Depending on the frequency used for data transmission, the area covered, or the type of the device used for
data transfer, the following categories of wireless networks might be available to you.
Wireless LAN
A wireless LAN covers a relatively small geographic area, such as an office building or a house. Devices
based on the 802.11 standards can connect to this network.
Wireless WAN
A wireless WAN covers a broader geographic area. Cellular networks are used for data transmission, and
access is provided by a wireless service carrier.
Bluetooth
Bluetooth is one of a number of technologies used to create a wireless personal area network. Bluetooth
can connect devices a short distance from one another, and is commonly used for connecting peripheral
devices to a computer, transferring data between hand-held devices and a personal computer, or remotely
controlling and communicating with devices such as mobile phones.
