Wireless Local Area Network (WLAN)
Devices are connected wirelessly and cover a relatively small area, generally
within a house or a building. The wireless connection used for setting up
WLAN is generally Wi-Fi (802.11x).
Wireless Wide Area Network (WWAN)
Also known as Mobile Broadband, this service is generally provided by the
phone companies for use on mobile devices. A mobile device or laptop
must support WWAN technology to connect to this network.
Wireless Personal Area Network (WPAN)
Devices are generally connected wirelessly using Bluetooth, RF, Near-Field
Communication (NFC), and so on. This type of network generally operates
within a few feet of the devices.
