WIRELESS NETWORKING TECHNOLOGY
In a wireless networking technology, no wires 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. There
are two types of wireless technologies named Wi-Fi and Bluetooth.
Wi-Fi
Wi–Fi is the most popular wireless communication technology
used for homes, private business LANs and public hotspots. A
Wi-Fi enabled device such as a PC, video game console, mobile
phones 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.
Wi-fi
Bluetooth
Bluetooth is a technology that enables wireless
communication between low-power consumption devices
within a short range (1 meter, 10 meters, 100 meters). It
facilitates communication between different devices when
they are within a required range. The latest version of
Bluetooth, Bluetooth 5.4 technology provides data transfer
speed up to 2 Mbps.
Bluetooth
It provides a way to connect and exchange information between devices such as mobile phones,
telephones, laptops, printers, personal computers, GPS receivers (Global Positioning System)
through 2.4 GHz short range radio frequency bandwidth.
PROTOCOL
Protocol is a set of rules that governs the communication between computers on a network.
Certain network protocols and standards must be followed in order to ensure that your computer
can communicate with another computer over a network.
