Wi-Fi signals: Wi-Fi uses radio waves to transmit data between devices. These radio waves operate on different frequencies and are sent out by a wireless transmitter.
Wireless router: A wireless router is a device that connects to your internet service provider's network and broadcasts Wi-Fi signals. It acts as a central hub that allows multiple devices to connect wirelessly.
Device connection: Devices like smartphones or laptops have Wi-Fi receivers built-in. These receivers detect the Wi-Fi signals from the router and establish a connection.
Network authentication: To connect to a Wi-Fi network, you usually need a password. This security measure ensures that only authorized users can access the network.
Data transmission: Once connected, devices can send and receive data through the Wi-Fi network. This includes browsing the internet, streaming videos, transferring files, or using online services.
Range and speed: Wi-Fi signals have a limited range, typically a few hundred feet indoors. The distance can vary depending on the router's power and obstacles like walls or furniture. The speed of Wi-Fi depends on factors such as the router's capabilities, signal quality, and the number of connected devices.
Interference: Other devices and physical objects can interfere with Wi-Fi signals. Common sources of interference include microwave ovens, cordless phones, and neighboring Wi-Fi networks operating on the same or nearby channels.

Wi-Fi has become an essential part of our daily lives, providing wireless connectivity and enabling us to stay connected, access information, and interact with various online services.
