Wireless Transmission Media

Wireless Transmission Media links two or more computers in a network where cables cannot be laid.

Microwaves
Microwaves are unidirectional and travel in a straight
line. They provide line-of-sight transmission, which
means there should not be any obstruction between
the transmitter and receiver. They are used for
transmitting radio and television signals and long- Transmitter Receiver
distance communications.

Radio Waves
Radio waves are omnidirectional and travel long distances in all directions
from the source. They can penetrate buildings easily and are widely used for
indoor and outdoor communication.

Satellite Communication
Satellite communication involves a network of satellites all around the
globe that can receive and transmit signals using microwaves from one
point to another. A single satellite can cover a large number of earth
stations.
Satellite communication is fast, reliable, and accurate. It is free from
interference and can carry a large number of signals at the same time.
Satellite communication is used for voice, data, fax, video, cellular phone,
and e-mail services.

Wi-Fi
Wi-Fi is a wireless technology that uses radio waves to transmit and
receive data. Wi-Fi technology is commonly used in PANs and LANs and
provides wireless connectivity to Internet networks.

Bluetooth
Bluetooth is a wireless technology used for exchanging data over short
distances (approximately 10 metre). Bluetooth technology is typically used
to transfer pictures, songs, and data files between smartphones, laptops,
and tablets.

Infrared

Infrared is wireless transmission media that sends signals using infrared light
waves. Infrared technology is used in remote controls for television and other
electronic devices.
