Wireless internet, often referred to as Wi-Fi, allows devices to connect to the internet without physical cables. It uses radio waves to transmit data between a router and devices like smartphones, laptops, and tablets. This technology enables users to access the internet from various locations within the range of the wireless signal. To use wireless internet, a modem connects to an internet service provider, and the router broadcasts the signal. Users can connect multiple devices simultaneously, making it convenient for homes, offices, and public spaces. Wireless internet has become essential for everyday activities like browsing, streaming, and online communication.
