How Does Wireless Networking Work?

A Wi-Fi network allows devices to connect to the internet without using cables. It starts with an internet connection from an Internet Service Provider (ISP), which is connected to a router. The router acts as the central hub and creates a wireless signal using radio waves. When devices like smartphones, laptops, or tablets want to connect, they search for available Wi-Fi networks. After selecting a network and entering the password, the device sends a connection request to the router, which assigns it an IP address. Data is then transmitted back and forth between the device and the router using radio signals, allowing users to browse the internet and communicate wirelessly. Security measures like passwords keep the network safe from unauthorized access.
