How does Wi-Fi work in mobile?

Wi-Fi (short for "Wireless Fidelity") is a wireless networking technology that allows devices such as computers, smartphones, and tablets to connect to the Internet and other network resources without the need for a physical Ethernet connection. Here's how Wi-Fi works in mobile devices:

The device has a Wi-Fi module or adapter: Most modern mobile devices come with built-in Wi-Fi, but if you are using an older device, you may need to purchase a separate Wi-Fi adapter.

The device scans for available Wi-Fi networks: When you enable Wi-Fi on your mobile device, it will automatically scan for available Wi-Fi networks in range. You can usually see a list of available networks by going to the Wi-Fi settings menu on your device.

The device connects to a Wi-Fi network: Once you have selected the desired Wi-Fi network, you may need to enter a password if the network is password-protected. Once you have entered the password, your device should connect to the Wi-Fi network.

The device accesses the Internet and other network resources: Once your mobile device is connected to a Wi-Fi network, it should be able to access the Internet and other network resources, such as shared files and printers.

It's important to note that not all Wi-Fi networks are open and available for anyone to use. Some networks may be protected by a password or may require you to authenticate before you can connect. In these cases, you will need to obtain the necessary login credentials or authentication information in order to access the network.

Overall, Wi-Fi allows mobile devices to connect to the Internet and other network resources wirelessly, providing a convenient and widely-used technology for accessing the Internet from almost anywhere.
