Wireless networks use radio waves to connect devices such as laptops to the Internet, the business network and applications. When laptops are connected to Wi-Fi hot spots in public places, the connection is established to that business’s wireless network.

There are four main types of wireless networks:

• Wireless Local Area Network (LAN): Links two or more devices using a wireless distribution method, providing a connection through access points to the wider Internet.
• Wireless Metropolitan Area Networks (MAN): Connects several wireless LANs.
• Wireless Wide Area Network (WAN): Covers large areas such as neighboring towns and cities.
• Wireless Personal Area Network (PAN): Interconnects devices in a short span, generally within a person’s reach.
