What are transmission media?
TRANSMISSION MEDIA
This page explores transmission media: the physical and wireless channels through which data travels across a network. Transmission media can be broadly divided into two categories: wired and wireless.
Wired Transmission
Physical cables that carry data through electrical signals or light pulses, generally offering faster speeds and more stable connections.
Wired Transmission
Wired transmission means transmitting data through physical cables, such as Ethernet cables, copper wires, coaxial cables, or fibre optic cables.
UTP/Ethernet Cable
A UTP, or Ethernet, cable is a type of wired network cable that uses RJ45 connectors to transmit data between devices.
Copper Wire
Copper wire is wire made from copper. In networking, it carries data as electrical signals through a cable.
Coaxial Cable
A coaxial cable is a wire used to transmit high-frequency signals with minimal interference.
Fibre Optic
Fibre optic cable uses light to send data. It can transmit information very quickly over long distances.
Wireless Transmission
Technologies that transmit data through the air using radio waves, infrared, or satellite signals.
Wireless Transmission
Wireless transmission means transmitting data through the air using electromagnetic energy, such as radio waves or satellite signals.
Wi-Fi
Wi-Fi provides high-speed internet access to many devices without the need for a wired network connection.
Cellular Network
A cellular network connects devices to the internet through cell towers, allowing mobile devices to communicate over long distances.
Satellite
Satellites are spacecraft launched into space by launch systems. They can help transmit network signals across large distances, including remote areas.
Bluetooth
Bluetooth is used for connecting nearby devices to each other so they can exchange data wirelessly.
Zigbee, Z-Wave and Matter
Zigbee, Z-Wave, and Matter are wireless technologies used by smart home and Internet of Things devices to communicate with each other.
