SubSection 4.3 - Network Types Comparison and Differences

First lets name the different types of Network Types and explain, then compare them.
  • Broadband
  • Dial-Up
  • Wireless
  • Bluetooth
  • Cellular

Broadband

  • Broadband is the communication from the internet to the computer, it refers to the telecommunication in which a wide band of frequencies can transmit information.
    • DSL

      • Short for Digital Subscriber Line, is a high-speed data and voice and transmission line that uses telephone wire to transmit data. A DSL can transmit data speeds up to 1.5 Mps in both directions. Unlike POTS this service you can transmit voice and data over the same wire at the same time, so basically you can talk on the phone and use the internet at the same time.
    • Cable

      • Many homes have cable wires already in there home, that they use to connect to cable modems
        and then the modem would connect to the computer and so on. Cable connections can transmit speeds from 500Kps up to 5Mbps. When using a cable connection you are using transceivers (transmitter/receiver) commonly known as cable modems. Cable modems the data is converted from digital to analog signals and place on the cable wire the same time as the incoming television signal. Then converted analog back to digital to be able to communicate with the computer.
    • Satellite

      • When using satellite you would have a satellite dish on yours house/company/etc and the dish will send and receive data from a satellite in the sky which directs the data from the internet provider or vice versa. The data speed rates for satellite can reach up to 1.5Mbps depending on your ISP (Internet Service Provider).
    • Fiber Optic

      • Using a Fiber Optic network is very different then most of the others. Fiber Optic uses light burst to transmit data from point A to point B and the wires for Fiber Optic are glass. Fiber Optics can transmit data up to speeds of 10Gbps going over distances of 2 meters to 40 kilometers.

Wireless

  • Wireless is the new upcoming thing in connecting to the internet, where ever there is wireless avalible you can connect t it, no wires needed!
    • 802.11

      • There are many differen types
        • 802.11b wireless - transfer speeds of 5.5Mbps or 11Mbps
        • 802.11g wireless - transfer speeds up to 54Mps
        • 802.11a wireless - transfer speeds up to 54Mbps

Cellular

  • Whenever you have a cellular ecption on your phone you can have connection to the internet. Cellular providers have two types of major services right now.
    • 3G - The most common used today, this can get transfer rates from as low as 2Mbps up to 14.1Mbps.
    • 4G- this type can go from speeds of 100Mbps up to 1Gbps.

Compare and Contrast

  • When choosing whihc service is best it is all up to the surroundings. Many places can have connections like DSL and Cable, but in a area with no telephone poles or cable you would need something like satellite connection. iber Optic would be the fastest out of all of these but its the most expensive and very difficult to install. When you can use your wireless and cellular almost anywhere . It is up Fto you !
