What is the function of WiFi technology?

WiFi technology is designed primarily to provide wireless internet access. It operates by using radio waves to transmit data between a router and devices such as computers, smartphones, and tablets within a specific range. This wireless connectivity enables users to access the internet without the need for physical cables, facilitating the seamless transmission of data across a network.

The ability to connect to the internet wirelessly has become essential for convenience in modern living, supporting various applications, from casual browsing to streaming services and online gaming. Additionally, WiFi technology can connect multiple devices simultaneously, making it a scalable solution for homes, offices, and public spaces. The emphasis on wireless connectivity distinguishes WiFi from other technologies, such as infrared, which relies on line-of-sight and is generally limited to short distances. Similarly, cellular signal enhancement and Bluetooth pairing serve different purposes and do not fall under the primary function of WiFi.
