What is WiFi and how does it work?
WiFi, short for Wireless Fidelity, is a technology that allows devices like computers, smartphones, and tablets to connect to the internet wirelessly, using radio waves. It operates through a router that communicates with your internet service provider (ISP), which provides the connection to the broader internet. Essentially, the router converts data from the internet into a wireless signal that your devices can receive and interpret.
When your device connects to the WiFi network, it can send and receive data packets through the air thanks to antennas in both the router and the device. The 2.4 GHz and 5 GHz frequency bands are commonly used for WiFi, allowing multiple devices to connect and communicate simultaneously. This technology is widely used for convenience and increased mobility, enabling users to access the internet from virtually anywhere within the network’s range.
