    Lightbulb What you need to set up a home network in Windows

    With the variety of options for home networking available in the market, make buying decisions difficult. Before you decide what hardware to get, you should decide what type of network technology (the way computers in a network connect to or communicate with one another) to use. This article describes and compares the most common network technologies and lists hardware requirements for each.

    Network technologies

    The most common types of network technology are wireless, Ethernet, HomePNA, and Powerline. When choosing a network technology, consider the location of your computers and the desired speed of your network. The costs of these technologies are similar. The sections below compare these four technologies.

    Wireless
    Wireless networks use radio waves to send information between computers. The three most common wireless network standards are 802.11b, 802.11g, and 802.11a. A new standard, 802.11n, is expected to grow in popularity.

    Speed

    802.11b: transfers data at a maximum rate of 11 megabits per second (Mbps). Downloading a 10 megabyte (MB) photo from the Internet under optimal conditions takes about 7 seconds.

    802.11g: transfers data at a maximum rate of 54 Mbps. Downloading a 10 megabyte (MB) photo from the Internet under optimal conditions takes about 1.5 seconds.

    802.11a: transfers data at a maximum rate of 54 Mbps. Downloading a 10 megabyte (MB) photo from the Internet under optimal conditions takes about 1.5 seconds.

    802.11n: depending upon the number of data streams the hardware supports, 802.11n can theoretically transmit data at up to 150 Mbps, 300 Mbps, 450 Mbps, or 600 Mbps.

    Note
    The transfer times listed are under ideal conditions. They arenít necessarily achievable under normal circumstances because of differences in hardware, web servers, network traffic conditions, and so on.

    Merits

    • Itís easy to move computers around because there are no cables.
    • Wireless networks are usually easier to install than Ethernet.


    Demerits

    • Wireless is often slower than the other three technologies.


    Wireless can be affected by interference from things such as walls, large metal objects, and pipes. Also, many cordless phones and microwave ovens can interfere with wireless networks when theyíre in use.

    Wireless networks are typically about half as fast as their rated speed under all but ideal conditions.


    Ethernet
    Ethernet networks use Ethernet cables to send information between computers. Ethernet transfers data at up to 10, 100, or 1000 Mbps, depending on the type of cables used. Gigabit Ethernet is the fastest, with a transfer rate of up to 1 gigabit per second (or 1000 Mbps).

    For example, downloading a 10 megabyte (MB) photo from the Internet under optimal conditions can take about 8 seconds on a 10 Mbps network, about 1 second on a 100 Mbps network, and less than a second on a 1000 Mbps network.

    Merits

    • Ethernet networks are inexpensive and fast.


    Demerits

    • Ethernet cables must be run between each computer and a hub, switch, or router, which can be time-consuming and difficult when the computers are in different rooms.

    HomePNA
    HomePNA networks use existing home telephone wires to send information between computers. HomePNA 2.0 transfers data at up to 10 Mbps. HomePNA 3.0 transfers data at up to 128 Mbps.

    For example, downloading a 10 megabyte (MB) photo from the Internet under optimal conditions can take about 8 seconds on a HomePNA 2.0 network and about 1 second on a HomePNA 3.0 network.

    Merits

    • HomePNA uses the existing telephone wiring in your home.
    • You donít need hubs or switches to connect more than two computers in a HomePNA network.

    Demerits



    • You need a phone jack in each room where you want to have a computer, and all jacks must be on the same phone line.

    Powerline
    Powerline networks use existing home electrical wiring to send information between computers. A Powerline network can transfer data at up to 200 Mbps.

    For example, downloading a 10 megabyte (MB) photo from the Internet under optimal conditions can take less than a second on a Powerline network.

    Merits

    • Powerline uses the existing electrical wiring in your home.
    • You donít need hubs or switches to connect more than two computers in a Powerline network.

    Demerits

    • You need an electrical outlet in each room where you want to have a computer.
    • Powerline networks can be affected by interference and "noise" on the line.

    Hardware requirements
    There are several kinds of hardware used in home networks:

    Network adapters:
    These adapters (also called network interface cards, or NICs) connect computers to a network so that they can communicate. A network adapter can be connected to the USB or Ethernet port on your computer or installed inside your computer in an available Peripheral Component Interconnect (PCI) expansion slot.

    Network hubs and switches: Hubs and switches connect two or more computers to an Ethernet network. A switch costs a little more than a hub, but itís faster.



    Routers and access points: Routers connect computers and networks to each other (for example, a router can connect your home network to the Internet). Routers also enable you to share a single Internet connection among several computers. Routers can be wired or wireless. You donít need to use a router for a wired network but we recommend it if you want to share an Internet connection. If you want to share an Internet connection over a wireless network, you will need a wireless router. Access points allow computers and devices to connect to a wireless network.



    Modems:
    Computers use modems to send and receive information over telephone or cable lines. You will need a modem if you want to connect to the Internet. Some cable providers supply a cable modemóeither free or for purchaseówhen you order cable Internet service. Modem-and-router combination devices are also available.

    Cable modem: Network cables (Ethernet, HomePNA, and Powerline): Network cables connect computers to each other and to other related hardware, such as hubs, routers, and external network adapters. HomePNA and Powerline adapters are often external and connect to a computer with either Ethernet cables or USB cables, depending on the type of adapter.

    Itís a good idea to find out what kind of network adapters your computers have, if any. You might decide to go with a certain technology because you already have most of the hardware, or you might decide to upgrade your hardware. A combination of technologies might work best for your environment. For example, many people use a wireless router, which accommodates both wired Ethernet connections for desktop computers and wireless connections for laptops.
