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. A wireless network allows devices to stay connected to the network but roam untethered to any wires. The biggest advantage to wireless networking is that your device is not tethered to a router.

Previously it was thought that wired networks were faster and more secure than wireless networks. But continual enhancements to wireless network technology has eroded the speed and security differences between wired and wireless networks. Access points amplify Wi-Fi signals, so a device can be far from a router but still be connected to the network. You can easily expand wireless networks with existing equipment, whereas a wired network might require additional wiring. Because wireless networks eliminate or reduce wiring expenses, they can cost less to operate than wired networks. You don’t have to string any cables, so installation can be quick and cost effective.
