What exactly is WiFi? Why does accessing the internet on my phone without WiFi cost me data while being on WiFi doesn’t?
In: Technology
WiFi is connecting to the computer network for the building where you are, without using a cable. Whoever owns the building has to pay for internet access for their computers, and are letting you connect to the internet through their systems for free, as a courtesy.
Wireless Internet is connecting to the internet via the cellular (cell phone) antennas that are all over the city. You have to pay your own subscription / have a data plan for this.
