A wireless local-area network (LAN) uses radio waves to connect
devices such as laptops and mobile phones to the Internet and to your
business network and its applications. When you connect to a Wi-Fi
hotspot at a cafe, a hotel, an airport lounge, or another public place, you’re
connecting to that business’s wireless network.A wired network uses
cables to connect devices, such as laptop or desktop computers, to the
Internet or another network.
A wireless network allows devices to stay connected to the network but

device can be far from a router but still be connected to the network. A
wired network has some disadvantages when compared to a wireless
network. The biggest disadvantage is that your device is tethered to a
