Types of wireless networks:

Wireless PAN:

• Wireless personal area networks (WPANs) interconnect devices within a relatively small area, that is generally within a person's reach.

•  For example, both Bluetooth radio and invisible infrared light provides a WPAN for interconnecting a headset to a laptop. 

• ZigBee also supports WPAN applications.^[6] Wi-Fi PANs are becoming commonplace (2010) as equipment designers start to integrate Wi-Fi into a variety of consumer electronic devices. 

• Intel "My WiFi" and Windows 7"virtual Wi-Fi" capabilities have made Wi-Fi PANs simpler and easier to set up and configure.
