WiFi can save money for those who use a lot of internet of their mobile devices, be it smartphones or even tablets that are connected to a service provider for wireless usage.
Using a router in our home and office allows the internet connection from our ISP (internet service provider) and use it wirelessly through WiFi. Doing this allows multiple devices and/or computers to access the internet connection at one time. WiFi also allows the devices connected to it, to connect to each other when the devices themselves have the capability.
