WIRELESS NETWORKING TECHNOLOGY
In a wireless networking technology, no wire or physical media is used for connecting computers. It
uses electromagnetic waves like infrared, microwave and radio waves for transmission of the data. The
choice of the technology depends on the distance and speed of transmission. Two common types of
wireless technologies are Wi-Fi and Bluetooth.
Wi-Fi
Wi–Fi is the most popular wireless communication technology
used in homes, private business LANs and public hotspots. A
Wi-Fi enabled device such as a PC, video game console, mobile
phone or MP3 player can connect to the Internet when it comes
within the range of a wireless network. Wi-Fi allows us to deploy
local area networks without wires thus reduces the cost of the
network expansion.
