Network Transmission Media

• Transmission media


  The channel in which data can be sent through
• Wireless media


  • Uses radio waves to communicate
  • Includes standards like Wi-Fi and Bluetooth
• Wi-Fi


  Wireless communication standard that uses a specific frequency range
• Bluetooth


  Wireless communication standard with a smaller range than Wi-Fi, used for personal devices
• Bluetooth vs Wi-Fi


  Bluetooth has lower bandwidth than Wi-Fi, but is more flexible and easier to set up
• Wired media


  Transmits data using electrical signals through physical cables
• Copper cables


  • Made of parallel copper wires
  • Suffer from crosstalk interference between wires
• Coaxial cables


  • Wrap insulation around copper to reduce interference
• Fiber optic cables


  • Use pulses of light to transmit data
  • Have very low latency and high bandwidth
  • But are more expensive and can be brittle
