Wireless connections

Wireless connection is the transfer of data without the use of cables by means of radio waves only.

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 may be available to you:

Wireless LAN

A wireless local area network covers a relatively small geographic area, such as an office building or a

house. Devices based on the IEEE 802.11 standards can connect to this network.

Wireless WAN

A wireless wide area network covers a broader geographic area. Cellular networks are used for data

transmission, and access is provided by a wireless service carrier.

Bluetooth

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 PC, or remotely controlling and communicating

with devices such as mobile phones.

Wireless USB

This wireless analog of the USB standard can create a wireless personal area network by implementing

short-range large-bandwidth radio transmissions. It is used primarily for connecting a PC to peripherals that

are no more than a short distance from the host.
