Wi-Fi stands for Wireless Fidelity. It is a technology that allows devices to connect to a network wirelessly using radio waves.
How Wi-Fi works
- Transmission of Radio Signals - Wi-Fi uses radio waves to transmit data between a router (or access point) and connected devices. The router emits radio signals over specific frequencies (typically 2.4 GHz and 5 GHz), which devices like smartphones, laptops, and tablets use to communicate with the network.
- SSID and Authentication - Each Wi-Fi network is identified by a unique name called the SSID (Service Set Identifier). When a device wants to connect to a Wi-Fi network, it searches for available SSIDs, selects the appropriate network, and may need to authenticate using a password or other security measures.
- Data Packet Exchange - Once connected, data is sent in the form of packets between the router and the device. The router manages traffic and ensures that data packets are correctly routed to their destination, allowing for internet access and communication between devices on the same network.
