Wi-Fi uses radio signals to transmit data wirelessly between devices like old radios and TVs. Hotspots provide public Wi-Fi access in locations such as hotels, restaurants, malls, universities, and airports. The advantages of Wi-Fi are that it has no wires, fast deployment, and fast data transfer rates. However, Wi-Fi also has limitations such as a limited range, security risks, high power consumption, and interference from other devices.
