also an admin web interface where you can type in the router's IP address on your browser and log in to edit port forwarding, port triggering, WEP/WPA passwords and many other router settings.
When you sign up for Mobile Broadband in any of the telecom, they usually let you choose between two or more 3G/LTE devices, either a dongle or a Mifi device. You may require to pay slightly more for a Mifi device, but trust me, it's definitely more worth it compare to a dongle that can only be used on a PC/Laptop.
