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.
