Wi-Fi, short for Wireless Fidelity, is a technology that allows devices such as smartphones, tablets, laptops, and other devices to connect to the Internet wirelessly without the need for physical cables. Wi-Fi uses radio waves to transmit data between devices and a Wi-Fi router or access point, which is connected to an Internet service provider (ISP) that provides Internet connectivity.

To connect to Wi-Fi, you need a device with Wi-Fi capabilities, such as a smartphone, tablet, or laptop, and a Wi-Fi network to connect to. The Wi-Fi network can be set up in a home, office, or public place such as a coffee shop, library, or airport. Most modern devices come with built-in Wi-Fi capabilities, and you can usually connect to a Wi-Fi network by selecting the network name (also known as SSID) from the list of available networks on your device, and entering the password, if required.

Once connected to a Wi-Fi network, your device can access the Internet, allowing you to browse websites, use online services, stream videos, and perform other online activities. Wi-Fi has become a ubiquitous technology that has enabled the proliferation of wireless Internet access in homes, businesses, and public spaces, providing convenience and flexibility in accessing the Internet without the need for physical cables.

It’s important to note that Wi-Fi is a local area network (LAN) technology, which means its range is limited to a specific area around the Wi-Fi router or access point. The range can vary depending on the router’s capabilities, environmental factors such as walls and interference, and the type of Wi-Fi technology being used (e.g., 802.11n, 802.11ac, 802.11ax). Typically, Wi-Fi signals can cover a range of several dozen to a few hundred feet.
