Types of Communications Protocols and standards

Syllabus Detail

  • Types of communication protocols and standards 12 ATAR

Wireless - Bluetooth

  • Is a technology standard for exchanging data over short distances (usually sub 10m) by using short wavelengths with frequencies ranging from 2.4-2.45GHz.

Wireless - Ethernet

  • Wireless in a school uses ethernet and wireless access points (WAPs) to receive the signal. This is in a common local area network (LAN) setup.

Wireless - 802.11x

  • 802.11 is a standard for wireless communications.
  • It provides standards for how wireless networking devices should work and be setup.
  • the x refers to the version. eg 802.11a started in 1999, 802.11g started in 2003 and was much better.
  • 802.11n was the next improved version.
  • 802.11ac is most common today and is enhanced as it has wider channels for carrying signals. eg 80 or 160 MHz versus 40 MHz) in the 5 GHz band for 802.11n

Wireless - Radio Frequency Identification (RFID)

  • An RFID is a small chip that usually carries 2000 bytes of data or less which acts as a barcode or a magnetic strip (like on a credit card). It acts as a unique identifier and must be scanned to retrieve the information.
  • It can be attached to clothes in shops, which can buzz as they past the scanner if someone tries to steal the clothes.
  • Sporting stars wear them so their coaches can track how far they run in a game.

Wireless - Wireless Application Protocol

  • Is a technical standard showing how wireless hardware should be setup on a mobile wireless network.

Wired - 802.3 ethernet

  • Is a standard for wired ethernet.
  • It gives the rules for how wired network hardware must work.
  • Standard connections in a school LAN that use wire, must use the 802.3 standard.

TCP/IP

  • Transmission Control Protocol/ Internet Protocol gives the unique IP addresses needed for internet devices to work.
  • It gives the rules for how wired network hardware must work.
  • Standard connections in a school LAN that use wire, must use the 802.3 standard.
  • The IP4 version of TCP/IP uses 32 bit addressing. Can provide 4 billion addresses like 192.168.0.9
  • The IP6 version of TCP/IP uses 128 bit addressing. Can provide trillions more than IP4.
