Wireless networks
Networks[1]
A wireless local-area network (LAN) uses radio waves to connect devices such as laptops to the Internet and to your business network and its applications. When you connect a laptop to a WiFi hotspot at a cafe, hotel, airport lounge, or other public place, you're connecting to that business's wireless network.[2].
Advantages of wireless networks[edit]
The text below is used with gratitude from Cisco Systems [3]
- Convenience. Access your network resources from any location within your wireless network's coverage area or from any WiFi hotspot.
- Mobility. You're no longer tied to your desk, as you were with a wired connection. You and your employees can go online in conference room meetings, for example.
- Productivity. Wireless access to the Internet and to your company's key applications and resources helps your staff get the job done and encourages collaboration.
- Easy setup. You don't have to string cables, so installation can be quick and cost-effective.
- Expandable. You can easily expand wireless networks with existing equipment, while a wired network might require additional wiring.
- Security. Advances in wireless networks provide robust security protections.
- Cost. Because wireless networks eliminate or reduce wiring costs, they can cost less to operate than wired networks.
