Satellite - STP stands for Satellite Transport Protocol. It has a low bandwidth and low connectivity

HTTP - Hypertext transfer protocol is used to communicate with the webpage and request the selected webpage.

IrDA -  Infrared data association is a simplex communication as you aren’t receiving any information back from it. An example of an IrDA protocol would be the one used in remote control. This type of communication needs to have line of sight.

Cellular radio/network - Cellular radio is a simplex communication as radio waves don’t pick up any responses.  This broadcasts a message that most media devices can pick up.

GSM/UMTS - (Global System for Mobile communication) is a standard for describing 2nd generation digital cellular networks (2G).

IEEE WiFi802.11 standards - This is the standard that defines a wireless interface between the clients. This specific wireless standard is used for WLANs (wireless local area network) The IEEE stands for Institute of Electrical and Electronics Engineers.

TCP/IP - Transfer control protocol. This protocol is used for sending and receiving information over the internet. This protocol requires information to be sent back confirming that the first packet was sent and arrived correctly without any corruptions.

Ethernet - Ethernet is a network communication standard and is used to create LANs. They transmit at speeds between 10mb/s and 100mb/s.

Frame Relay - Frame Relay is a protocol standard for local area network. It is used for fast transmitting.
They travel through virtual circuits. This means they take the logical paths from the origination. The frame relay protocol replaces the header of a packet with a 2 bit header and that contains the destination address. Frame relay increase reliability of the communication lines.

ATM -  ATM protocol is used to support voice and data communications at high speeds.
ATM uses the data link layer in the OSI  model. Synchronous and Asynchronous.

Token Ring - Token ring is where the computers are connected in a ring called a LAN.
It is used to stop any collision in the network as all the traffic goes one way. This can be slow for the network.

UDP - UDP stands for User Data protocol. This, like TCP is a transportation protocol except that it doesn’t require a reply/confirmation for the next packet to be sent. This protocol uses less bandwidth than TCP. This protocol is used for online streaming etc. so you can get a smoother running picture instead of having to wait for it to buffer.


  1. handy stuff, following for more !:)

  2. LTE seems to be the rage these days, what exactly is it if you compare to other ways of transferring mobile data?
